OK, so i just had my rear end worked on by the dealership, its the stock 10 bolt and it was whining at about 60. the dealer put in a new gear set and all is good, no whining. but now, when i make left and right turns real slow, like pulling into a parking space or just doing slalom with sharp left and right turns at 20 - 25, i hear a whining/singing sound out of the rear. i cant figure it out, is this normal for new gears or did they not do someting right.
any thoughts?

thanks
