Threw my XJ back together last night. Massive improvement! No more white knuckle driving. The darty, twitchy steering are completely gone. No more surprise lane merge. Super tight & responsive steering, excellent return to center, stops & goes straight, go exactly where I steer it to. Tested good and smooth at +75 mph
95% sure it’s lane merge attempts were from binding ball joints (ball joints misaligned from bent inner C) and insufficient caster. I modified track bar frame side mount, to line up better with drag link and not to rub on tire on tight right turns.
Need to put in real bump stops. But for now I’ll just let drag link & track bar do it’s self clearancing on the oil pan
