So I did the cad delete and I put axle shafts out of a 2000xj into my 1990 xj. I capped the vacuum lines where they plugging into the old disco assembly on the axle. The problem I'm having is that the transfer case isn't engaging rite. If I pull the 4x4 selector lever it will go into position fine sometimes. Other times it will not go up past 4hi. It seems like Maybe a linkage issue? Also when it does go into 4lo right away it doesn't engage the front wheels. Any input helps thanks

 

The transfer case is shifted by the lever only.

How are your motor and trans mounts?

Ever see these?

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. The suggestions in CAPS are mine.

"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, 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".

TO SHIFT OUT OF 4L, SHIFT THE TRANSMISSION INTO NEUTRAL WITH THE VEHICLE STOPPED, SHIFT THE TRANSFER CASE LEVER TO 2H, THEN THE TRANS TO D IF YOU HAVE AN AUTOMATIC, OR INTO FIRST GEAR WITH A MANUAL, AND CONTINUE ON.

I did the linkage adjustment today and I think that did the trick thanks for the input.

 

How did the mounts look?
