It's exactly how it sounds. When you hit a good bump in the road, your steering wheel jars.

This is mainly due to the drag link and track bar not being parallel to each other. When they are parallel, they move in the same plane and there is no ill effects.

No problem.

People who experience bump steer usually installed either a drop trackbar bracket or a drop pitman arm along with a lift, that was unnecessary.

im not entirely sure...i just replaced the bushings in my rear sway bar that was VERY loose...not its tightened up but there is just a little sway left...it seems to come from the steering...like the wind is blowing...but not as bad as it was and usually only when i decelerate...

As AxTJ asked above but you did not answer, has your TJ had an alignment recently? If the toe-in and/or caster angles are far enough off, mushy sloppy steering can result.

yes it was aligned recently about 2 weeks ago. i think the rest will be cleared when i change the drop pitman arm. Replacing the bushings on the rear stabilizer bar greatly helped the overall sway, but there is that little bit left...i think killing the DPA will finish it off. I am working out of town so its hard to find time to work on it. I have a pitman arm puller so it shouldent be too bad...but i have never done that before.

Sorry to butt in, but I am in the process of changing bushings on the suspension trail arms, track bars, both for front and rear, any advice on how to remove those bushings, need a press? need the bushing tool listed in the manual?

Thanks

Hahahaha I hate bushings...I just pulled the old ones out with channel locks and to get the new ones in takes alot of grease/oil and patience...I used a vice and a hammer. Haha just make sure you clean the corrosion out it will make it a tad easier...
