A gear shop should have the correct tools to pull bearings without ruining them, like the Yukon clamshell puller. Even then they can get screwed up. I probably wouldn’t have used another set of bearings for warranty work being done this soon. I would have just inspected them for over heating, discoloration or visible damage.
They would only have to pull the pinion bearings (races stay in the housing) so they are most likely the same ones which is fine but any new gear set could have small differences in tolerance from the other so always good to check which I’m sure they did.
We use the same puller and though they work great, they aren’t perfect and sometimes cause damage to the cage, especially on odd sized bearings. That would of course mean replacing it. But yes on inspecting them for hot spots, for sure.
awesome info. I called a local shop that does race car drivetrains and spoke to the owner. He referred me back to my shop and even dropped the shop managers name. I think that with what you guys explained and he told me about ECGS I just need to let them check it again. Is there any direction I should push them in like “more preload” or “less shim”?
The shop is willing to work with you so see what there plan is. I’m sure they will take a look at things again and get it fixed. No need to add or change shims unless it needs it.
^^^^ this
It is great that you got this figured out, and the shop was dedicated to your satisfaction.
wow! so that may have been the issue all along.
