Have an 08 JKU with a 4" Rancho Sport kit(dropped pitman arm), 37's, RS7000 Steering Stabilizer and decided to upgrade to a JKS track bar. Took off the trackbar drop bracket and stock trackbar. Measured the axle, installed the JKS trackbar, re-measured, torqued everything down and went on a test drive. Seemed to have developed some issues. The steering is VERY soft compared to the stock setup with the drop bracket, and somehow have developed bumpsteer. The steering wheel moves with acceleration, and moves over small bumps. No clue what could have caused this.. Any help would be appreciated before I take it to my guy at 4WP who runs the JKS on his jeep. Thanks everyone!

 

Track bar and drag link need to be as parallel to each other as possible....if not, bump steer results.

What does yours look like now with the new parts?

 

Here's what I'm working with

 

You need a stock pitman arm.

 

Guess it's a good thing mine's still sitting in the parts box. Thanks guys for your help!

 

Yep, the drop pitman and trackbar bracket work together to keep the steering angles good. Install one without the other, and you have issues. Remove one, and leave the other installed, and ...

At least it's an easy fix for you.

 

45 Minutes all done and said, gumbys back to rollin how he's supposed to. Thanks everyone for all your help! Thankfully i didn't get rid of my factory pitman or we would've had a bigger issue...

 

Excellent!! Glad you had the stock pitman arm.

Anyone think it'd be worth it to go ahead and beef up the rear?
