Star Lock Washer

This tiny thing called star lock washer holds an important function in the security and safety of the driver and riders. It controls and stabilizes the movement of the spindle axle nut in order not to loosen and the roller bearing will not move wildly.

I am sharing my experience related to this one simple but important thing. When it was my first time to see and noticed this was about five years ago. I thought it’s a simple and useless thing.

It was when I felt that there is something abnormal in the movement of wheels. I know nothing about symptoms of bad bearings but I thought it would be something good to inspect your car when you suspect there is an abnormality.

So what I did is jacked up the front right wheels and tried to move it if it’s firm and secured. This way I’ve seen that the bearings were loose because I suspect that they are already bad so I took off the wheel, the star lock washer, the nut, the flat washer, and the bearings.

Roller bearing

You may need bearings, go here

I’m certain that the bearings have to be replaced so I went to the auto supply center to buy a new one. I’m back and I have to assemble everything. I replaced the roller bearings, tightened the nut, placed another washer next to the nut rather than the star lock washer.


Defective Star Lock Washer

The reason why I did not use the star lock washer is that it’s already defective. So I just tightened the nut and inserted the cotter pin.

Cotter pin

 

So this how it looks without the cotter pin.

 

The Result without the Star Lock Washer

Every after driving I have to inspect it. I always observe that the nut is loosened and I have to retighten so I thought of putting a washer with a thickness just enough between the nut and the cotter pin.

In doing so, we used the vehicle going to an affair of about 15 kilometers away from where I stay. And you know what happened? As the wheels turned the roller bearings moved and so with the spindle nut that got so tight and caused friction and it got so hot and melted the spindle thread and the bearings had wildly and freely moved and the wheel is no longer in the proper position. We left the car and rode on a tricycle to the occasion we are attending to.

After the occasion, we rode back but before reaching home the group went ahead and I slowly drove my car to my garage. The damage is severe and I’m worried where will I buy that spindle axle since it is an old model and it’s difficult to find a replacement.

The good thing is that as technology advances and inventions advances also there are technological remedies too for those who cannot cope up with the advancements. There is what we call a lathing machine which can be equally reliable.

So what you can see in the image below is a rebuild of the spindle axle.  The thread was restored but the same nut is used.

 

Now, I know I have to bring back the missing one, and that is the star lock washer. I have to look for the replacement of that very important part though tiny it is and is seemingly unimportant, the experience is the proof that it does an indispensable role in the safety of the whole vehicle and all that is there inside.

 

 

 

Since I have replaced that star lock washer I haven’t had a problem or an issue with the bearings and the nut. Everything works fine and I’m secured and have peace in mind.

Please watch the short video on how the star lock washer looks so simplistic but holds an irreversible role in the journey of everyone who boards the car.

 

Thank you for reading and following my story.  I hope it helped and inspired you as well as you have learned something is valuable when it comes to your relationship with your own car.

Rear Axle Seal Replacement

Rear Axle Seal Replacement

The facts

  1. The brake drum is wet with oil

  2. Brake lining is also wet with oil

  3. Brake fluid has no indication of leaking anywhere

  4. There are two oil seals in the rear axle, the inner oil seal and the outer rubber seal.

 

The video will show you the axle hub and outside and the inside or back of the brake disk.

I. Replacing the inner Oil Seal

No leak on the Motor Vehicle Wheel Cylinder

The First Time

I noticed that the brake drum has been wet with oil. I have to see what’s really making this little thing. I detached the wheel and detached the brake drum. I was wondering why the inner part of the brake drum and the brake lining were totally wet with something like grease. But I don’t see leaks from the motor vehicle wheel cylinder and no dissipation from the brake master assembly. So what I did is wash everything and assembled it back and continued to use to vehicle.

 

The Second Time

They say, history repeats itself and it is true. I saw again that the brake drum was wet.  This time I have in mind what is possible since I disregarded the possibility that it’s from the brake system.

 

 
I removed the wheel, detached the brake drum, detached the brake lining and also the axle. I removed the oil seal and replaced it with a new one.

Now, to test this and prove that what I did is the right thing, I will be fetching the young people from the Summer Camp in San Pablo City.  That is around 60 kilometers away from my place. So I will be running at 120 kilometers to and from.

To see this I will be giving an update tomorrow afternoon when I come back with eleven young people from the camp.

 

II. Replacing the Outer Rubber Seal

I promised to give you an update on what it took when I test the vehicle and see if what I did is the solution to the problem.

When I got home I did not bother to examine the thing until the following week. It seems the issue is lurking and I have to check it.

For the third time, I want to be sure if the issue has been resolved or is still lurking. Again, I removed one by one the parts and I saw that the brake linings and brake drum were wet with oil again.

In the rear axle hub, there are two oil seals and these are the images:

1. This first seal is placed here:

That oil seal is placed in the axle casing so it will fit in between that axle casing and the axle main bearing.

When the seal is replaced and the axle shaft is put back to its place it will look like the image below. You can see the nuts and bolts tightened together to hold the axle casing and the axle hub.

 

Rear Axle Seal Replacement-brake disc fastened to the axle casing

 

2. And this outer rubber seal is placed here:

Now, as you can see above the first oil seal, in other words, the inner axle oil seal is replaced already and when you assemble it, that’s how it looks.

For this time let’s replace the outer rubber seal which is the second seal in the axle assembly. But don’t be confused this must be done first before the whole axle assembly is placed back to the axle casing. We have just illustrated how and where the inner seal is to be.

The outer rubber seal is placed in between the axle hub and the brake disc. This will seal oil that may come out or slipt out of the axle main bearing.

If this outer rubber seal is installed it’s now time to assemble back the axle together with the brake disc where the axle main bearing is attached.

After it has been assembled it will look like the image below. It’s just a small part of the outer rubber seal is being exposed fitly in between the axle hub and the brake disc.

Axle Hub and Brake Disk with new outer rubber seal

Concluding words

What we’re trying to solve are the facts below:

  1. The brake drum is wet with oil
  2. Brake lining is also wet with oil
  3. Brake fluid has no indication of leaking anywhere

We have tried our best to solve for the first time by replacing the inner axle oil seal but we did not succeed. Nevertheless, I am happy that it was replaced because I know its time has come and we have to shoot two birds in one stone.

We have come to our sense that oil leakage is on the brake disc, the brake lining, brake drum but it does not come from the motor vehicle wheel cylinder. However, the oil leakage is on the outer side of the brake disc not in the inner side.

If it’s in the inner side and the problem is the inner oil seal it should show some signs in the image below. Don’t worry what you can see now is not a leakage but a spill when I adjusted the brake.

 

We have discovered the fact that the outer rubber seal has been the culprit why the problem has been lurking after we have done all other things.

After we have replaced that outer rubber seal, now, we have the peace of mind and safer and better driving with the dry brake drum, dry brake lining.

Brake Light Switch Replacement

BRAKE LIGHT SWITCH REPLACEMENT

Brake Light Switch Repair and Replacement-old brake light switch Brake Light Switch Repair and Replacement-old brake light switch

 

Does your brake lights switch needing a repair or does it need replacement? Let’s try to learn how this part works for our vehicle.

Brake lights are an important part of a vehicle. These are the lights placed at the right and the left side of the back of any vehicle. The use of this auto part is to warn the driver who is following after you on the road that you are slowing down or stopping by.

Brake Light Switch Repair and Replacement-brake light

 

Every driver can see anything in front of his car or vehicle but there are times especially when in dim light colors are optically deceiving. If there is a light that flashes or blinks the eyes will send a message to the brain that the car before you are slowing or stopping and you are already near to bump and the brain commands the foot to step on the brake.

 

What could be the issue and what could be done when your brake lights do not light on?

Switch on your Ignition switch but not necessarily starting the engine.

When you step on the brake pedal and one or both of the brake lights will not light on the possibilities are: busted bulbs or line disconnection.

But there is another way to check this, you place the clutch on the reverse and when the brake lights on then there are no disconnected lines and no bulbs busted.

Then the problem here would be brake light switch that is to be reconditioned or replaced.

 

Brake Light Switch Repair and Replacement-new brake light switch Brake Light Switch Repair and Replacement-new brake light switch

 

This auto part can be easily opened so you can see what is inside if it is only corrosion that you can clean or you need to replace it.  If you have cleaned any dirt inside and no rust that will continue to ruin the brake light switch then you may opt to just repair it. But if you think the problem will repeat itself in a short time you have to replace it.

As you can see it in the picture I bought a new brake light switch. I cleaned the old one and tested but it doesn’t work anymore.

RED COLOR BRAKE LIGHTS

For those who bought a second-hand vehicle, there may be modifications made as it is the fashion these days especially motorcycles. I’m sure it’s very rare in cars.

