bump steer

[jaydub01]

ive got a 5.5 inch lift, drop pitman arm, drop trac. bracket, and bumpsteer is still terrible, i run 15.50 wide tires, and im stepping down to a 13.50, how drastically will this help, or what else can i do to eliminate the problem? ive already replace my drag link about a year ago, and recently replaced my tie rod. This made my steeing alot tighter, got rid of all the play in the wheel, but didnt even touch the bumpsteer, please help the road construction in central florida is out of control

All i can think of is replacing all your bushings, i had the same problem and this helped it

Check the tech articles on W/H and in here on the bump steer. They are really good on providing information to correct it.

Bump steer is when your steering jumps to one side when
you go over a bump. It's a steering geometry thing.

The end of the track-bar and the end of the drag-link both
can move in a circular arc. Unfortunately they don't follow
the same arc. So the (flexible) steering linkage moves around
a little bit because the axle follows the arc described by the
(rigid) track-bar.

You want the track-bar and drag-link to be parallel (or
a shallow X).

Are your drag link and trac rod parallel? That is where I would look first. Are you using a tie rod over steering setup? If so then you probably need to pull the drop pitman arm off to get them back in line with each other.
