From what I gather it occours when your steering linkage is out of alignment due to a lift kit or bent drag link. This causes a push and pull effect in your linkage when your suspension moves up and down, causing the wheels to turn slightly whenever you hit a bump. A lift causes the drag link to go out of paralell with the tie rod. The only way i know to correct it is to replace the pitman arm with a longer or "dropped" pitman arm. A bent drag like will cause the same problem but its usually less noticable.

simply put? bump steer is when the wheels steer themselves without you turning the steering wheel.

what causes it? the tie rod out of alignment (ie, lots o lift). If the tie rod doesn't travel on the same arc as the front suspension, you'll suffer from bump steer.

Drop pitman arms will work in less extreme cases, but if your angles are really steep, a high steer or crossover steering setup is typically done to minimize bump steer.
