jeep vibrates..

I have an 03 Rubicon, i just had my tires rotated i have 35's when i get going around 50-55 i don't get the death wobble, but the jeep vibrates steering wheel everything, it never did it before i had my tires rotated, do i need them balanced again or front end alignment or do they need to wear a little bit, they said they balance them everytime they rotate them, what do you think..

Guaranteed that is nothing more than a tire or two (or three) that is out of balance. 35" tires are hard to balance and not all shops will take the time to balance them to 0-0 (perfect) as a Jeep requires.

Call around to your various tire shops until you find one that has a "Road Force" tire balancing machine. Take your tires there to have them balanced and make sure they use the Road Force machine. My local Discount Tire store has a Road Force machine but because it takes longer and more expertise to use, they hate to use it unless the customer insists on it. I always insist because I have learned their other (standard) tire balancing machine doesn't get my 35" tires balanced well enough.

They hate to use their Road Force machine so much due to the extra time it takes that I have to stand there and watch to make sure they use it.

Just so you know, a new steering stabilizer is never (!!!) the cure for Death Wobble. A new steering stabilzer can suppress the symptoms enough to make you think it is cured but all it's doing is suppressing the symptoms. The underlying actual cause of your Death Wobble is still there, held down by the steering stabilzer, just waiting to come back to bite you when the new stabilzer gets tired of being overworked like that.

It's like you jumped on a gorilla who was going after you and you was able to hold it down for a while. Eventually, you're gonna get tired & that gorilla is going to jump up and go after you again.

There is no "specific cure" because the cause is often different.

Start with looking under it while someone wiggles the steering wheel back and forth. Look for something loose, tie rod ends, track bar ends, drag link ends, broken mounts etc..
Try tightening all the bolts and nuts.
Look for mud built up on the wheel insides. Remove if needed.
Look for a cracked frame.
Jack up each wheel in turn and spin it - look for a bent rim or a "lumpy" tire.

Get the tires balanced with a Road Force balancer machine - it's a different way of balancing - and its very effective!

If it's still present, try removing the bolt on the passenger side end of the trackbar. Pull the trackbar down out of the way. Try the bolt back in the hole - see if the hole has become elongated or warbled out. The bolt should fit snugly in the hole. Gorilla tightening that bolt may help for a few miles, but it won't last. The hole has to be repaired back to snug.

A new steering damper, or even adding a second one will not cure it. It may temporarily help a little, but it cannot compensate for something loose or broken.

Let us know what you find.

If all else fails, check the torque on your lugs. Star pattern, 100ftlbs. Personally, I'd do this first since it's fast, free and easy, but..............

You almost sounds like the same issue I'm having with front shake, that makes steering wheel and dash shake.

After doing the tire check... next look at your Drive Shaft u-joints, I found some bad ones on mine and will be changing in the next day or two.

Since DW is often a result of one or more problems that singly or in combination cause DW, there is no single universal cure.

DW can be a result of an issue with any of the following, or a combination of them. Out of balance tire(s), a loose passenger-side track bar mount, loose ball joints, loose shocks, bad (loose) control arm bushings, etc. Bad tire balance is a common cause, especially when the track bar's passenger side mount has any movement at all from a loose bolt to a worn/wallowed out track bar mounting bolt hole.

That is what it is like a shake in the steering wheel and the dash vibrates or shakes..

Does it only do it under acceleration.... and when you coast it's fine.

Make sure tires are balanced and no major wear patterns or wierd wear patterns.

Check the rear DS first, jack up the rear end to take the weight off the DS and then grab the u-joints at the rear pinion and then check them at T-case out-put.

If those are OK, then move to front DS and then same thing check u-joints or you can also remove the front DS and take for a drive to see if still there.

What is the difference between what the OP has and DW?

Because my truck is doing the same exact thing as his. At 50-55 it starts shaking until I get below 50 again. My tires are completely bald though and have not been rotated or balanced [let alone an alignment] in God knows how long (bought the Jeep 3months ago and that's how it was).

Is this considered DW or is it just a tire issue?

Not trying to thread jack Poliux, i just figured since our problems are exactly the same that I can try putting this here instead of opening up a new thread.

Sounds like you have alot of maintenaince you need to do.

DW would be where the front end starts wobbling back & forth where the steering wheel pretty much rips out of your hands back & forth until your able to slow down.

Search youtube for DW and will give you a good idea of what it looks and feels like.

Is that what you are describing as Death Wobble? If so, that is not Death Wobble... not even close.

DW is an EXTREMELY (!!!) VIOLENT shaking of the front end that is bad enough that you have to immediately slow down, pull over & come to a near stop to regain control of the Jeep. It's bad enough that other drivers will notice it and get out of your way.

Yea, then I'm assuming I don't have it. Mine gets to a point where I feel as if I should slow down, but if absolutely necessary, I can keep on going.

Mine has the same symptoms as described here by Nova and Pollux. My vibration happens between 55-60... but only sometimes. If I slow down, it goes away... if I speed up, it goes away. If I stay at that speed range, it gets progressively worse... so I do not stay there much. Mine will do it consistently for a few days... then go away for a few days... really frustrating.

However, I am getting new tires this weekend finally. With the accompanying balancing and alignment... which is probably what it needs anyway.

knock on wood... but the new tires, balancing & alignment seems to have stopped my vibration issues. I put on 31x10.5 BFG AT's. I was actually quite surprised how much the ride quality improved over the stock tire. Those Goodyear wranglers are crap.
