I don't have links, but two items I've read about the True-Trac Torsen type differentials; yu have to switch to the green type axle bearing. That and there was supposed to be an article in one of the Mopar mags about retaining the original taper bearings when switching to a True-Trac. I know I don't have the issue and haven't had time to dig it up. Just FYI, the search may be worth it to you.
