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.
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.
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.
