OK so this morning i head down to get breakfast and about a mile into the drive i hear a loud pop, and then a clunking noise from under the truck. the fwd still works fine. so when i get home i put the truck up on jack stands and check the drive shaft it all seems good except the transfer case is making a loud clunk now. all the u-joints seem good. and i don't think its the rear-end that seemed tight. my carrier joint also seemed loose i could wiggle it around pretty good. i think that the problem is in the transfer case, the rear output shaft has some up and down play in it, and the noise it makes when you turn it with your hand doesn't sound good. any help would be great thanks.
