And there you go.
Rear diff replaced. Whine gone.
So how long is the powertrain warrantee beyond the bumper-bumper on these differentials?
Has anyone successfully gotten GM to buy their car back under the lemon law for this problem?
An additional year, I believe.Originally Posted by PNBLWZD
Thanks. Yeah just doing some research looks like 5yr/100k miles. I started noticing some noise from the dif when the car is cold and going around corners, looks like I'll be visiting my dealership Monday to use that powertrain warrantee.
I apologize that you are hearing the same noise when the car is cold and when going around corners. If you wanted to private message me your VIN and mileage, I could give you the exact dates of your warranty coverage. Please keep us updated on the visit to the dealership tomorrow. Thank you very much for your time.

Put me down for one. Took my Sedan in on Friday with the wah-wah-wah blues. 2 minute ride with tech and he said sounds like the diff. Three hours later...Parts ordered for replacement later this week. Frustrating!
cadzilla32: Does yours make noise cold, when turning, or all the time?
All the time. Sounded like a brake pad rubbing at first but after a couple of weeks I knew it had to be something more serious.
New diff installed yesterday. No noise now! Question: is there a recommended break-in procedure for the new rearend? I am a Manual Sedan. Thanks!