The standard color for brake lights is red, it is not white it is neither yellow. If it happens that it is not red then maybe they have erred in connecting the lines.

Brake Light Switch Repair and Replacement-standard color brake light

 

Let’s bear in mind that brake lights are important for the safety of everyone and not is just a decoration of a vehicle for the eyes to see and relish. So it is important that this part must be checked every time you travel because you are not only helping yourself but you are helping other drivers to take precautions in driving.  It will help eradicate accidents along the road. 

Thank you for reading this blog and if ever you agree or disagree with my opinion, please drop your comments and we will learn together saving lives through little things.

What is a Power Steering Pump

What is a Power Steering Pump?

Replace Power Steering Pump-Toyota L power steering pump

The power steering pump is an auto part that is used to help the driver whether a woman or a man steer the wheels in less effort regardless of car or truck sizes. This part is important especially when the car is moving forward and backward slowly more particularly on curve roads and maneuvers.

The pump is located in front of the engine and is attached to the steering gearbox.  Driven by the engine crankshaft through a belt-pulley mechanism, the steering pump compresses the hydraulic fluid which helps rotates the steering gearbox when steered by the driver.

When a car or a truck is equipped with power steering pump it would be easier for anyone even a woman to drive because the steering wheel is manageable and controllable by less effort.

However, if the power steering pump is defective even the strongest man will find difficulty and steering the wheels because you exert much effort.

Symptoms of a bad, failing, defective Power Steering Pump

  • A Squealing or Whining Sound

You will hear this at the moment you start your engine. It’s a sound that is abnormal, a sound that this time only you noticed about it. It’s not a part of the normal sounds that you always hear when you drive.

If you hear that kind of sound that means you are now having a failing, bad, or defective power steering pump. However, it does not mean that everything is bad, failing or defective and cannot be fixed. If you have heard that for the first time maybe your power steering pump is just lacking automatic transmission fluid (ATF). You better refill it. If you have refilled it and the sound remains maybe the next problem that you will encounter is stiff steering wheels.

Brake Pad Clips

Never underestimate the importance of the brake pad clips or brake pad springs. These are tiny things but they play significantly in the disc brake system.

Brake Pad Clips-pad clips

One day when I was driving to my church work going to the Worshiping Congregation which is about 10 kilometers away from the Mother Church. The spindle axle got loose threads and the spindle bearings were crushed.  As a result, the tire was no longer on its normal position so the rotor or the disc forced the brake pad to break from the normal position.  Because the clip can no longer hold the brake pads it was removed from its proper place and it was gone.

Brake Pad Clips-Restored spindle axle

Brake Pad Clips-Restored spindle axle threads

To cut the story short everything was fixed except for the clip which was not replaced because it’s out of stock in the market.

The truth of the fact is that anyone is discouraged to drive a vehicle without this little thing, the brake pad clip. Everything is no longer normal when not fixed or replaced as in the original part.

Functions

Brake pad clips or brake pad springs are the ones that clamp the brake pads to the caliper. Clips or springs hold the pads so they will not move if pressed on the spinning rotor.

 

Brake Pad Clips-clip

 

If it happens that the brake pad clips loosen and disentangled, the brake pad will move as it is pressed to the rotating rotor. If the brake pads have already worn and have enough space inside the caliper it might be forced to break and may cause the breakage of the caliper.

Brake Pad Clips-clip

There are a lot of clips different in forms depending on the car model you have or spindle assembly. The older models may be difficult to find such springs and clips if they are lost. Especially producer company may no longer have the interest to have it after how many decades.

Brake Pad Clips-clips

Though these are tiny compared to the whole body of the car you own, however, if you lose these until it has not been replaced your car will stay in your garage or in the shop for a long time. It’s better not to take the risk in driving than to have the courage and be regretful for either yourself or others be the victim of such a consequential accident.

 

Brake Pad Clip Brands

There are a lot of brands that you can see on the internet. The following are just some of the brands that we can give as an example for us to orient ourselves.

Brake Rotors and Pads

What is a Brake Rotor?

A brake rotor is popularly known as a brake disc.  It is a shape or surface that is round and flat in appearance. As it is shown in the image below that fine flat surface is the disc. This rotor or disc spins with the wheel as the car moves forward and backward.

