MCummings- When I look at the frontend, the track bar is longer than the drag link, and at a slightly different angle than the drag link. Simple geometry tells you that if you have the two bars at the same length and angle, as your suspension compresses, your wheels will track perfectly straight, and this will eliminate bump steer and death wobble. I am going to do a thourough(sp) examination tomarrow, and we'll see what moves.
I know is it scared the **** out of me right when it happened. The 2nd time wasn't as bad. Anybody know where to get just the shock part of the SkyJacker steering stabilizers? I will just make my own brackets.

Tires turn left,, axle move that direction, and when teh axle moves, the wheels will turn. So the tires are turning left and right quickly because the axle is moving left right,, the force of each other part aggravetes itself.
Make sense? or am I off the wall and out in left field?

The best recommendation is to get the Lukes Link AND the urithane bushing for the other end of the trac bar. I doubt the steering stabilizer will help out at all in this situation.

Hey, No Problem. I just wish I could be a bit more clear about it.
Maybe this is what it looks like?

If you could imagine it, the pictures are of the front axle and tires.
Start from teh bottom and work your way up as if looking at "Frames" of a movie picture.
The first picture represents normal cruise, the * represents just the right bump.
When you hit the bump, it's not for the fact that the axle goes up, and causes a bump steer condition, but the fact that only one tire hit a bump, and since you have a loose or worn front end component (usually trac bar) the wheels turn that direction,, in the case pictured, left, then the tires try to turn back very quickly, but because the axle was able to move, the tires turn back much faster than inteneded, and over-countersteer.
As you can see in the picture, usually DW will start with just a slight left/right motion of the wheels, and quickly progress into forcing the axle to move left/right also.
Hopefully I'm a little bit clearer...

EDIT: The periods next to my "presentation" are for proper spacing of the frames, since UBB code ignores my spacing when typing up a message.

i agree you probably have some worn suspension parts but i have experenced this on a brand new truck missing steering stabilizer because it was bent by a rock and was waiting for part. id inspect all suspension and steering componets for wear and replace them and buy new steering stabilizer. my 2 cents
