hello everone, new to the site. i have a 2006 supercrew 4x4 that i bought new and then had a leveling kit and 285/70/17 bfg a/t installed. ever since, the truck has a slight pull to the right. i took it back and he did another front end allignment and said it was dead on. my tires are not wearing and i can't figure this out. i have 2 friends with fx4s and the same leveling kit installed at the same place with the same tires(18" instead of 17") and they don't have this problem. anyone have any thoughts on this.

 

a truck that is "dead on" does not pull to one side....
