Bearing damage

Post by Arbs » Mon Dec 18, 2023 10:58 am

I pulled my driver's side wheel to clean and grease the bearings and found the outer bearing with this chip. Everything was tight, no play in the bearing, or wheel/hub. Do you think this came from an impact while driving, or a different type of stress? Do you think I should look into a shim?

This bearing is about 1 year old, and appears to be in excellent condition except for that chip.

I haven't pulled the passenger side yet, but plan on doing that today or tomorrow.

Thanks all!
Where is the OBD2 port on this thing?

That's no problem at all.

Yup- just grease it and put it back together and go drive it.

Is it made in China or USA? If it is China I would use it until I could find a good used or new USA bearing and replace it.

I have never seen damage like that on a bearing ring. The damage might be from a heat treatment issue or from a metallurgy problem, such as carbon depletion aor dirty steel. Mishandling might cause this but it's doubtful in this case.

Use it until a good one is obtained.

The only cause for concern might be if that broken off piece is still in there somewhere, and it could be dislodged and go through the bearing. Closely check the retaining nut and the grease. If you can't find the piece, it must have been installed with that flaw.

I suspect that’s accidental left to right side crossthreading damage. I’m willing to bet the broken piece ended up being swept up in the garage and never made it as far as the hub.
