front suspension 2x4

[rterril02]

I recently bought a 1986 f250 with the 6.9. My uncle, who I bought it from, told me it has bad "bump steering". I was wondering what the set-up should look like. So far all I can tell is it only has tie rods. I was thinking that maybe its bad because there was no track bar, steering stabilizer, or sway bar. I don't know what was stock but I don't like dealing with bump steer. I've done some research on the issue but I am a rookie. I have the twin beams up front not the single beam. Thanks

Some have sway bars. I would check the bushings where the ttb mounts to the cross member under the motor. Have someone turn the wheel back and forth to look for worn parts. Also jack it up to check the king pins

You can add a steering stabilizer, put one on mine. It does help.
How many miles on it?

A steering stabilizer will "help."
But it's just a bandaid to bigger problems.

The radius of the TTB is not the same as the radius of the relay rod. Ok, in a tight system that won't matter so much but any slop in your tie rods, joints, and the TTB pivot etc will complicate the issue.

Here is a more detailed explanation.

I took my sway bar off over the summer when I did my front end mods. I haven't noticed a difference in handling. I think the suspension is stiff enough that it really doesn't matter. I would check all your bushings and get an alignment.

Ford did not sell their trucks with an unacceptable amount of bumpsteer from the factory. If it's totally stock, look for something bad or worn out like the other guys suggested. Don't worry about the theory of bumpsteer unless your suspension is not stock.
