Jeep QuadraTrac help

doktorew · 05-06-2015, 02:44 PM

Hey all, new to the 4x4 world and hoping that someone local might be able to help me with my recently acquired 1978 Jeep Cherokee.

When I bought the Jeep, it came with the front drive shaft disconnected. I didn't think much of it at the time, but I've come to learn that is a bad thing for the QuadraTrac system.

I actually had it flat-bedded home, but I drove it for probably about 2 miles after I had a new brake master cylinder and exhaust installed. It eventually lost drive, and I had it towed back home. My understanding is that no front drive shaft will make it behave that way.

I'm not sure if the transfer case is toast at this point, but I'd like to at least hook up the QuadraTrac vacuum hoses to see if it will still run in Emergency Mode (from what I've read you can run without a front drive shaft in E-Mode without issue) and possibly install the front drive shaft to see if the 4WD works at all. I consider myself somewhat handy, but I think I might be in over my head trying to get this sorted. Does anyone know a shop well versed in older FSJs? I'd also be open to any forum members that might want to lend a helping hand, I have an excellent beer repayment system.

Any help on the matter would be greatly appreciated.

Thanks,
Drew
