I lifted my truck almost 6 months ago and have had death wobble since I got my 31s it was very slight at around 50 MPH I seem to have no play in any of my steering components... I put my stock wheels and tires on to see if that was the problem and it got much worse... Does this make any sense?

 

I've had some Death Wobble.

Have someone turn the steering wheel while you are sitting under the front end. Watch every joint. Look for anything that is moving incorrectly. The tighten it up.

I did this Sunday after having wobble on Saturday. Drove 225 miles at freeway speed with no problems.

Are your wheels all balanced? Have you had an alignment recently?
If no to either, do that and our problem might be gone.

 

^+2 on the balance & alignment. The only time I've experienced death wobble it was due to the tires being out of balance. The front end was tight and it baffled me at first. Fortunately it was the easiest and least expensive thing to correct.
