Vibration coming throughout the truck, need your oppinion
 

Well first i got a squiking noise coming from the center of the truck from underneath and its in sequence with the drive shift spinning... would that be a u-joint startin to go??

and i also have a slight vibration in the truck, you can mainly feel it through the steering wheel when im on the gass, but once i let off it goes away and it only happens when im doin 30+ mph it gets really bad when im doin 80 haha. rear view mirror starts to rattle and stuff. would that have somethin to do with the possible u-joint problem??

what do you guys think?

Yeah check your u-joints to see if they're loose and as far as the vibration in the steering check the cv shafts and tie rod ends.

U joints in the drive shaft, also you have the crew so it should be the two piece rear drive shaft, could be a bad carrier bearing as well.

X2 what he said!! ^^^^^^^^^^^

always check tie rod end oems are week
