Do you have adjustable control arms?
Yes, front lower. Although it is possible, its doubtful. Had a very reputable SoCal off-road place do the alignment and validate everything after the installs.

Only an issue on '12s & up , iirc

True for '12+. Mine is '08 and there is either at least one Teflon part inside the box itself, or PSC uses Teflon in their pumps (they say they do not). My Teflon bits were more like small chunks, too thick to have come from a hose liner.

Many people set the toe out 1.5-2. I get a much better ride and stability with it in 1-2.

If it's not toe, I would be willing to guess the control arms are set to the wrong length, causing the axis of the ball joints to be off. That screws your caster, and scrub radius. If they are not set to the proper length, ensuring the wheel track is straight, the thrust angle will be off. That will also cause the issue, too.

You should adjust both upper and lower control arms to correct the center placement of the wheel in the opening, but also to ensure the caster is correct. If they lengthened the bottom and didn't do anything to correct the top, that's a problem.


Of course, this is assuming all of the parts you replaced are in good condition. Drag link and tie rod ends are notorious for causing death wobble and lots of other steering problems.

This doesn't apply to your issue, but for guys running Dana 60's, they get bad death wobble if the preload on the kingpins are to light. That info may help others.

There are a ton of Teflon seals inside the box

Thanks for the confirmation. Couldn't really tell for sure even with all the rebuild threads out there, and I hadn't taken mine apart.

FWIW, here's what I found:
