4 wheel drive isnt working
hey i just got my hub on the driver side fixed and i cleaned them up like the dealer told me and now they worked when i reinstalled them... now they arent working again. i dont know what i should look for, the hubs are run off of vacuum right? they just arent locking in. thank you for the help i will give any info to help further diagnosis.

If you have ESOF( button on the dash) then your hubs will say auto or locked. With the hubs turned to auto, then the hubs lock in off vacuum. If the hubs are turned to locked and the 4x4 works, but not in the auto mode, my guess would be you have a vacuum leak somewhere.

It could be a few things; hub seals, transf case, electrical relay, vacuum hose, vac relay, etc. I would do a search in here as there is a lot of info on it. I would service both hubs before diagnosing but I guess you did that.
