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

Had that happen to me 3 times on my 99wj. Twice within an hour. Hit a small pothole and then a crazy death wobble on the highway. I was very scared and pulled over right away to check the car/tires. Took it to the mechanic. They said the ball joints were bad. Replaced both. The DW never came back. Sold the WJ shortly after.

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

i will post pictures tomorrow. I contacted Kevins Off Road and here is the response they sent me. Is it accurate?

"Drew, it's likely that your drag link (or tie rod) is rotating on it's
axis when you turn left and right. This is typical on a lifted
vehicle. You can remedy most of that rotation by binding the tie rod
ends against each other. You would do that by loosening both tie rod
ends, twisting one forward in it's pivot, locking it down, and then
twisting the other one backwards in it's pivot, and then locking IT
down. This will keep the tie rod from rotating throughout the moment
of a "change in force" of the steering rod."

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

I would do a thorough inspection first to find out if something is bend and if it would not endanger further use of the jeep. Loosing the steering completely due to a part which fails due to being overstressed, is not a good idea. Not telling you that it is dangerous now, but better to check it first, so that you know what is going on.

This seems to be correct yes. By doing what they describe, you prevent the rotating movement of the rod and could prevent some play.

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

Death Wobble is inherent to the solid axle. Occuring at 40 to 45 MPH usually has a root cause in wheel balance. First thing I would do is to swap the front and rear wheels, and see if it still happens. Any looseness in the trackbar will aggravate it. A wheel out of round can cause it. A bad motor mount can cause a reaction like death wobble. I've only had on my XJ, and replacing the ball joints ended it.

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

Here is the pictures of the carnage...I plan on replacing ball joints, tie rod ends, hubs, axle shafts. I figure i might as well get the latter two items done while everything is ripped apart. All parts will be Moog except for the ball joints which are "Alloy USA" and "ToughOne" axle shafts.

I apologize for the pictures being crooked but for some reason my computer does not recognize the changes i made to them

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

I can honestly say thats the first time I have ever seen a stabilizer there.... There is barely enough room for it. It looks as though it may have come in contact with the drag link though.


Have you replaced everything yet?

Yeah there's no need for dual stabilizers on anything especially a Jeep with all the crazy angles under there. They're destined to bind and IMO are just a band aid over an arterial bleed to try to mask the real problem.

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

@Spyder, I followed the directions from Kevins Off Road and they say the stabilizer goes between the tie rod and track bar. When something got bound up, I bent the tie rod. I have not replaced anything yet. I am waiting to get the Ball joints from 4wheelparts.com. I bought Alloy USA. I hope those are good.

@Cheap Jeep, You are right. The secondary stabilizer is a dollar store bandaid. I am an engineer and when I took a closer look at the design of the jeep steering and the placement of the secondary stabilizer...I found something peculiar. The stabilizer is supposed to absorb movement from the DW in the X-axis. It is mounted on the diagonal (yeah i know its supposed to be parallel to the drag link) in the X-Y axis. The dynamic movement it is absorbing from a death wobble is actually in the XYZ axes. Its simply not cut out for the job.

I saw that and I don't buy their claim . If you have some huge lift then their should be enough room. But not in this situation.

Alloy makes good stuff. I had their axle shafts in my Yj and had no problems

Oh make sure you save your receipt. I know they will have a warranty that comes with the ball joints

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

Well I hate to bring this up but since you're in this deep I'd change the control arm bushings upper and lower axle end and take a look at the frame end.The top axle end bushings are a known trouble spot,not expensive and your WJ being an '01 probably needs them or is close to it.
