TJ Death wobbles issue

Hey guys i have done lots of research and i am looking for some clarification before i pull the trigger on any parts.

I have installed an OME 2.5inch lift on my 2006 jeep tj rubicon. Worked fine for 2 months and then started getting death wobbles after a sway bar link broke. Replaced the links with quick disconnects. Problem continued. U joint in passenger side is shot and will be replaced. Steering stabilizer is weak and leaking due to the death wobbles.

I am waiting on replacing the two because a steering stabilizer is just a bandaid and will only mask until it breaks again. The U joint is just a vibration and is not causing the death wobble.

Attached is a picture of my front end. My diagnosis is that the tie rod is not parallel with the ground. I do not know how to go about this. People recommend currie, but it is 750 bucks. People recommend a zj v8 tie rod, but will the beefier tie rod also fix the angle it is sitting at? My mechanic suggests doing a drop pitman arm to fix this. But i suspect it will throw off my drag link and track bar angles and just give me bump steer.

How do i go about fixing this? any help is good help.

Thanks
Andrew

Front angles are fine. Mechanic is an idiot. Replace the stabilizer if it's leaking and make sure the front toe is set in to 1/8". DW didn't cause the stabilizer to leak.

Your tie rod doesn't need to be parallel with the ground. Your issue is that something is worn or wearing out. Do a dry steering test.

I fixed mine with longer shocks and re-balancing the tires. The dual steering stabilizer probably helped too.

For many the zj steering upgrade is fine.
The currie is way stronger, but a similar design and geometry.
Check all the control arm bushings, watch front uppers closely.
Check the ball joints, wheel bearings, and tie rods.
dont do a drop pitman. Its a bad idea.
check the tires, and get them balanced. My death wobble was mostly a tire issue.
something or a few things are getting loose most likely.

At 2.5 inches of lift, stock steering in good condition is fine.

What exactly did you do with/do about the track bar when you installed the lift ? Is the front axle centered under the frame ?

Rebalancing your tires was your fix. Those other two things had little to nothing to do with it.

My death wobble was fixed by replacing the tires. When I bought it in 2011, it still had the original Goodyears. Horrible wobble right at 55mph. I bought it at CarMax, and promptly took it back during the grace period, and they replaced the steering stabilizer, which did nothing. Check the tire balance and see if something is off. If you've got a lot of mud stuck in the trade or inside the wheels, or if the edges of the tires are badly worn, that might be the cause.

So i just got the jeep back tonight after my mechanic throwing in a stabilizer that works and replacing a U joint.

The death wobbles is now worse!! i can barely get up to 80km/h before i hit a small bump in the road and have to come to a slow roll to get rid of the wobbles.

My mechanic wants to straighten out the tie rod and decrease the angle of the drag link and tie rod by putting a 2-4" drop pitman arm onto the jeep.
This seems logical, but after reading everyone saying not to i am very hesitant.

In order to show this to me he disconnected the drag link from the pitman arm. Could it maybe be we didnt tighten it up properly or in the right sequence of parts?

Please help! this is my daily driver!
Andrew

The pitman arm is a solid piece of steel. How is it worn or causing movement?
It has no moving parts. A drop pitman arm will make it worse, by adding bump steer to the existing problem.

Have you, yourself, done a dry steering test?
This is how you will find loose parts to be replaced.
Or just replace everything like I did, lol

You need a new mechanic!

Have you had a tire re balance and rotation? Its a good place to start.
How old are your tires?
What rims and backspacing do u have?

Small amounts of movement in worn parts will cause wobble. Get someone to help you do the dry steering test to figure out where the play or worn parts are. My first experience with DW was worn sway bar links. Now I have a swaying feeling that is going to be corrected with an adjustable track bar, which I assume will be a bad DW if left unattended. You need to find the parts that are worn, and it may be more than one.

That shouldn't cause DW (IMO). You can drive without either sway bar connected and not get DW, just a lot of leaning. Some older model 4 cylinder TJ's didn't even come with a rear sway bar.

Not disagreeing, cause I'm sure you know these wranglers pretty good, but.......

I don't have any more information than I experienced DW a few times before changing the sway bar links and it didn't happen again after. It is however possible that the track bar could have been a contributing factor and just not as noticeable as it is now, but the track bar isn't causing DW for me just a wandering kind of sway.
