when i first drove my truck at wot it made a groan. as well a vibe that was felt in the go pedal and the stearing wheel. it seems to be happening sooner like half throtle or when climbing a grade and gets worse the closer i get to wot ... this is a new thing. never made any other noise on a grade before just a more intense diesel sound and turbo spool. did a search for noises groans viberations nothing seems to match... any ideas??? no miss idle seems fine.

Pop the intake hose off the turbo and check the shaft for play. Also look for exhaust leaks.

AND while looking for an exhaust leak, check to see if the exhaust pipe is hitting the frame anywhere. Mine had a killer drone because of the pipe rubbing the frame next to the tranny.

seems to be with school and work i just cant take the chance that my truck could be out of commision for more than one day if i screw somthing up... but at least i know where it is and have dloaded the howto ... just a time factor

apprentice

shaft is good spins free. tight as far as end play... how do i check for leaks someone said plug tail pipe ?

apprentice

drone is a great word for what is happening. gonna check leaks and contact spots today

You can see them if you have somebody start the truck while you watch. The puff of smoke makes leaks jump right out at you.

Might want to check u-joints for wear,,,, Grease them up real good and see if the issue is still there.

no exhaust is touching any part of frame or leaking, turbo seems fine. it is getting worse.... what next ??? seems to have plenty of power
