Just a clarification of caster settings above 5 degrees is only possible with the F53 axle. Shims are installed between the axle and spring allowing greater adjustments for caster. The cutaway chassis (E450, E350) use bushing in the ball joint which can only go to a little over 5 degrees caster. The aftermarket 2 piece bushing can only adjust to 2.5 degrees caster.

In the beginning I created 2 threads, one for the F53 (Class A Forum) and one for the E350/E450 (Class C Forum).

The moderators must have assumed both to be the same and scratched the E350/E450 in the Class C forum. Then the F53 was mysteriously moved from the Class A Forum to the Class C Forum.
