Aligment help needed

[JB904]

Let me start out with what has been done and what its on. I have a 2008 crew cab short wheel base diesel 4x4 with a 2.5" readylift leveling kit and 37" Toyos on factory 20" wheels. Everything has just been installed and aligment has been done twice still pulls to the right they even rotated the front tires to cross that off. Below are the specs from shop.

This may sound like splitting hairs, but it's an important difference: Is it actually "pulling" or is it "drifting" to the right? My truck drifts to the right most of the time. From what I've heard it's a Toyo MT thing....they follow the pitch in the road, which tends to be to the right for those of us in the US.

I had a new set of pro comp 35x12.50 on there for about a week before the toyos and still had the pull. Its a pull if I'm changing to the left lane and while changing lanes let go of the wheel it will go back to the right lane.

you need to add .5-1 deg more to the right side to help with road crowning. and it all depends on how bad the crowning is in your area to. but for me a 1 deg difference works

so the castor is 3.0 both sides now the pass side needs to be 3.5 to 4.0 or 2.0 to 2.5?

ya you want it to be 3.5-4.0 on the pass side if you have 3.0 on the driver side. i would say closer to 4.0 would be better. i run 3.5 ds and 4.5 ps on my truck.
