I am a new to this, so this may be a stupid question. In my '86 2.5L automatic Comanche, when I pull the lever into 4 hi, my back wheels do not turn. I was wondering if all 4 should turn? The truck runs and drives fine when switched into 4 wheel drive, but the rear 2 wheels just don't turn. I have a couple leaks coming from some where? If there is a problem, could the leaks have something to do with it?

What do I need for cold air intake for my 86 comanche? I have no power, and Advance Auto and O'reilly's have been no help. I've been looking for weeks.

I am also on jeepforum.com but haven't found an answer to my intake question. You seem to have it. How do I get a intake for my 86 mj? details please

I just got a 1986 Comanche with 109,000 for free because I did an even trade with my old motorcycle. What would be some good maintenance/tune-up tasks to do first? It does seem to run decently....

Where can I find a fuel tank sending unit for my 4x4 1986 mj 2.5L?
