    OK Boys, I got a 04 2500hd GMC and last night it started to make some weird noises on me! Going forward its fine, when you shift into reverse and go about 20 feet it makes a loud klunk noise and keeps on going like nothing happened??? It sounds like its coing from the rear end, pumkin area? I thought it was the U joints, but the truck has 8700 hundred miles on it, its new! i took it to the deal this moring and he said the yoke was not sliding into the tail correctly, so he greased it up and said it was fine. i went down the road and backed up and klunk??? I took it back and there it sits! Been there all day and I called them tonight and they said, well we cant get it to make the same noise so we dont know??? does anybody have a clue????? Im lost and worried cause I dont wanna leave it there for days on end. The good part is I arrgued with the dealer and they gave me a 04 GMC plow truck for a rental!!!!!! HELP!!!!!!, thanks..................:dizzy:

    The problem with the slip yoke not sliding properly on the tailshaft occurred on 99-02 trucks. GM corrected the problem by going to a nickel plated slip yoke. Make sure you have the service manager document your complaint. Take the service advisor for a drive and duplicate the problem for him. The noise is definitely not normal.

    I had the same problem, and it was the slip yoke. They lubed it up and it when away. I do believe there is a TSB on the subject and I believe that the nickel yoke was a remedy. For me the klunk went away and it has been fine ever since.

    Just got my truck back they did do the yoke trick and it still did it. They tried and tried but found nothing, the only thing we can think of was there was snow and ice packed around one of the brake calipers and was hold it back from releasing and then it would return causeing the klunk or ding noise?? Who knows Ill keep driving it and if it snows we will see if it returns, thanks for the help, I ll keep ya posted!!!
