alignment question.
 

Hello gentlemen,
I have a question on alignment of my 65 gmc. It has a pull to the right, which makes it handy when going around right hand bends other than that, it's a consistent left hand, elbow out the window cruising position. My question is what's the process of getting that straightened out. It's slightly lowered but the kicker is it has 285/50/20's on it. Your knowledge would be greatly appreciated by me and my left arm.

Thank you for your time guys.

First step is to make sure all the suspension components in the truck front and rear are in good shape. Second is a trip to a good alignment shop.

Make sure the tire is not worn to one side as well. Try a tire rotation to see if it changes anything first.
