HUMMING NOISE FRONT DRIVERS SIDE AT 50MPH AND SLIGHT VIBRATION

SOURCE: loud humming noise from drivers side front end

humming noise usually comes from wheel bearings. did you change that with a new bearing? also choppy or worn tires can cause humming noise that sounds like bad wheel bearings. rotate your tires and see if the noise changes. if so its tires. also even if it sounds like its from the right it could very well be a bad bearing in another location.

I'm having the same problem with my 2006 Chevy 2500 duramax...The humming starts at 25mph and then gets less prominent and then at 50mph it gets more prominent and louder, then at 60mph you can hardly hear it.....I did notice a little bit of leakage where the front axel meets the from diff on the drivers side.
Any suggestions?

SOURCE: Vibration/Humming/Grinding noises when stopping or turning left.

when turning left vehicle distributes weight to right front wheel bearing causing load. since u describe a noise in right front while driving straight i would suspect failed right front wheel bearing. see if your noise changes/goes away while turning right that should tell u 4 sure

One of the front wheels isn't balanced correctly and its vibrations cause a resonance in the suspension at that speeds. You might also have a look at the shocks - if you have fitted new tires their hardness and misbalance might bring out the weaknesses in the shocks : these vibrations might be the first sign the shocks have aged and will soon have to be replaced.
You just need to have all the wheels balanced and the bushings of the suspension inspected at a tyre shop - a 30 minute/$50 simple job.
