Mike Cawein I have the same problem now, Jeep is fine untill about 50 to 55 mph before or after that it is fine but if the wobble catches before i can get through it i have to come to a compleat stop for it to quit and then its fine again. i replaced my stabilizer shock and that didnt realy help but it was shot. I just tightend up the steering box adjustment and that took most of it away but now the steering seems to tight, very sensitive. my tire on the driver side is starting to wear funny with the high and low tread spots, is it possable that this problem could be the steering box? Ive noticed this happens to alot of the 04 wranglers as mine is too.

Shelby427 Agree with Jerry, you have a tire problem.
Ours had what looked like nearly new Wranglers on it when we bought it.
Rotated/balanced the tires as I was seeing a little bit of chopping on the fronts.

Went from no problem to a terrible shimmy at 55. Could drive up to it and through it.

Started looking closer and first off saw the tires were built in 04, and I could see some dry rot between the treads. Jacked the jeep up and spun the tires to find the two now on the front were not round. 1/4" in difference as they spun.

So in trying to fix a problem I ended up creating one.

New BFG Mud Trackers took care of it.

TJWenatchee I had a wobble on my old 77 Dodge power wagon with a 6" lift. Faster I went the worse it got. Had all four wheels balanced. No change. Thats when I learned I needed to clean the INSIDE of the wheels after spending time in the mud. (Why the guys balencing the tires didn't notice I don't know) It was about 2 inches think and like concrete on the wheels. Someone from Montana who was used to the problem tipped me off. My wife and I spent hours chiseling out the caked on mud from the back of the wheels. There was no more shimmy.

markphillips30 I had a death wobble for almost 2 years. I replaced TRE, shocks, obviously balanced and rotated many times, replaced the tires, track bar and front rotors. I took me so long to figure this out that my steering box started to leak and eventually leak to a point i would put an emtpy laundry container with kitty litter in it under it. As it turns out, i replaced my engine mounts and GONE no more death wobble. For me it occured around 60-65 mph. I write this to let you know the one thing i learned is that in a jeep MANY things can cause a death wobble.

Like Blackberry says "Start with the cheapest fix and work your way up. Checking parts is free."

Jerry Bransford A speed-sensitive wobble, oscillation, steering wheel shimmy is 99.999% of the time nothing more than a wheel that isn't spinning true. Usually a tire that isn't perfectly balanced or perhaps a bent wheel which is far more common if you are running steel wheels. But usually it's nothing more than the tires just need a more carefully performed balancing. Many tire jocks only balance tires to what they consider "good enough" which for a TJ, isn't good enough unless it is perfect. And the bigger the tire, the more "perfect" becomes the operative word where tire balance is concerned.

sdyates I have an 06 tj ,the steering shakes left to right a little at 55mph,im about to break down and get new tires too...did it really fix your problem
04-10-2011 10:44 PM
Blackberry I too had a similar problem. First I changed the steering stabilizer ( minor improvement). Next I changed the track bar ( one bushing was worn out, better improvement). Finally, I checked the ball joints. Driver side upper joint was bad. Replaced it. ( fixed it!).

Start with the cheapest fix and work your way up. Checking parts is free.

03 RUBI OK Jerry, I will defer to your superior knowledge and never differentiate between u-joints again.

No, I would only call that replacing the u-joints which is not a difficult process. I have done that job on the trail. You can see part of that job in my website below in the earlier of the two Sledgehammer trail pages.

Just took to mechanic and he tightened some balance bar under front of vehicle. As I approach 55 I feel it wanting to shake, definately better but the shake comes and goes. He told me I may need to get a stabilizer on the steering column. Has anyone else experienced this? Would appreciate any help I can get!

Thank you!
You will probably hear a hundred different ways of how to fix this issue. The best thing to do is start with the simple things first. Then talk to a Jeep mechanic that knows his stuff. A standard mechanic is a Jack of All Cars but a Master Of None.

The Death wobble does definitely suck!

Yes Jerry, I understand that. The point I was getting at was: If the front axle u-joints need replacing aren't they part of the axle and therefore you would refer to it as "replace the axle" as verses "replace the u-joints" (as on the drive shafts)? Curiousity is getting the better of me.

radar I had the same problem with my tj around 55 mph had the stock tires rebalanced had 26,000 miles on them still had the problem but not as bad. Got a new set of bfg's /at and no more shimmy
06-03-2010 09:57 PM
JDetlefsen Mine does the same thing. Stock everything. 55mph its not terrible or barley noticable but it wobbles....havent bothered messing with it yet

Bad U joints causing the steering to shake??? That's a new one. I always figured bad U joints would cause driveline vibration instead. Always learning something new on WF.

Ignore the doofus who told you that. Providing a little toe-in with a RWD vehicle allows the tires to be straight when actually driving. Setting it with no toe-in at rest would cause you to have toe-out while driving.

val thanks, I'm going to try the rebalane and elignment again this weekend. All tires are sstock size. I have replaced tires twice during this hold thing. I've been told to have the tires aligned straight.
06-03-2010 08:41 AM
val I have replaced tires, which are stock. I'm ready to start replacing front end parts. I'm told to have an alignment and have the tire man make them straight.

sevenservices ^^^ x2 on tires... At least, check 'em first before spending to much money. Rotate 'em and see if the wobble changes feel. You can also take it to a good tire shop and ask them if they can check your tires to see if any of them are "chopped". Thats when the tread starts to wear in a cross pattern, everytime the tire comes around to the "chopped" tread area it will shake the vehicle slightly. Its not easy to notice just by looking at the tires but a good tire mechanic should be able to run his hand around your tires and tell you if there are any chopped areas that would cause it to shake.

This is a very, very common problem with tires that often gets overlooked. People spend hundreds on new parts and mods that arn't needed... But, its hard to find a good mechanic that will actually troubleshoot rather than being a certified parts replacer.


and... Welcome!

Check if tires are balanced? Rotated around to see if it makes a difference? what tires are you running? What have you tried?

Mine did it at 65 MPH, would shake like hell. I could blow through it and all would be fine at 75-80 MPH. I never could get it to quit no matter what I changed. I didn't worry about it to much cause how often do I go 65-70 MPH except on the interstate?

Anyway, when I changed tires, problem went away completely. I went from SuperSwampers to something more road friendly and my ride is like night and day. Better gas mileage, more power, great handling. no shaking.


Not suggesting you go out and buy new tires, but you may want to keep it in mind when you need to buy new ones.

One thing that never (!) causes a shimmy is a defective steering stabilizer.

My Jeep "shimmies" because one of my rims is so badly bent that it is unbalancable.

Atthehop I had it bad and found a TSB to replace the steering stablizer with an updated version. It made no difference. I ordered a new track bar and then realized I did not see the grease fitting on the joint so I started to grease it more often and not it is almost gone. I only had 50K on my 04 when it started and now it has 65K. Check and see if you have a worn track bar joint or loose mount at the other end.

I've got this on my Jeep and I've had it on my Toyota p/u before. I believe it's tire related as it has only happened to me on worn tires (both vehicles had/have MT/Rs). I don't know if this is the correct term but a certain "harmonic" occurs at ~50-55 mph with worn tires that causes a shimmy of about 10 or so degrees in the steering wheel. Below 50 mph and above 55 mph no shimmy on either my Jeep or the Toyota that I had.

Bigstonz Google "Yucca Man death wobble"
Rotate/balance wheels
Tighten track bar bolts, esp at frame
Recommend Monroe steering stabilizer
All that helped, bur Currie front lower control arms eliminated my problems
