    Seems like there is a lot spread out info on SUA swaps. I was thinking maybe everyone that has done SUA could post up their swap info? Axle used, springs used, shocks used, Pitman arm used, steering set up, driveshaft, etc.... Maybe we can gather this info in one thread for everyone to find and know it would help me as I am gathering all the necessary parts to complete a SUA swap using a waggy axle. I am looking to use:

    Axle: '88 Grand wagoneer D44
    Springs: Rancho RS44044 and Bonney kit
    Pitman arm: ??
    Steering: diy crossover kit from complete offroad
    Shock towers: tube shock hoops
    Driveshaft: hopefully stock like Xterror04
    Shocks: bilstein 33-185552 10" travel

    not completely sure but I think your using the wrong acronym in your thread.

    SUA means Spring Under Axle.

    I think your looking for information to complete a SAS ( Solid Axle Swap) for the front end.

    I just finished a SUA solid axle swap. I have yet to modify the transmission crossmember but I plan to run the stock X driveshaft. Once I removed the differential side flange it bolts right up to a 1310 yoke no problem. The only thing that could be an issue is if you push the axle forward it might need to be extended which will more than likely be the case for my build. The axle I got already had a high steer kit on it so I am running that to allow a flat draglink and I will have plenty of space to get over 4" of bump before running into issues with the steering contacting the frame. This allows me to have little to no bump steer. In your case with the kit you listed I would see no issue running it with the stock pitman arm(You will have to either ream out the pitman arm to the taper of the TRE's or use a tapered sleeve) you will just have a greater drag link angle and thus more bump steer, to mitigate this as much as possible I would make sure to run the tie rod over the knuckle to keep the angle as shallow as possible. Your height will then be your variable changing your angle. Many people in the jeep world run with a bit of an angle but the flatter the better. I will be doing a write up on what I did for the SUA leaf spring SAS in the next week or two as I have not been able to find any good photos of a leaf spring SAS on an X.