The function of a Disc

Brake rotors are a necessary component in the braking system that stops the vehicle. Brake rotors are what the vehicle’s brake pads clamp down on to stop the wheels from spinning. Brake rotors are just as important to stop the vehicle as the brake pads are.

Brake Rotors and Pads-disc brake

Brake disc/brake rotor

In a disc brake system, most vehicles have disc brakes only on the front wheels, though newer vehicles may have disc brakes on all four wheels.  A disc brake is a type of brake that uses calipers.  As it is shown above, the caliper is the one attached to the side of the disc. It is in the caliper that the brake pads are attached and the disc will be in between the pads. The caliper will squeeze the pair of pads against a disc or “rotor” to create friction.

How is it done? With disc brakes, the fluid from the master cylinder forces into a caliper where it presses against a piston. The piston squeezes two brake pads on a disc rotor attached to the wheel. This forces the wheel to slow down and stop

The Brake Pads

These pads are installed by pairs in the caliper. In between the pads is the brake disc.  When the inner pad is pushed by the piston both the pads will squeeze the disc to halt the car.

When to Replace Brake Pads?

It is not easy to determine when a brake pad is to be replaced. While other cars have exposed brake pads so you can easily see it if it’s replaceable or not, others need to be intentionally inspected by a technician. One way of calculating and determining when to replace a brake pad is the number of years you used your car and that depends on your way of driving.

Are you fond of driving fast that you have to use the brake every time and then?

Or, the road condition to where you are driving needs the braking every time you travel? Let’s say you drive uphill to downhill every day and vice versa. Or, you are driving in an offroad that sometimes it’s muddy?

These will determine how long your car’s brake pads can last. I know good brake pads can last up to five years or more.

To ensure your brake pads are in the expected condition you need to check it every two years. There’s nothing wrong if you are always on the safe side than to be regretful by being lenient about it.

Looking for parts that fit your car, it’s just around your corner you can find it through the websites and this is just one of them. Find here.

Thank you for reading this short and simple post. I found a helpful video and you can enjoy understanding how the disc system parts work together. You can watch it here.

Defective Link Shaft Symptoms

What is a Link Shaft?

Defective Link Shaft Symptoms-Link Shaft

 

So, today, we will talk about one particular shaft, and this is the upper suspension arm link shaft.

This part is the one that links the upper suspension arm to the body of the car.

It is a part of the steering suspension that turns up and down as the wheels move.

As you can see in the left image you have the upper suspension arm and the link shaft disassembled.

The link shaft has the bushing detached from the link shaft.  That single link shaft has bushings on both ends. those will serve as the nuts that will be tightened to secure the upper suspension arm.

As the car moves, the wheels bump up and down the link shaft turns up and down too. A time comes that the thread between the link shaft bushing and nut and the link shaft thread will be worn and it will not be fitted to each other.

When the threads are worn the link shaft will loosely move and produces a sound you will never believe that comes from that part.

In different brands, the bushing is a rubber, other than the threaded which serves as a nut. You can see in the image below.

Defective Link Shaft Symptoms-Upper Suspension ArmWhen that rubber bushing is deformed due to time and use of the car it should be replaced.

Symptom

The symptom is just a sound. You will usually notice it when you drive on a rough road.  When the car bounces up and down particularly the front wheels, you will hear a loud knock sound under your car. This is more obvious in the kind of shaft above, which the bushing is the nut itself.

Bad Effect

This is not so much a consequential accident but when the defect is severe maybe you cannot tolerate it as you go along your way because it’s noisy and will hear that even in a smooth road.

Shaft Replacement

Bring your car to the shop and be inspected.  When the mechanic will tell you that it should be replaced, it should be replaced. Unless you enjoy hearing the noise as you go every day on your journey.

There are brands which we can choose from.  In my country, we have the 555 brand and the GMB brand. They are both from Japan. For other brands, you can find them from any manufacturer and dealers.

The link shaft holds an important role in the suspension steering system. The link shaft rod, the bushing. They may be a rubber or steel they both have a time limit of use.  When that time comes they will complain and you will hear that through a sound. 

When you can still ignore it then no problem but if you can no longer ignore find a time for them to be replaced.

Defective Ball Joint Symptoms

What is a Ball Joint?

A ball joint is a component of your car’s suspension and steering.  It is that connects the upper and lower arm suspension to the steering knuckle.

The function of a ball joint is to serve as the pivot of the steering knuckles where the wheels are attached through the spindle.

