NEED HELP...Death Wobble...Replaced almost everything and still occurs

I have a recurring death wobble on a 2001 GC with a 2" coil spring spacer lift. I have searched almost every death wobble cure and I am at a loss. I have replaced a lot of my steering/suspension and I still get a death wobble. I do not know where to turn.

So far I replaced:
All 4 shocks (Skyjacker Nitro +2")
Moog Front coil Springs (plus 2" spacers)
Omix-Ada Track bar
Moog Steering Stabilizer
16x8 Pro Comp rims with 4.25" backspacing
Cooper Discoverer AT3 tires (225/75-16)
Wheel alignment from a trusted mechanic

What else can I replace or adjust to cure the issue?

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

death wobble is usually caused by a bad front end part , Tie rod, ball joints , sway bar links,etc.
does it happen at a certain speed? and can you drive thru it ? maybe you busted a belt on a tire. Have you rotated the tires?

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

As Spyder said try rotating your tires. One bad balance job could be enough to set it off. Lifted WJs are super touchy. Then I would start with the tie rod and drag link ends. Also make sure the track bar mounting bracket holes are not egged out and the bolts are super tight.

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

I have brand new tires, balanced at the same time. The DW happened yesterday twice around 40-45mph. The first time I slowed down to get rid of it, the 2nd time I accelerated out of it. I will start checking out the TREs. How do i check them?

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

check all rubber caps on the tie rods and ball joints to see if they are ripped , if so This could be a good place to start

you need to Jack up one side and push on either side of the tire and see if there is excessive play , also from top to bottom.



To check the ball joints - use a board and place it under the tire and see if you can lift up (gently ) on the wheel . If you have a lot of movement up and down then your ball joints are bad. This will also check the wheel bearings as well.

Just because the tires are new doesnt mean they are balanced correctly ( or maybe you threw a weight , one fell off) .

I had a set that were balanced and on the wheels when they were delivered brand new . It ended up they were Counter balanced and did the same thing as you are describing.

Counter balance is when the weights of the wheels are placed so they make the wheel even more unbalanced

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

Today I checked the TREs and Ball joints for play. Everything is surprisingly tight! The track bar is pretty solid, no play. Am i looking for "egged" holes in the upper or lower mounts? I guess I will have Firestone check the balance on the tires since I have a Lifetime Alignment/Balance package from them.

I drive 50 miles a day, mostly highway miles, and I do not feel any vibration or anything. If something were faulty, wouldn't i feel something. I did notice that I can jiggle my steering wheel a little and the jeep still drives straight. Conversely, when driving straight, i feel like i have to "correct" the steering often,

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

Steering stabilzer? Alignment? What about road conditions? Occur during bump or pavement transition? Sounds like you have been pretty thorough with the front end checks. Good luck.

Eventhough i have never experienced the DW myself, my jeep also has some play in the steering wheel. I have to change my tierods, but it seems that there is some play in the steering gearbox as well.
What you also can check is the input rod to the steering gearbox. There is a kind of a coupling which could create some play.

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

I agree with AMSOIL dealer , what are the conditions on which it occurs ? is it after a bump?

Did you happen to check the Joint at the steering box?

To check this , have some one turn the wheel while you watch the joint and see if there is any up and down movement in the joint.

It seems that most older jeeps have sloppy power steering boxes , so it wouldnt be a surprise if yours did as well but, you shouldnt be fighting it.

oh ,and a good way of checking the track bar is to , turn the wheel when the jeep is on the ground and if the whole body in the front ( other then the tires ) move . then you have a track bar issue . It will be a side to side motion

Re: NEED HELP...Death Wobble...Replaced almost everything and still occurs

The two times the DW occurred was on a flat road hitting either a bump or shallow pot hole. So I used to have a Kevins Off Road Secondary Steering Stabilizer on my jeep to help combat the DW. It seemed to work. When I had my trackbar replaced, my mechanic removed the stabilizer because he said it was binding up. (he showed me the bent screws and everything). Well today I reinstalled the steering stabilizer with shorter screws...well it bound up again and got itself stuck or jammed with the wheels cut to the left. As i tried to free it, i must have turned the wheel too hard as not my steering wheel is not centered anymore and there is even more play in the steering. It felt extremely loost on my 25 mile journey back home. I am so frustrated now, I may replace the tie rod and drag link just to eliminate another possible cause of DW.

what pins bent? Can you post a pic?
Also. If you were driving on it and it was bound up . Then you probably bent either the tie rod coming down from the steering box .
Can you also post a pic of the front of the jeep ( drag link , tie rods , etc. ?
You should probably at this point replace them anyway due to the stresses placed on the joints from driving with it bound up.
