so im getting a really bad "death wobble" on my pickup (SAS, hi-steer).

it just started today. noticed a slight shimmy, then after about 20 miles of driving it was getting noticably worse to the point where i dont plan on driving it as is. it will be fine untill i hit a sizeable bump, then it starts and wont stop untill i get it slowed down to about 20 mph. really violent. really bad.

fist thought was steering stabilizer, so i pulled that, and its fine. my steering stablizer is mounted to the pass side frame rail and the draglink. i plan on relocating it to the axle/ tie rod, but it did not do this before in its current position.

havent put a wrench on everything in the front end yet, but it appears tight.

any ideas?
