Diff Rumble
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
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.
