Bump Steer

You'll have to plot the toe curve as the suspension moves through jounce and rebound. In order to change it you have to move the pitman and idler arm heights so that it's equal as it travels from the static height.

Sound like fun? It's a real pain.

The easy fix is to align it with as much positive caster as you can get (adjustable tubular upper control arms really help here) with the front end raised about 1" from static and then limit the front end travel.