Defective Ball Joint Symptoms-555 ball joint

The steering knuckles are where the spindle is attached shown in the image below. That flat round part is the spindle where the four studs are inserted.

Defective Ball Joint Symptom

Have you experienced that your front wheels move more than what your steering control does?

When you feel there is more movement than what you can control over your front wheels especially when you turn right and left along the road.  There is somewhat a sudden sway of your front wheels more than your steering wheels can hold, that is a defective ball joint symptom.

When just one of the front wheels’ ball joints is defective it is not obvious.  The other wheel can hold the movement coming from the other wheel. But when both left and right ball joints are no longer working normally, definitely it will be obviously felt and you may wonder why as if your car wants to dance as you proceed along the road.

In slow speed, you can control whatever circumstance it may bring but when more speed is exerted the riskier your situation inside your car will be. It is not a thing that you should ignore but it is a thing that you should fix immediately.

 

Defective Ball Joint Symptoms-defective ball joint

The Result of a Defective Ball Joint (s)

Because you cannot determine when the extra movement of front wheels come, and you cannot control it, this will cause an accident not only to you but even to other motorists that will coincidentally be on the counter lane.

That little movement from the ball joints will enormously bring a derailment of the car from its proper lane and may hit another car coming from the other lane.

Or when either the ball joints can no longer serve the purpose the wheels will freely flip.

Defective Ball Joint Symptoms-defective ball joint accident

Life is Precious

So why ignore it when you have already noticed something beyond what your steering wheel controls. It is better to be cautious than to be regretful. The safer the better and you can save not only your life but your money that would be used for hospitalization.

Replace your ball joints with the proper brands that will endure the road challenges. The better brand the more secure, the calmer you are.

You can go online and see different suppliers for different brands of what you need. Explore the cheapest one but a brand that you can rely on.

Overheating Engine-Freewheeling Radiator Fan

Have you seen a freewheeling radiator fan?

Radiator fan or cooling fan is a part of the cooling system of an engine. It is attached to the front of the engine facing the radiator to cool it whenever the engine starts and the car is used on a trip or a journey.

The radiator fan blade is not fixed like other fans such as electric fans. It’s neither like the processor fan of a computer that is too loose. The story below tells you more about this for you to understand in case you still don’t, why a radiator fan is designed in such a way that it can turn left and right but not too loose.

It was far from my own belief that this situation has been the long-lurking issue of engine overheating since the engine was overhauled.

Nobody of us noticed that this radiator fan is no longer working efficiently and posed us to wonder for several months.

Until just this week we happened to discover because we were trying to analyze if the water pump is working. As we were contemplating my assistant happens to touch and move the radiator fan, and there it’s freewheeling. Please see the video below.

 
In normal condition, the radiator fan should not rotate freely. It should hold the fan blades quite stiff but not permanently. It should rotate both clockwise and counter-clockwise but not too loose.

Because this radiator fan is freely turning left and right when the engine runs the radiator fan blades will not rotate to the maximum speed to cool the radiator. The result would be engine overheating even in highways and smooth roads. The more the engine overheats when rev is exerted to climb uphill.

That was the case so we have to restore this failing radiator fan. Please watch how it was disassembled.

So it was disassembled and cleaned and refilled with silicon oil. It is not so complicated it is easy to disassemble and clean.

What tools and materials you need to restore this model are a 10 mm socket wrench, a Philip screwdriver, an impact driver, and a silicon oil-four pieces of the size shown in the picture.

Overheating Engine-Free Wheeling Radiator Fan-10mm socketOverheating Engine-Free Wheeling Radiator Fan-Impact drive

Overheating Engine-Free Wheeling Radiator Fan-Philip Screw Driver

Overheating Engine-Free Wheeling Radiator Fan-Silicon oil

 
As you see it in the video the fan blades are no longer freewheeling.  The silicon oil holds it but not so firmly and not too loose so that when the engine runs the cooling fan rotates.

Why is the Cooling Fan Not Fixated?

The purpose of that design is to give flexibility to the fan blades so that when something hard is accidentally inserted when the engine is running it will not be forcibly broken.

As the hard object is still there and the engine continues to run the fan blades will stop without being broken and you will have the time to remove that hard object.

No engine breakage, no cooling fan breakage too and the journey continue.

If you are sure your cooling fan cannot be rebuilt go to the alternative ones. Have them here.
