Bump steer is created by the tie rod end not traveling in the same arc as
the outboard ends of the a-arms. There are ways to adjust bump steer. The
most common way is to heat and bent the steering lever. Caution here to let
the lever coll naturally after heating. Quenching the lever after heating
will increase the probability of fractures.
In some applications bump steer can be adjusted by adding washers to the
union between the tie rod end and the steering lever. This raises the
height of the tie rod end.
In most cases factory bump steer is not significant enough to create normal
driving difficulties. Adjustment of bump steer to zero is for competition
cars on paved tracks.
