My right front tire is wearing on the outside edge but the truck does not pull to either direction. Do I need herbs washers and a cam bolt kit to fix the alignment? What are the part#'s for cam-bolts? where do I get the washers? and finally what are the Lightning specific alignment specs? sorry for my ignorance! Any help will be greatly apprechiated!

If it is just the outside edge, then there is probably too much positive camber. I think you should be able to fix it with a good alignment.

Alignment shops should be able to get cam bolts, or you can get them from NAPA.

Go here for alignment specs and information.
