mysterious death wobble

[chris989]

Hello all,
1989 v2500, 2 inch lift, 37 falkens

A few months ago i experienced my first ever wobble in this truck. Other than a tire rotation and new steering box nothing has changed. It wasn't horrific but definitely a shock since for more than a decade and many many miles it has never done it.

I've been under the truck all morning and nothing looks a miss.. all tight, no movement in and joint, bushing or bearing. (that i can detect)

If you ever had this and figured out the culprit, please share.

Thank you,
Chris
