Late 80's Jeep question for a friend:
 

Got a question about a friend's late 80's Wrangler. Can't shift into 4wd due a vacuum line problem. If anyone knows what to look for it'd be appreciated. Or maybe there's a forum for this model Wrangler that you could direct me to. Thanks.

This forum's amazing. You post a technical question and within minutes people offer help. Thanks!

I saw this helpful attitude when offroading as well. Someone broke down in the mud pit and instantly it was pulled out, people swarmed the Chevy and got it to fire up after we cleaned the starter wires.
