You can eliminate bump steer by changing the angle of the linkage on the steering turnbuckles by adding or removing shims. This happens on real cars as well as RC cars. Here is a picture to explain bump steer.
Exactly...Bump steer is caused by differences in suspension angles. Most likely what was causing your car to handle strangely due to the ball being too tight is that a pivot ball that doesn't move smoothly will cause the king pin to bind so you will either not get full suspension compress, suspension will not fully release, or the suspension will move slower than it should due to the increased friction between the pivot ball and the king pin.
