Do A's turn sharper in one direction?

[nosoup4u]

If not, someone explain this to me. With the wheels pointing straight ahead, and the drag link disconnected, the steering arm (the one with the ball on the front axle), travels much farther forward from a given point than it does backward.
I can't seem to figure out the geometry of this thing.

Steering stops equal?

[Jim Brierley]

The steering arm should be directly above and parallel to the axle. If not, the arm is bent and will steer as yours is. Heat and straighten and it will be fine.

Which arm is the "steering" arm? The Spindle arm?

Maybe it has to do with the Ackermann angles?

PLEASE listen to Jim. This is most likely your problem. It happens QUITE OFTEN.

Ackerman is a term that is not immediately descriptive. Another term for the same general thing is Toe out on Turns. Certainly things can bend in a variety of directions. First, the steering arm is the arm bolted to the LH spindle on the inner side for L.H. drive cars. This has 2 balls on it, one for the tie or track rod that crosses over to the other wheel assembly. The remaining ball is for the Drag link and on to the Pitman arm and then to the steering sector in the s. box. The best way to show a bend that will create problems is to look at the distance between the tie rod ball and the rolled edge of the backing plate. Important that both R.& L. are the same - Roughly 7/8 - 1"". This is done with the tie rod removed and the balls exposed. Second thing to verify would be to look at the distance from floor to ball. Compare R.&L.But elevation will have little effect on Toe out on Turns. Rear axle thrust angle will cause un-equal center position on the steering wheel as well as steering stop discrepancies. Excellent diagrams on WICKI as indicated by 1955cj5 on post 4.
