Loud Squeeking

BAD2500HD · May 4, 2007

I have in the last two weeks or so had a loud squeeking noise from under my truck at first i thought it was the brakes but it seems to becoming from about the middle of the truck , lastnight i had my son walk along beside it as i was moving very slow and he said the same thing as i did , i even have it when the brake is on so any idear as to what it is ? would the drive shaft make any kind of sound like that ? Please Help ! as it is driving me nuts !!

If you have a two-piece drive shaft, it could be the carrier bearing.

hey man, i feel your pain. i had the same problem with my 06. you want believe what it ended up being. there is a grounding strap between the frame and body right by the cab bushing mounts that had rubber washers, i replaced these with regular washers and now i have no squeaks at all. i to thought it might be the brakes, or even the cab bushings maybe working their way loose but just the washers. go figure. check it out hopefully it is as easy a fix as mine was. lol, jd

Nope it doesn't have a two piece drive shaft , and i don't think its the body mounts but i will check them out , it's a sound that you can tell is turn ( hard to explain) around just if it was a brake but its in the center of the truck .

How about the front U-joint on the driveshaft?

It's dif. comeing from the rear of the truck my son talked to a guy he works with at a garage who used to work at a GMC dealership and told him it might be the rear U-joint , will the make noise before they go ? the shaft feels tight , there's no play in it so ?

Lloyd, did you find out the cause of the squeaking? I just developed the same charistics as you. I narrowed down to the drive shaft. The squeaking is so loud and the shaft helps by echoing, so it is difficuit to determine if it is the front u-joint, carrier bearing or the rear. My suspicion is the same as Peters, U-joint.

yeah when a universel joint goes its only readable by the human ears at low speeds aka walkin beside it while it rolls. but once you speed up idoes it seem to go away, because its funny if u cant hear it.. the neighborhood dogs with good hearing sure can haha
