I know what will fix that...

LOL! Just kiddin, I hope you get your truck fixed real soon. I have heard that in some cases (depending on the type of 4WD and transfer case) the front wheels need to roll a little bit before they take hold. Knida like put it into 4WD before it's needed. I'd doubt that's the case though in a full size pick up. Anyway, good luck and FISH ON!
