Vibration in a 04 Sierra

justjoshin · 03-06-2016, 10:11 AM

Ok guys,

Like the title says I have a vibration in my 2004 GMC Sierra 2WD extended cab 4.8L. It is one of those seat of the pants / all over the truck things and not in the steering wheel. Thought maybe a balance issue so had the tires checked and rotated. Shop said balance was good and no change after. Thought maybe shocks but they aren't very old and it is a rapid vibration and not a bounce, so not sure if that could be it. I looked online and found one forum where a guy wrote about a similar issue and it ended up being the drive shaft carrier bearing. I am thinking of having it changed along with the u-joints due to the age and having 130k miles anyway. With all the info and help I always seem to get on this site for the Camaro I figured I would see if anyone might have some thoughts. Thanks for any help in advance!

Driveline vibrations definitely would be felt throughout the vehicle, U joints and carrier bearing can cause these, but so can a pinion bearing, but that usually ends up first becoming a noise you'll hear inside. Safe bet would be having u joints and carrier bearing replaced.

thanks, I have not heard any noises so I hope changing the u-joints and bearing will cure things.....

Agreed had a similar issue with my old avalanche. Turned out to be u joints.

Ended up getting under the truck and found a lot of slack in the bearing. Weird thing was i went to the dealer to get it replaced and they wouldn't give me a price up front, said that they had to diagnose it? Why do they have to diagnose something that I want to have them replace? In the end it was the bearing.
