I bought this unit used from a fellow with a Mustang who had it in his car but ended up pulling it for an E - locker for manual lock control . This diff is in great shape . Auburn makes a very solid LSD that will take a beating and not wear out for a long time .
According to the above context, answer the following question.
What is the narrator inspecting ?
