I agree with Mike. Just so we understand, you say you got the ignition & charging systems both working, so that means you started & stopped the engine several times from the key and it all seemed OK, right? Next you started the truck, with it backed into the garage, and when you tried to go forward it locked up the LR wheel after moving only about a foot, right? But then you put it in reverse, and it backed into the garage normally, and stopped when you applied the brake? Earlier I think you mentioned "...greasing the brakes", right? Exactly what do you mean by "greasing" brakes? When you reply if you'll try breaking down your reply into sentences using some periods it will help us understand what you're asking, and also what you're explaining you've done to date. Stick with us and take your time posting, and I bet we can get to the bottom of it.
