ok, i'm just a little confused because i thought you said the angle of the tie rod changed. whether its up on the high steer arms or down on the stock knuckles, its angle relative to the axle should be the same. Its stroke may change and the ackerman's angle may change depending on the high steer arms, but its overall angle relative to the axle should be the same.

Regardless, the tie rod, assuming its ends are tight and free of play, should have nothing to do with death wobble.
