Steering and suspension geometry setting details

Just FYI, you cannot change one side without the other following. Meaning what ever the caster is on the right then the left will always be the same. You can cause some bushing bind at best and maybe cause the axle to be a bit out of line with the chassis but that is marginal if much at all. But so long as you adjust both sides at the same time and the cam or eccentric bolts are in the same general orientation then your fine. But again you cannot have one side of the truck with say 1.5° of caster and the other with 3°. That's impossible unless you broke your axle in a wreck. Any delta between left and right is either alignment machine error or tolerance maximums from Carraro.

Agreed, tolerance changes would be minimal and as I mentioned “slight”. The only risk you’d run, as you mentioned, would be the potential of one cam adjusted a little ahead or behind the other taking the axle slightly out of line but it would be within the gross tolerance specifications. Assuming you loosen both caster cams at the same time adjusting them will make the entire axle rotate to the new caster angle if you keep them both in the same orientation.

Either way, I’d still make the changes on an alignment rack to ensure axle remains straight with chassis and to watch and record your final caster settings and verify all other angles. After all, you are there making changes anyway so check everything so you know what you have and then drive and see if you like the caster changes you made.

anyone got a video showing how to adjust hte bolt for us rookies is it just as simple as tightening it down to max or more precise which means bring to a trusted tire shop

yeah but really doesn't show you much expect which one's to adjust... usually they show you how to exactly do it, but probably liability on this one

It will become brutally apparent once you get in there.
