Just bought my first Jeep (2000 Wrangler) and I'm trying to fix the intermittent death wobble that occurs. I got an alignment done which helped a bit. I was planning to add a stabilizer bar on the front but the mechanic came back with adding sway bars instead. However I have an articulating suspension with a 4" lift. I have to remove pins to trigger the articulation. Won't changing sway bars basically render this useless? I also did some research and found many times it's a track bar that causes wobble. Any advice on which solution to try first?

Sway bar has nothing to do with DW. Like mentioned focus on the track bar, worn holes or a cracked weld joint. Also have somebody steer the jeep 9 to 3 while you inspect all front end components. Looks pretty rusty and old under there. Check everything Tb's control arms, tie rod ends, steering box, tire balance. Lastly the stabilizer which might actually band aid the problem.

How are your control arm bushings?

I guess he covered that ^. Dry steer test didn't turn up anything for me I'm still hunting down my wobble that kicks in around 50mph, though I'm honestly not spending any time on it just yet.

Does it taper off ? Most likely the tires.

I changed my stabilzer shock with a skyjacker and the death wobble was totally eliminated.

Like covering a skin cancer with a band-aid, installing a new steering stabilizer didn't cure the real root cause of your death wobble, it only masked the symptom.

I'll write more about death wobble later tonight after I get home from work.

It does taper off and I figured the same thing. I had them balanced, and before the shop took my cash they said they wouldn't be able to dynamic balance them and that they could only do so much. They are E load MTR/K's in a 265-75-16 that the PO put on. I will be changing them out in March.

The wobble for me is generally instigated by a bump in the suspension cycle. From there it builds from a shimmy into a wobble, that is obviously compounded by the tire balancing factor at the usual speed for those issues: 40-50 mph. Above or below I can still feel the shimmy over bumps but it's less dramatic because it doesn't build on itself.

Suggestion...may or may not help...If you can figure out which 2 tires are the "most balanced" watch them actually balance and than take the 2 tires that require the least amount of weight to "balance" and put those 2 on the front....and also may do the tire pressure/ chalk test...for me with mine I am only running about 26-28psi in my tires....had DW about 4 years ago and it was in the tires at that time...but that isn't always the case....but if gonna be replacing tires may not be worth the effort to "fix" at this time....IMO the "pucker factor" for me after hitting a set of RR tracks or whatever would set it off, (usually RR tracks) I was working checking everything for 3 days till we finally had tires "re-balanced and rotated" to the least weight on the steering tires...and it went away...yrmv...Good Luck!!!

Appreciate the advice, however the PO left the fronts on waaaay to long and they are cupped pretty badly. I moved them to the back so they aren't affecting the front but that means I'm stuck with the tires where they are for now.

I'm getting the MC track bar soon, new wheels and tires in March, and I'll be swapping to a ZJ tie rod setup around then too. I'm going to shake the front end down again this weekend and see what I can find.

Going to say to have them road forced. Def swap those out for a C rated tire.

Thanks everyone for the feedback. I took a closer look and the bearings on the sway bars were shot so I replaced them. I also replaced the shocks as I discovered they were junk too. I'm not getting any wobble so far testing up to 50 mph. I'll continue to monitor thru the week.

The ride is much more rigid now. Tighter steering in general after tightening the steering bolts and fixing sway/shocks. No wobble but not much give, this may be normal and I need to get used to it after the repair. I'm sure the ride given the lift kit and wheel specs isn't supposed to ride like a Cadillac.

FWIW IMO don't sell a good lift shocks and tires short my '04 TJ rides better than it did new after I put different springs, shocks, and tires on it....

Huh, maybe I should get a 2nd opinion on the ride then? I'd love it to be a little smoother. Thanks for the input.

With the right choice of suspension lift, springs, and shocks, there's no reason a lifted Jeep can't ride as well, if not better, than an unlifted Jeep does. Mine certainly does. Even my picky wife thinks my Jeep in its current configuration rides well, unlike what she thought of my first Jeep's first suspension lift.

what is a good choice when choosing suspension lift, springs, and shocks?

That depends on what your budget is. Severely limited? Unlimited? Closer to one of those than the other?
