Message: <blockquote data-quote="jej1" data-source="post: 2437658" data-attributes="member: 314788">Only after 15+ miles of freeway driving and only when turning, I hear a groaning / whining noise from the rear end of my car.  I can only hear it when I make slow speed turns, like in a parking lot.The car is RWD, auto, with a posi rear end.Does this sound like the posi unit is toast?  Is there something I should try to fix it or should I just swap in a new third member? Is there anything else this could be?  Would a bad axle bearing sound like that?Thanks!</blockquote>
