No drop pitman. 2.5 Old Man Emu lift. JKS adj. TB. Everything else as far as steering goes is stock.

Was in the process of saving up for adj control arms as well as upgraded steering components and want get this little wobble under control.

caster could be a problem. have you had it aligned to see what the specs are? if so, post them up.

Here's a discussion on measuring caster. I run 6.5 caster with 33s on the OME lift, set using adjustable upper and lower control arms.

The JKS front track bar will hit the tie-rod or the diff cover, depending on the generation of bar, without 2" front bumpstop extensions. So that isn't helping your situation at all. You need to rectify that situation. Here's a summary on the clearance issues. Here's how I set up my front track bar at full bump with a V8 ZJ tie-rod and 1.375" front bumpstop extensions.

while we're on the subject, you also need to check the rear track bar clearances. I ran into some major issues back there as well, here's a summary on that. You may find reading through my build thread useful since I've already worked through these bugs....

In my opinion that's the problem with mine. Then again I have factory control arms. Do you have aftermarket control arms? Adjustable or fixed?

Mostly everyone I have seen that is complaining about wandering on the road has had our same setup. Which is "x" amount of lift with stock control arms. So I belive they have everything to do with our jeeps wandering.

If your camber is 4.6, you've got some serious problems... IMO

caster. Don't know how that got in there. I have zero problems anymore. Adjustable arms are on the to do list but it's driving fine for now.

caster does involve some personal preferences around drive-ability.... just because you like 4.6 caster, doesn't mean everyone else does.

I started at 4.5 and eventually moved to 6.5 caster in 0.5 increments, with 33s, and I very much prefer 6.5. 4.5 was scary by comparison. Jeep wandered all over lanes and followed every little defect in the road, plus return to center sucked...needed two hands on the wheel and a butt clinching the seat @ 65mph. With 6.5, I can hold one hand on the wheel @ 80mph.

I don't like my caster... I'm simply stating that I had massive steering issues before and explaining what I did to stop them. I don't have good return to center now, but I can hold one hand on the wheel at 80mph as well. Not recommending 4.6 caster to anyone. Simply stating that if the OP has issues other than his caster there are things he can do to improve his situation.

I don't believe I do have other issues than my caster. I self checked the Toe and it was correct according to my Internet finding. I've done a dry steer test and ball joints and bushings look good. I don't have a drop pitman arm. - (To my knowledge)
My brother in law who is a diesel mechanic has been dumb founded with it also. So with a little research I truly believe my culprit is my caster. How do I check my caster angle myself?

It is nearly impossible to get an accurate (!) caster angle on your own. Take it to an alignment shop for that particular angle measurement.

Oh c'mon Jerry... you can pick up a Hunter Alignment Quick Check Machine for about $21K
