Your thoughts please...
Problem:
very loud pop after reverse is engaged; pop when performing a tight turn into a parking lot
Background:
94 LS; transmission rebuilt summer 2006; no tcu lights/codes; minimal rear fluid leakage in driveway
Options:
1. install a used rear differential myself (availability - cost?)
2. rebuild the current rear differential by a shop or myself (likely needed parts?)
Suggestions:
Any suggestions that would enable the repair at minimal cost are solicited and greatly appreciated.

THANKS

Jeff
