Front End Humming Noise - Help!

[Hyper_Tahoe]

Hello all. I need some help. My 2003 Tahoe is making a humming noise from the front end. I have gone through this before and figured it was a wheel bearing. I had the right side replaced a few years back. The sound is audible over 20mph and definitely at highway speeds and when decelerating. I tool it to a local shop. They put the truck on the lift and performed the normal tests. There was no noticeable play. I hear the noise while driving and when turning to the right. When turning left, weight transferred to the right side, the sound goes away. I figured it was the front left wheel bearing. I just had it replaced, and the sound is still there. Maybe not as loud as before, but still noticeable. Any ideas or suggestions?

I do have 4wd. What are symptoms for a bad U Joint?

I had the same thing happen. Turned out to be bad wheel bearing. I replaced both hubs at the same time, but your left to right example means its more than likely the older hub finally going bad. Mine had a dull roar to it and when the weight shifted off the bad bearing it would stop.

symptoms would be high pitched squeaking, popping sounds when going into gear, along with funky vibrations....

Bottomline2000 you are right. I changed the right hub bearing Monday and the sound is gone.

Mine is making same humming noise but when I get about 30 mph and decelerate or just let off of accelerator above that speed and when slowing down. So basically just needing to replacing both from bearings? What about U joints ?
