Wouldn't hurt to try some limited slip additive before you yank it apart. Just go to your local auto parts store and ask for limited slip additive. It's a pretty small bottle. O'Reilley's, Autozone, NAPA, all have it around me. Costs about $5-6 a bottle. If that don't do it you've got a spool or a Lincoln locker (welded spider gears)
