ok...Mike B. have you driven this Jeep?
Not yet, But I know the Jeep
That's what I was thinking, check the caster. Also, have them set the toe in higher than your typical car. around .125 and see if it works any better.
Caster could help the cause, Not sure how much with the wandering.
i just payed 50 bucks last friday to have it alined. ppl say there pretty good at alinments. and yes i have a drop pitman arm. he told me my cater and all that was good.
Mine has a tenancy to do this, I do all my own alignments due to my setup, Not sure a shop would have a clue how to work on it. But mine does it because I am not running enough tow in I need to set it to about 1/4 inch. Just don't drive it on the road enough to remind me to change it.
Someone said bump steer, I would say this is what you having. When the suspension moves up and down, the steering follows if the swing of the track bar is not equal to the swing of the drag link it will force the jeep to drift left or right depending on which way its moving. So any change in the road could cause it. It has stock steering and a stock track bar right? He replaced some of the steering but not the way its set up.
Maybe this will help
Notice the very narrow range that the two arcs are parallel with each other. This is the only point where the drag link and the trac-bar are the same length resulting in limited to no bump steer. The further the suspension cycles on the vertical the greater the bump steer due to the differences in the arcs
With the drag link and trac-bar being nearly parallel the arcs of movement have a broader range of continuity and thus a greater range of movement with no or limited bump steer. The drawing does show them nearly horizontal which rarely happens on vehicles but for example purposes it is the best way to represent the set-up.
Lifted Jeeps
The drawing to the above illustrates a trac-bar and drag link set-up on a lifted vehicle. Notice the very uneven angles between the two creating severe bump steer.
The drawing to the above illustrates the same set-up but with a trac-bar relocation bracket and a dropped Pitman arm. The two bars are now closer to being parallel than they were before.
And when the suspension moves its going to move the steering, The track bar is fixed and the drag link is hooked to the steering wheel which has give in it. Hope it makes sense.
