Hey guys,
long time, no type. i hate to just jump on here when i need help, its like praying to god when you really F somethin up. anyways, i need some help. ive got a wicked vibration in what i believe is the driveline. It only happens between 35-55 through acceleration, and its a pretty noticeable sound, and feeling. like i said, its only during acceleration, and when i let off the gas it cruises quietly. I got under the truck and there is maybe half an inch of play in the driveshaft if i just grab it and try to turn it by hand. U joints maybe?? any thoughts?? thanks a ton..

Sounds like it may be. When was the last time you greased them? Have you hit the diveshaft on anything lately?

02-20-2009, 02:05 PM
probably never, and i havent been wheelin for a while, so i dont think i hit it on anything.

Yep - noise when on the throttle is most likely a u-joint ... it's probably the one at the rear diff.

Hey Hank, we are hoping to all come down to On the Boarder a week from tonight and have a meet and greet. Will you be there? Also If you have time this sunday you could swing by the how north.

This is what mine did when the U joint went out near the carrier bearing.
