follow up on the lift, since it is a 2wd, the lift gets it to the height of a leveled 4x4 + about an inch, no higher, so it is not a monster truck by any means

Had it on my 2WD DRW when in the mountains, took a while to figure it out but it ended up being the brake slide pin not allowing the brakes to retract all so the brakes were not cooling off all the way. When they cooled the warp was gone and every thing was normal again. I also had the same problem after hitting a bump but that was a tire with a broken belt. I would remove the calipers and clean and lube the slide pins.

I agree! This often changes the entire as designed, geometry of the suspension..

If the problem has happened since you did the lift, then you have your answer. The lift would raise the center of gravity of the truck, and in a turn, that could make the truck want to roll to the outside of the turn.

You need more caster! Dodge pickups do this a lot. I dialed in more caster years ago myself. Is this a twin I-beam front end? May take a front end shop and some aftermarket parts to give it more caster. For all of those talking about the lift, it most likely removed caster.

I own a 02 ford f-350 super-duty dually. I bought it used with 18000 miles and during a test drive I hit a small bump and had the front wheel wobble on it. It makes the steering wheel wobble back and forth until you slowed down. It turn out that lot of super duties did this if not equipped with a steering stabilizer which mine did not have.The dealer installed one and the problem went away.I would also check the main drag link,it is the rod that goes from the steering box to the right front side of the steering linkage.The joints can wear and be very loose and cause the wobble.I had this problem on my 73 ford f-150 the were so worn out the would just flop around.

I've worked on this stuff for years,still have a shop...death wobble,go right to the steering stabalizer,then ball joints,your problem will probably be in that area.

Might also look at the track bar. I know from my Jeep days the track bar was a very common cause of death wobble. I was always from the school of thought that said the steering stabilizer didn't actually fix, but merely mask issues such as dw.

Spoken like a true Jeeper. I'm going to assume Solid Front Axle. Check the entire steering system and make sure you're not running an adjustable track bar with a drop pitman arm. Also make sure the drag link and said track bar are parallel. Steering Stabilizers are very overrated.

The lift kit may be causing it, but there are ways to beat DW and keep the lift.

EDIT: Just did my research, it's IFS. Can't help you there. Only dealt with SFA.
