Caster how to add some

[Alan]

What you have to remember is that it should all line up. That is if you have to force the radius arms into position then something is wrong. You should certainly have more than 2 degree of castor, but it’s affected by many things. I’d look first at bent front crossmembers and radius arms. The front forging (not a casting) isn’t usually the culprit in my experience.
