I have a 95 xj. It takes an act of congress to get this thing to go in and out of 4wd. Its not the linkage Its been checked. When I do get it into 4wd it keeps poppingback out. Then I can't get it back into 2wd. Any thoughts?

 

Is the XJ lifted? and do your tire sizes match? How did you check the linkage?

 

Shift linkage adjustment, imo.

 

It's lifted 4 inches. All tires match. It was checked on a lift by a local mechanic that knows his sh@t.

 

Sounds like the TC is damaged.

 

Try this:
Here's how the factory suggests you shift the transfer case and I've been doing this since these things were new and I worked at the dealership. Quoted from the owner's manual.

"To engage, shift the transfer case lever from 2H to 4H while the vehicle is moving at any legal speed". I let off the gas, throw the lever and then tap the gas and let off.

4L position: " To engage, slow the vehicle to 2-3 MPH , shift the transmission to Neutral, then shift the transfer lever to the right and pull firmly rearward to 4L".
