I'll trade ya for the XJ,
rides fine up to about 110, then I get a few vibes from the rear drive line angle(soon to be fixed)
I am sure it would be a fair trade
hope you figure it out.
when I got my jeep, the right knuckle to tie rod was ovaled, all the ends were bad, with crappy ball joints and bearings, and she was still smooth on the highway in the front end, slower speeds sucked.
