Ok, here’s more :
That Jeep isn’t tracking is what you are describing.
That looks like a rough country track bar , I have one and the bushings are junk..,you need to knock them out and get replacements at o Reilly’s , under 20 bucks each. The rough country bushings have way too much flex .
Next dry test it for anything loose, even minutely. Lay under it and have someone rock the wheel , anything that moves NEEDS TO BE EQUALLY MOVING WHAT ITS ATTACHED TO. This is true up to the track bar , it’s job is to maintain axle center in motion and should not visibly move much at its mount points .
Caster is likely out , you need 6 + degrees , you can check in your yard with a Swanson magnetic angle finder . Printout will show.
Get your tire pressure down to 26 psi, yours look high .
Now raise the hood and pull the coolant jug and check the steering shaft u joints for slop..trust me, this can cause you grief.
Now stand back and see if the axles are aligned and centered , and see if the right tire to tire distance is the same as the left.
TJ’s are very simple in steering design , but they have a small wheelbase , horrible aerodynamics,,usually oversized tires , are relatively light , and will quickly tell you if they think they have been touched inappropriately.
They aren’t hard to get right , just easy to mess up.
Thanks, I’ll look into all those. Do you happen to have the p/n for the new bushings for the track bar?
