Question about 1988 Jeep Cherokee
1988 Jeep Cherokee 4 wheel drive not working. The drive shaft spins so it appears the vacuum actuated lock up isn't working. All vacuum lines are in place. How do we troubleshoot and locate the problem?
Ok so I'm having the same problem. My drive shaft spins but it doesn't really feel like I'm in 4x4 it jumps in 4low when u put it in drive but no matter what, the front tires won't spin, even in mud, they just sit there like I'm in 2 high. It's lifted and the vacuum lines are just hanging on the passenger side, I need an extension kit for them to reach. I'm new to this so Ill ask, do they lines HAVE to be hooked up for 4 wheel drive to work and if so do yall know where I could find an extension?

It sounds like the vacuum acuater is cracked or broken internaly. Recomend replacing the acuater and replacing all vacuum hoses at the same time. There is also a small relay switch under the hood under the radiator tank that may also require replacing.
