whine

    Whine from rear. Rear end or driveshaft?

    My 2008 GMC Yukon has a noticeable whine coming from the rear, under acceleration at highway speeds. I cant tell if it is a rear end problem or a driveshaft u-joint. Any suggestions on what to check? Thanks! By the way, it's not coming from my wife complaining about my driving.:laughing1:
