death wobble

I was driving my 2000 psd yesterday and hit a bump and had a TERRIBLE wobble in the steering wheel til I slowed down then went away til I hit the next big bump. The only thing Ive changed lately was the drivers side tie rod end and calipers. I set it at 1/4" toe in and it drove fine for a few days. Sat for 4 days and went to drive it and now this happens.

After searching it looks like tire pressure is the #1 cause. I read you should have 60psi but my tires call for 50 max. Im running 40 right now. What should I set them at?

I don't see tire pressure being the cause bud. Do you have any suspension mods?

Its not the tire pressure I run my fronts at 29 psi and rears at 25 and its not a issue.
How is the front end, is there any play in the steering wheel. A loose steering box can lead to it so can a bad alignment. Loose ball joints etc, anything loose can set it off.
Some negative caster helps control it as well. I was dealing with it on my truck and adjusted in some more negative caster and it cleared mine up but different things can cause it.
How is your stabilizer shock? This of coarse masks it but a bad stabilizer will open you up to it much easier.
Check the steering wheel play, start at the steering box if there is play.
Good Luck with it.

Sorry I thought it was in my sig. I have a 6" lift and 37" tires. Ive had it on there for years and all was fine. I dont have a stabilizer but never needed one either. Theres not much play in my steering. How would I check the steering box? Could it be an alignment?

Something is loose/worn somewhere. You need to get under your truck and check every component to do with steering and the front axle. Check bushings really good. Get someone in the truck to turn the steering wheel back and fourth and watch for play

It did happen after I replaced the tie rod end but I set it at 1/4" so it should be fine.

I'm going to guess its a alignment issue, you said 1/4 toe in ?
May be too much, I agree with above post I too experienced it also myself when it was misaligned.
