Home Alignment - Camber Edition

I don't think so. Positive caster means the top ball joint is behind the bottom ball joint. Adding shims to the back will shift the top ball joint rearward, thereby increase positive caster.

 

I am drawing it on a paper and I can't wrap my mind around how it is going to work. When I do it on paper, adding shims in the rear moves ball joint to the front. I guess it has to be the same situation as with steering boxes. Even in some Hemmings article they said you can't use box from front steer layout in a rear steer,but it turns out that here it doesn't matter and jeep box makes wonders in my rear steer Riv, go figure....

On cars, adding shims to the rear increases caster because the control arm is attached on the inside of the frame. On the Chevy trucks, the arm is attached on the outside of the frame so adding shims to the rear will decrease caster. It's possible that some trucks have the arm on the inside of the frame. but I don't recall ever seeing that.

 

I was going to say that's the only way adding rear shims decreases positive caster.

 

Ha, thanks. That one slipped my mind. Thanks for clarifying that to me, mind can sometimes stuck and you are left with nothing .

Good day to ya all.
Peace,
