New to the Jeep Community and Jeep Forums and need some help, btw not sure if this thread is in the correct spot

Jeep JK unlimited

—First I got this installed
JKS J-Venture 3.5” lift kit w/fox adventure shocks
JKS front & rear fixed length lower control arms
JKS front and rear track bars
35” tires

Had bump steer and steering wobble, and also slight rattling in the rear suspesion that they can’t figure out, then I got these parts below installed to try and solve the issue and didnt really help much at all

JKS flip kit with bump stops
Synergy tie rod
Teraflex heavy duty ball joints
Fox steering stabilizer

Also had a suggestion to install a JKS rear track bar relocation bracket made for 2-6” lift kits from quadratec where I got all the parts but the shop said that would cause issues, so they didn’t install that, not sure what to do, any suggestions? Recommendations?

What is your front end alignment reading look like? Caster specifically.

I was actually curious to see the print out but they didn’t give me that when I got the car back, they did an alignment both times they had the car

I feel like you just need a few more lights and it will drive better.....

The biggest question is what is your caster. It should be around 5 degrees, too little and it will be unstable.
Toe also matters, it should be something like 0.20 toe in.
A flipped draglink requires a raise trackbar bracket to steer properly. The draglink and front trackbar need to be parallel. The flipped draglink should have come with a front trackbar bracket.
Geometry brackets would probably be better for what you want than the longer control arms.
While the rear trackbar bracket isn't going to fix steering issues, it should be installed. The lift came with one, you should not need to add one.

Steering wobble, especially at certain speeds, is usually a tire balance issue.
A rattle or noise is usually either something not properly tightened or something making contact with something else. You can cycle the suspension with the springs removed to see if anything makes contact that shouldn't.

It sounds like you are paying someone money to through parts at it to see if anything "fixes" it. I would take it to a shop that knows what they are doing.

Welcome to the Forum, from Cave Creek AZ.
One needs to ask them for a print out.

Yes the lift did come with a front trackbar and bracket, and yes it does feel like something in the rear suspension is making contact with something else

^^^ If it is really DW, and not just a shimmy, which are two different things, then it is almost always the Track Bar mounting bolt hole brackets, that are elongated causing it. The above Link to Forum, has excellent videos that will help you through this issue.
