What lift modifications have you done. Ninety percent of death wobble problems are from track bars not tightened to the proper torque settings, worn bushings, poor welds on the bracket mounting positions.

Do you have an adjustable trac bar? Do you have a drop bracket for the trac bar? The only time you should need a drop bracket on the pitman arm is if you have a drop bracket on the trac bar. And get the alignment specs from who did it. You shouldn't have needed to have an alignment after putting on the lift. The only thing the shop could adjust is your toe. So, knowing what he set it at is very important. You would have just needed to adjust your steering wheel center. When doing mods you really should try to do one thing at a time so you know where the wobble came from.

I put in my 4" lift. I was about 5" of actual lift. I just re-centered my steering wheel and drove it. No wobble. I have an adjustable trac bar with no drop brackets and the stock steering assembly. I did recently have an alignment done. I installed an alignment cam on the front lower control arm. I also bent my drag link real bad. So, it was needed.

I have a drop Pittman arm but I also added a drop track bar bracket to keep the drag link and the track bar parallel. That keeps you from getting bump steer. It shouldn't have anything to do with Dearh wobble.

An adjustable track bar for the front is recommended. If you look at your Jeep head on, your tire will stick out further on the drivers side than the passenger side. Nothing to do with death wobble either but will help with handling issues. Get either the Teraflex or Full Traction adj track bar. I think Teraflex has some new fangled one that makes it easier to adjust! PM Teraflex or call and ask for Joe, or call David@Northridge 4x4, they will take care of you and offer up a lot of good advice. They are great guys!

A major concern with that lift (and has nothing to do with your death wobble is the rear track bar bracket. That thing has been sheering off the rear factory brackets because of the added leverage. Do a search, you will find some scary incidents where it ripped loose at freeway speeds. Skyjacker makes a support bracket to fix this problem. I can't believe they dont include it in the package.

See as how your lift is new, my guess is that the installer either didn't torque the track bar to 125lbs or that he did it while the Jeep was still on the rack. Loosen both ends of the track bar while it is sitting oin the ground and retighten to 125lbs. If you don't have a torque wrench that equals to "all your might" and then some with a standard ratchet or just "all your might" with a long handled ratchet. I dont think you can over tighten it.

Here is some good reading for you and some pictures you might be interested in.

That's me too! And where I work they are doing major road work, so now I have this problem daily. Such a joy.

so by having to much toe in could that be causing the DW. he did say he adjusted it.


i have adjustable front and rear track bars, i opted not to put the skyjacker bracket on b/c i had the adjustable track bars, im supposed to hear from the tech tonight. all the guy did at the alignment shop was center my steering, i had done it twice on my own and it didn't stay, dunno why, and he adjusted my toe, it was done at sears and he said they are not allowed to touch after market suspension components, so if my axles are not centered he was not allowed to touch my adjustable track bars, hopefully the guy at NTB will have some good news for me today.

I think you did everything possible so far....... Taking for granted "they did the work properly. I have had tires & wheels balanced at one place and had to bring them to a different place to get them done right.

Something has to be unbalanced or it wouldn't do that.... I think.

Maybe double stabilizers too!!!!

Rubimon

Single, double, or triple stabilizers will only mask a problem that needs to be addressed. I know of people that have been running with no stabilizer for some time now.

I would start with the track bar and work from there.

DeepSky

So I've been told, but for me with a tire that can't seem to be balanced perfectly if I ran w/o a steering stabilizer I'd be causing accidents.

Rubimon

Sounds like a problem that needs to be addressed. Go to a different tire shop, have them spin it multiple times, put it on the rear, or press to have it returned to the manufacturer. If you call it a safety hazzard, they will take it back!
