    Smile Update on Differential whine

    My 2006 V-8 RWD now with 36, 255 miles seems to have the "whiney rear-end" fixed.
    After putting a new Driveshaft, total rebuild of the Differential, replaced leaking Axle Seal (not related to the whine) the GMPP warranty folks agreed to put in a NEW Differential. The job was completed Friday around 5 p.m.
    I drove it about 45 miles yesterday at speeds up to 70 mph and did not hear a thing.
    I really do like the vehicle and am so hoping that this fixed it. seems like it did.
    I am a happy driver.

    I was hoping it would be something simple and cheap, not something that would cost a few thousand dollars to fix. Congrats though!

    Re: Update on Differential whine

    Some advice from experience: a proper break-in is crucial!! I had the original and a replacement diff both whine after a few thousand miles in my '04 SRX. After some research, I found that a proper break-in period, with no aggressive and/or constant-speed driving, was a necessity. The third diff was quiet for many thousands of miles until traded for a new SRX. Hope your problem is now solved....good luck!

    Re: Update on Differential whine

    Thanks Kauai 1.
    I have put almost 200 miles on it.
    No aggressive moves, just normal driving in populated/freeway driving in Houston area.
    As mentioned, up to 70 mph and all speeds below.
    Once I hit passing gear to get a round a beemer trying to hold up the flow of traffic.
    I think he said "what was that". lol
