[SOLVED] Getting Mini Deathwobble at speed

[JohnnyBronco]

You missed the part where "at speed" was only 60. These will go 104-107 before limiter kicks in

Multitude of possibilities. Tires out of balance. Suspension components need re-torqueing. Factory shocks not up to the task of a much heavier wheel/tire combo.

Not sure what the first part of the post references, but I've used balancing beads for tire/wheel combos that could not be balanced any other way due to compatibility with the equipment. Worked fine.

For a normal DD, I'd still rather get a traditional balance with weights. Otherwise you live with the low speed unbalanced vibration you get with balancing beads every time you take off.

Since I first found out about balancing beads, and tried them, it's what I use all the time. I'm used to catching a lot of flack about them so the first part was about me acknowledging my unpopular opinion

Relatively small vehicle running 37" tires. No surprise that you are feeling any kind of vibration. Most likely out of round and or out of balance tire and wheel assemblies. You may never eliminate the problem.

nope is 18

Issues like this is exactly why I opted for Sasquatch instead of diy lifting...too many variables and potential warranty problems. If a stock vehicle does this just dump in dealers lap and say "fix it".

Granted the OPs lift is ill-advised.

the title of this thread should be changed. That is not a “death” wobble.

Yep! Tie rods breaking, steering systems literally falling apart, and now this.

As it happens consistantly at those speeds, I'd also second an out of balance tire, or something out of whack in the geometry after the lift.

Just as an aside: 'death wobble' is not a consistant vibration. It occurs in a SFA when one wheel hits a bump at high speed and loose (or miss aligned) components - usually starting with the track bar - start a resonance in the suspension. The axle moves too far to one side, the suspension pushes it back too far the other way - rinse and repeate. You have to slow almost to a stop to get rid of it.

Experienced it once in my usually solid JL driving home after a long weekend of wheeling, and found both track bar bolts -among others- had untourqued almost 1/2 a turn. Tightened everything back to spec and it never repeated.

Upgrading tie rods is one thing, adding spacers and 37's is a whole different ballgame. The more you jack any vehicle higher in the air, the more issues you're going to potentially face.

Yeah, that is a shimmy in the steering wheel.

Low speed death wobble is preferable to high speed death wobble. But even the dreaded Jeep wobble is or was not all that dangerous, just annoying.

Having had the dreaded death wobble in my old JKU, I would definitely disagree. It is most definitely dangerous.

For those not familiar with true death wobble:

Possibly a bad tire... I'm having a factory Territory replaced because it fails on a road force balancer. Make an oscillating sound. VERY little feel in the steering wheel but it's there at certain speeds.

 

[SasBLSven]

Check your when spacers and makes sure they aren't cracking. I remember seeing a video by Bronc Buster on that

 

[PowderHound]

I put new wheels and tires (ordered from discount tire direct) on my last Ram truck and had this same issue.. steering wheel would really start to vibrate right around 60mph. Took it to tire shop, they added some weights to balance and it was fixed .
