I had that happen to me on my '01 back when it was on 35"s. I took a trip out to see my grandma in Nebraska and rotated my tires right before I left. I torqued them down like I always do and everything seemed cool.
Well I get to my grandma's house and she had me run to the store for her, so I start driving and I hear this weird squeak coming from the passenger front. I get out at the store and check everything and it all seemed ok.
Well on my way back home I'm cruising along at about 85 mph and the truck started shakin like a wet dog so I fly off on the shoulder and stop. Every single wheel stud was sheared off and I had only one holding the wheel on. If it hadn't of been for that one wheel stud, I would have flown off the road into a solid wall of trees. Needless to say I kept that wheel stud and its now framed for saving my life!:hehe:
