My front Dana 44 axle seems to be in locked-in mode (2003 TJ Rubicon). Jeep is on the rack, no compressor attached to diff hose, and both wheels spin forward together. Hooked up my Mighty-Vac & can actuate rear locker but no unlocking (deactivating) in front (still locked in). I know they lock in with about 4psi. Jeep was in an accident & struck in left front corner. Upper & lower control arm replaced. Getting ready to pull the diff cover & unsure what to look for when I get in there. So I'm reaching out to the group again for some insight.
