Default Bump steer

Hi y’all, I’m trying to figure my bump steer problem I currently have a 3.5 lift on my 09 wrangler. I’m trying to figure out to make my drag link and track bar parallel should I remove my raised track bar bracket and put it back to the stock location? I will post some pics also thanks for any advice!

The raised track bar bracket as you can see it’s not parallel with the drag link

You need to move both bars, or neither. If you want to keep the bracket, flip the draglink - or add a less desirable drop pitman. There are options that have you drill out the knuckle, and others that do not require drilling, but either choice would be a better call than a drop.

I put back my stock pitman arm back on and it helped with the bump steer so you’re saying if I remove the bracket it will get worse?

That seems odd. No idea why your steering is better after removing the drop pitman, considering the current interesting angles with just the trackbar bracket.

Typically, you'll see:

Both in stock location (parallel, but steep)
-or-
Trackbar bracket + Drop Pitman to lower draglink from frame (parallel and flat)
-or-
Trackbar bracket + axle end of draglink raised to top of knuckle (parallel and flat)
-not-
Bracket + stock pitman -or- no bracket + flipped to top of knuckle . (neither parallel nor flat)

Theoretically, that last choice should be the worst handling, but you indicate it is better?


Quite a few people have posted negative experiences with drop pitmans. They were all talked into going back to stock pitman and then Flipping the draglink to the top of the knuckle instead.
Maybe you'll just have to experiment: remove the bracket and see how it handles, if it's still not what you want, then look at using the bracket and flipping the axle end of the draglink up onto the top of the knuckle instead.

I just removed the bracket today and it handles much better actually the bump steer is minimal handles as good as it was stock to be honest.

I added positive caster after my 2.5-3" lift and eliminated the bumpsteer. Have you got the caster correction back to factory specs done?
