I can't speak to why the gear is not turning. You already have more experience with these lockers than I do by pulling and greasing yours.

Greetings from Douglasville.
96 3.4L 2wd silver. Plain old stock AFAIK with exception of wierd aftermarket wheels; apparently the PO made off with the OEMs via Craigslist.
Wow lots of people name their 4R 'Frank;' that can't be a coincidence.
I must be wierd as I named mine Mr. Hammond which is A) not a girl name and B) always pronounced with the Mister :crazy:
