Has anyone had their rear diff replaced? Jeez, I thought it was a simple fluid change.

When I took my Camaro for the groan, they told me they were going to do the flush. Thankfully it fixed the problem! My service advisor told me the only time they would need to swap the diff would be if the groan doesn’t go away after 3-4 flush/fluid swaps. Never heard of a dealer jumping into the replacement right away.
