Some pictures regarding geometry to augment the text from Dennis Lacy.


"Reason #3

The built in steering arm on 1932 - 1934 spindles, when viewed from directly above with the spindle in the straight ahead position, the upper steering arm angles away from the center of the axle and puts the center line of the drag link attaching hole 3/4" forward of the axle center line. This creates a 90 degree angle between the drag link and spindle steering arm. Likewise, the lower ends of 1932 and 1933 - 1934 pitman arms are twisted to also create a 90 degree angle between the pitman arm and drag link. This produces equal steering geometry and effort when turning left or right.

All of the typical bolt-on steering arms needed with later model spindles places the center of the drag link attachment hole directly over the axle center line. This creates unequal steering geometry left vs. right because the starting angles are not the same. In one direction the steering starts over-center while in the other direction the steering starts behind center. Most people would argue that it's not something your likely to notice when steering the vehicle and thousands of hot rods have been done this way over the decades. We figure since Ford thought it was important enough to get the steering geometry correct, so should we."
