ive searched for the past few days for some kind of write up on a wj steering box swap into an xj, but havent had any luck. can anyone point me in the right direction? TIA
There are a number of posts in various threads that discuss and show pictures of the WJ box swap.
I've made the swap myself. It does require a significant amount frame destruction and re-fab.
Search Advanced Fabrication for "wj steering", and specify posts by "XJBUBBA". This should net you 5 or 6 threads that discuss the install of the WJ box.
They will give you insight to the difficulty.
People choose the WJ box if they are trying to gain more room for a wider radiator. I believe the Durango box is similar to the XJ box, in that it mounts inside the frame, versus on top.
