boosted_Ok Posted March 13, 2010 Report Share Posted March 13, 2010 im looking to buy a camaro and i finaly found a z28 with a 6 speed and the only main problem im having is the rear end makes a whining noise?? owner said its been doing it and is common in trans am and camaro's.. im pretty sure its the pinion gear going bad but how long can it be driven like that and is this a pain to change? or expensive Quote Link to comment Share on other sites More sharing options...
MrMeanGreen Posted March 13, 2010 Report Share Posted March 13, 2010 That means they were trying to launch the shit outta it more likely, and it'll probably need gears. They run in the $150 range for gears, $100 for the install kit, and labor can vary. Quote Link to comment Share on other sites More sharing options...
Billiumss Posted March 13, 2010 Report Share Posted March 13, 2010 if the car itself is in good shape then just replace the rear guts for $500 when you get it. If your not going to race the car then this option would be fine, just use GM parts and you'll be quiet. 6 speed cars are known to have rear end issues since they get "shocked" more when launching.

Richard Cranium Posted March 13, 2010 Report Share Posted March 13, 2010 Mine did not whine until we installed the 4:10 Richmond gears. Apparently Richmond gears whine more than others. If yours are stock then might be worth it to replace them. Since it'll all be apart might be worth rebuilding the posi unit too (new clutches, etc...) Also could install a new rear end cover at the same time. I think I saw someone selling a 10 bolt cover on here, jegs brand if I remember correctly.

boosted_Ok Posted March 13, 2010 Author Report Share Posted March 13, 2010 all he told me was it was a constant whine under load... i havent looked at it myself but im new to all this.. im sure its a bad pinion bearing since i heard its a common issue in trans ams and camaro's...

Richard Cranium Posted March 13, 2010 Report Share Posted March 13, 2010 here is the thread with the cover, dunno if he still has it or not. But if your going to open the rear end anyhow this would be a nice little upgrade to make it stronger. http://www.columbusracing.com/forums/showthread.php?t=74908&highlight=jegs Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted March 13, 2010 Report Share Posted March 13, 2010 some gears just whine. i have had a few sets in my day that no matter how i set pinion depth, or side load, they whined a little.(im talking whine you could barely hear, only cause the car was quite) but it could be a bearing whine aswell. these are bad about the pinion bearings going to shit and causing a whine aswell. hell i have even seen fresh gear oil quiet some down. BUT! IMO if your going to drag race the thing and do hard lauch's with it, get away from the 10 bolt period. no sense in putting moneys in it when its just going to keep breaking the more you mod the car Quote Link to comment Share on other sites More sharing options...
gillbot Posted March 14, 2010 Report Share Posted March 14, 2010 get a used rear from the forums for $150-500 if you don't plan on racing it. Quote Link to comment Share on other sites More sharing options...
smokin5s Posted March 15, 2010 Report Share Posted March 15, 2010 +1 on replacing the rear... like James said, you can either get a used rear (make sure it's in good shape before buying... it might be for sale because someone trashed it) or save up and get a 9 inch.

Gears can whine, but the pinion bearings take more of a beating in an f-body. Quote Link to comment Share on other sites More sharing options...

I got mine used for $100 and had it rebuilt with stock 3.42's for $150. $250 for a completely overhauled stock 3.42 rear is pretty dam good imho.

Sully Posted March 16, 2010 Report Share Posted March 16, 2010 My car makes more of a grinding noise under load rather than a whine. I'm sure it's the pinion bearings. I replaced fluid. Still did it. Pulled both rear axles, had them checked for straightness (and they were), put new axle bearings and seals in. Still did it. I've been driving it like that for 3 years. I even took the car to Marion last summer and ran it 10 times in one night. Granted, I have street tires, so it didn't hook for shit. Irregardless, instead of dropping more cash on my rear (the car, not mine), I'm saving for a 9". But that's because I want to hit some track events. If I knew for sure that I wasn't going to race it anytime soon, then I'd just have the 10 bolt rebuilt. Quote Link to comment Share on other sites More sharing options...
