Define "Bump Steer"

O.K. I am going to play the buffoon here.

What is this notorious "bump steer" I ferquently hear about.

This is just a matter of expanding the knowledge base and use as a reference.

Bump steer is when compression of the front suspension, such as occurs when hitting a bump, causes the steering wheel to move, hence the name. This is usually caused by the drag link and the track bar (aka panhard rod) not travelling in the same arc, thus one of the links in the system is forced to move laterally (the drag link will move, rotating the pitman arm, backfeeding the steering gear, turning the steering shaft and steering wheel, since the two ends of the track bar are mounted with fewer degrees of freedom.) When the track bar and drag link are parallel and of equal length, they swing smoothly together as the suspension cycles, maintaining parallelism and eliminating bumpsteer.

This is entirely different from Death Wobble, which is much more complicated.

A violent oscillation of the front suspension that can occur when parts are misaligned, worn out, or just improperly designed. Very dangerous at high speeds as it can cause a loss of vehicle control. Hence the name "death wobble".

Nay

thanks, now i know what to call what happened to me on the highway the other day at about 75mph.

Nay,

I set 'em up, you knock 'em down. What a team, eh?
