YJ death wobble

FFDave · Apr 12, 2016

Currently running 35" tires on leaf spring front end with Dana 60 in the front. Death wobble has gotten much more frequent after switching from 10 bolt axle. Do not currently have a track bar on the front. Will adding one help?

I would look at tie rod ends and ball joints or king pin bushings. As to your question... :dunno:

Steering stabilizer will help a lot as well

And make sure your alignment is dead on.

Shackles need to be tight enough too. A track bar will help. What steering setup do you have?

FFDave · Apr 12, 2016

Currently have the stock steering set up. Saving up for ram assist since it still gets driven on the street a lot.

What 60 is in the front? If it's a used King pin axle make sure the bushings are not worn.

Also what is your pinion and caster angle? You should have some positive caster ....Dodge 60 was 2-4 degrees and GM 60 went up to 8 degrees I believe.

4-5 degrees and greater with larger tires. More tire, more caster.

Also and obviously, check the tie rod ends. Also check for roll in the tie rod.

What I've done recently to get rid of DW on two TJ's was to put two grade 8 5/8" washers under each TRE boot at each knuckle. It reduces the misalignment so that it can't generate enough inertia to slam the cross link back and forth. You don't need all that misalignment, the knuckle arm moves very little up/down when you turn.

Or you can get these:

It's gotta be related to caster...the other parts will just make it worse.

Check all steering components and kingpins/balljoints for wear, if ok and you run shackles in the front like stock set up, a track bar will solve the DW.
My 2 cents.
