I did just take my Z to service. All bushings are changed to polyurethane.

Rear end/wheels started jumping last summer when I do Â´pedal to metalÂ´ with 1th gear. Car has been driven 121000km and its -90.

Got right rear bearings replaced under warranty two months ago. Now, the same wheel is making the same noise again. The guy who did this work said he'd replace it again but wants me to take it to a dealership to find out if something else is causing the bearings to go bad. Any suggestions? The car hasn't been abused so why would the right rear go bad three times in less than a year while the left one is fine? Was it installed properly? I'm getting tired of having this same issue over and over again!!!! He did mention that he'd put in aftermarket hub assembly and when he talked to a chevy dealer on the phone, he responded that he would replace again with OEM if necessary, still under warranty.

Is the bearing really going "bad" or do you have a u-joint that needs help?
If the bearing has some vertical or horizontal play - an 1/8" or more at the tire face - then it should be replaced. Or maybe you connected with a bad batch of bearings; best to use the AC Delco OEM ones.

I had bad u-joints causing squeeking in my rear end and I suspected everything but that.
