this might be old news but I am going to post it anyways. I had the creaking rearend when going up drive ways or any other small inclines, so I took it to the dealer. the next day they called me and said that they needed to keep it for a few days because the rear end needed to be welded in certain places and that torqing the bolts in the rear suspension would not do the trick. has anyone else had this procedure done to thier car or did they just give you the runaround.
