Im running a set of 3" RC coils and 1.5" spacers under the front of my xj and I have the stock track bar with one of those axle side relocators. I am 98% bumpsteer free except for speed bumps going slow. It drives and tracks straight, no pulling over the road

 

The new alignment machines arent set up to do toe only. They have to have all 4 heads installed, head compensation done and a caster sweep. The name of a front adjustment is call thrust angle alignment. Aligns front to the rear for propper tracking and centering of steering wheel. Low caster will cause a wander due to steering return being low and tires not "chasing" a point far enough in front of the vehicle. Caster is factory adjustable to a point on xj's. Camber also is with offset upper ball joints or offset lower castle inserts where bal joint stud goes through the lower knuckle. Best caster adustment is adjustable lower arms. And a good alignment shop can do either. Find a shop that has lifted vehicles that the employees drive daily to do the work. But short answer aligment can cause wandering.

 

Im having bad wandering with curves in the road.

 

got the Pro Comp lower control arms installed, and the alignment done by 4WP today... Tracks great and no wandering!

the new lca's were about an inch longer than the factory ones, not sure if that did the trick, or the alignment did, but I am a happy camper now!

 

I have had my Zone 3" for a month now set the toe . It's good but it is kind of twitchy @ highway speed . I came across a set of pro comp arms for 20 just need bushings .

 

Replaced my track bar .... No issues anymore even left the sway bar links off !!
