I can't for the life of me figure out what my issue is with this. All front control arm bushings are perfect, newish steering box, ball joints in good shape, tie rod ends tight some new, track bar tight... but my buddy thinks its bent, but I'm pretty sure its fine. It has more bends then stock, it's a Rubicon express upgrade when I got my 3.5in superflex kit. Steering shock is perfect, and I just had an alignment.

What am I missing? Its pretty much only noticeable on highways. If the highway bends to the left, im fine, but if its a bend right, it feels like I'm a twitch away from swinging out of control! I can't figure this out!

Also, this has only started happening after I swapped my front diff... did I mess something up in the swap?

It was from a 95 zj, and went to a 93 zj

Sounds like either a bad tirerod end or out of alignment. I may be wrong.

Could be bad control arm bushings.

Check the rear track bar to see if the bolts at both ends are tight. When I first got my 95ZJ it felt goofy, kind of like the teacup ride at Disneyland. I found the right side of the rear track bar loose.
