Diff Rumble

I have a rumble coming from the rear of the vehicle when I turn.
It does it more on left turns than right and you have to be turning on dry roads.
It only does it when torque is being applied (gas petal depressed).

I think my rear diff is the source. If so, what action needs to be taken to fix it? Anyone with a similar issue in the past/present?

Thanks,
Billy

Could be a wheel bearing, drive shaft joint or differential problem. I would drain your diff. and see what comes out.

Is yours equipped with a Limited Slip?

Your first action should be to drain the fluid, inspect for particulate matter and replace the fluid. If you have a LS make sure your either use the appropriate amount of friction modifier or use a gear oil that already has it in it, such as, Royal Purple.
