2002 Pontiac Trans Am V8 Two Wheel Drive Automatic 91000 miles
I recently purchased this car and knew it had bad wheel bearings. I figured that while I was replacing the wheel bearings I might as well go ahead and replace the carrier and pinion bearings as well. I replaced all bearings and re-assembled everything to specs as best I could. I took the car for a test drive and as long as I give it gas it is fine but when I coast I hear a whinning noise from the gear set. I had.008 backlash on the ring gear and thought this may be too much so I went to.005 and still had same noise. Got any ideas on what this may be? Would like an answer by someone who is a reputable mechanic who knows rearends please.
