Hi guys im new to the forum first post hope is in the right section lol. Just installed a 4.5 lift on my 88xj and took it to get aligned and has negative camber on driver side tire -1.8 I was reading it could be ball joints or bent axle but just wanted to know if this can cause that camber. Also before i installed my mew lift and tires, the old driver side tire was worn real bad.

 

There was an issue back in those days with front axles jigged wrong from the factory resulting in the issue you describe. If the ball joints are bad, I'm sure the alignment guy would have pointed that out id he was worth a hoot.

There are adjustable ball joints available to address this issue.
