2000 Sport with the 32rh trans (145k miles)- had that rebuilt Dec 2020 - last 3-4 weeks Jeep has been sluggish accelerating , knocking sound when accelerating from stop, trouble getting out of 1st gear. Thought it might be trans - took to shop under warranty they said it’s ok.
Checked rear differential (don’t use 4wd / doesn’t work rn) And oil came out tar black , with some glitter - am I hosed? What can I do , would it be ok to clean up - replace gear oil and put cover back on and see? Or is it time for earlier than expected regear. Should I check the front as well ? I don’t think the diff fluid has ever been changed.
