death wobble occurs only on lifted cars?
 
upon search, i can't get a clear answer as to which minority of owners this happens to.

Does death wobble only occur on lifted setups? i will use my rig as a dd and sifting through some of these posts turned me off a little about making this a future mod as i do alot of highway driving.

Just want to add that i will be running "the combo" if that is a factor in this topic.

thanks

Can happen to an all Stock Jeep as well.

No ... It can happen on any solid axle vehicle with a track bar/pan hard bar. Extra precautions need to be taken to make sure the track bar/mount and bushings are torqued and in good shape.

thanks, appreciate it guys. for my needs and from what i skimmed in that bolt post, which of the 3 would you recommend to "do the the job" (ebay, northridge, synergy)?

All will work from what I saw. How much do you want to spend? I just ordered the Synergy kit, which is overkill from what I read but I am a big fan of overkill.

i will spend whatever for piece of mind, but if the bolts are all the same build quality and just a packaging/name brand difference between ebay and synergy, i don't mind saving a couple bucks on ebay. i read northridge is a step up in strength.

A lift just increases the probability of DW due to the additional stress it imposes on the steering system (bigger tires usually follow the lift) and the possibility of not tightening components as required during the installation.

Grade 8 is all you need. Don't buy into the grade 9 bolts

You know the ones that are hydrolic And bounce up and down.

Death wobble occours for many reasons, but it's suspension movement feeding into the steering causing a cycling affect, steering left to right to left over and over again very quickly. It's caused by too much free play in suspension components. A major cause is slop in the track bar do to wear in the bushings. It can also be caused by bad kingpins or loose tie-rods on the steering link.

The reason why lifted jeeps encounter this situaion more often than stock is do to increased suspension angles. The tracking bars job is to push the axle to the passenger side during spring compression to keep the distance from the steering box to the steering knuckle static, eliminating bump steer. As ride height is increased the angle of the track bar increases. With more angle, the track bar causes the axle to shift from left to right more drastically with compression. This exerts increased force on the bushings in the track bar, causing it do get sloppy faster than with a stock setup.

One fix is replacing the full thread bolts that mount the track bar with shouldered grade 8 bolts. I'd suggest a washer on each end and using a nylock or stover nut to prevent loosening.
