Cross Caster Left 2.8 Right 4.2 Vehicle Pulls Left HELP

Your dealer is not doing you any favors adjusting in compensations. Take the alignment specs below to an independent shop that understands live axle setups and compare your vehicle to the “Nominal” specs in the image below. Notice they are even side to side. They may not be able to get it perfect but the closer you are to those nominal specs the better. Throwing money at adjustable arms at this point is pointless until you know for sure you don’t have damage or issues preventing your rig from being set properly to stock specifications. There is plenty adjustability in the stock suspension (assuming you don’t have a lift or damage) to hit these targets.

So this chart answers the question Nominal target should be 2degrees left / right

Again, if the left is 2° then the right will automatically be 2° give or take a fraction of a degree. The left and right caster are fixed to each other and cannot be adjusted independently of each other. I'm not saying they have to set them the same, I'm saying they are impossible to change independently. So if you see more than a few 10ths of a degree difference between each side after they align it then your front axle is toast.

On independent front suspension cars you can indeed adjust caster separately from each other.
