i checked my shackles they where fine. i just rotated my tires it seemed to help i went for a drive around town, i didnt get a full blown dealth wobble but i can still fell play and im sure in a day or two it will be back to doing it? i just changed out my steering so the alingment is off, but it was doing it before when it was all alingned. i guess i need to cheack the wheel bearing i dont remember if we checked them or not when we did the knuckle rebuild that night/
Matt if the front shackles are loose it will cause death wobble, so will bad tires. make sure your wheel bearings, spacers, and lug nuts are tight too.
How is your Alignment? I have good luck with 1/8" toe in
