Full hydro is the easiest option when doing a flexy 4 link setup and will reduce bump steer. triangulated 4 link will have a vertical movement path with a small front/rear arc due to the links.
the current setup, parallel 4 link with panhard, not only has a front/rear arc but side to side due to the panhard. this lets you use th efactory style steering with little bump steer.
while Hydro is the Most common and easiest, it is not the only solution. take more time and fab, but you can run manual steering with 4 link and eliminate most bump steer. just gotta get creative.
otherwise. are you going for single or double triangulated? single maybe be easier if you triangulate only the lowers, double would be hard due to the oil pan and short wheel base of the XJ.
