94 MU 4WD problems

Postby JollyOllie » Tue Jun 21, 2022 4:53 pm

Hey, I've got a 1994 MU, I recently took her on a trip and during this the 4WD stopped engaging. It's constant hubs so they aren't a problem. Jacked up the front wheel and everything spins up through the front driveshaft, my best guess is either the transfer case or a solenoid. Went throught some deep water so maybe buggered a wire or a vac line? Any info would be appreciated. Cheers

Did you do this to both wheels? Is it factory with the disconecting diff or have you just installed the drive pl;ates from the later model instead of free wheel hubs?

Yeah I did it to both wheels, the left one had trouble engaging at the transfer case, everything up to there spun as far as I could tell.
Everything is factory as far as I know.

Sounds like you have verified the diff hubs etc. Are you sure you are selecting 4wd on the lever?
