Can anyone explain this?
 

Control Arm Polyurethane Bushings
Camber is the inward or outward tilt of the front tires as viewed from the front. Inward tilt is negative, outward tilt is positive. Camber is used to distribute load across the entire http://www.jackit.com/bushings/image...anation_sm.jpgtread. Improper camber makes the tire wear on one edge, and causes the vehicle to pull to the side that has the most positive camber. Control arm bushings can help correct your camber angle--but usually up to only 2 degrees.


I thought control arms only hold the axle in place, how would control arm bushings affect the tilting of the wheels (Camber)?

Not sure where the write up about Poly bushings came from, but it doesn't sound right to me. If you figure it out let us know. The only way I can think of that it could affect camber would be to crank in so much caster the the angle of the knuckles would rotate enough to change the camber. That said, I think your caster would have to be totally screwed to get 2 degrees of camber adjustment. I just don't get it.

that write up is meant for a Wish Bone set up like on a car. The wishbones are also referred to as control arms. This does not apply to a jeep. The only way to set chamber on a solid/live axle is to get adjustable ball joint. You can only set pinion angle and toe in/toe out. That is why we can do an allignment in the driveway haha

some much for them being "suspension experts"....

as stated. this does not apply to XJs, obviously, no body bushings as well.
