I've recently had my cv half shafts replaced on my 07

Customer Question

I've recently had my cv half shafts replaced on my 07 spectra ex standard Trans, and I believe they may have damage my Trans out bearings, with the OEM shafts they only moved about .020-.025" at the Trans end, and now they are moving a good .06-.075" and I watched them removing the old shafts by prying against the trans housing. And I'm thinking that the forces they were applying might have damaged the bearing/race. Also it has started leaking gear oil. It's getting pretty annoying, I've taken it back in twice to get it fixed and it's gotten worse in both occasions. Now any time I hit a bump at relatively low speed I hear it clunking around and grinding. I've checked the hub knuckle bearings and they seem to be just fine, so I'm looking for a second opinion of sorts. Would you come to the same conclusion as I did in thinking that they damaged the bearings by removing the shafts like that, and would those be a possible explanation for the nosie and grinding?

It would be very hard to near impossible to damage the differential bearings and pinion gears which support the axle shafts. Often prying and hammering is needed to get the stubborn things to pop out. Cutting a seal upon installation is very easy to occur. It sounds like to me the shafts are possibly aftermarket and are not to the same tolerance and to blame for these issues.
