Hey guys anyone else having these diff problems?? I like many others had my differential replaced about 5900miles after hearing the annoying whining noise around 40-45mph. Lockhart Cadillac Indianapolis,IN replaced the differential after changing the fluid to see if that would help(it didn't). After getting the car back I was happy until about 300 miles later backing out of a parking place at low speed cranking the wheel I heard this grinding rubbing noise. After keeping the car three more days I should have the car back tomorrow with another new rear end. They say the clutch pack went out of the rear end? Oh well, they paid for it and they also installed my new sub-frame bushings...I can't wait to check out the wheel hop issue, but now I'm a little afraid to get on the rear end too much.
