I have a loud humming noise comming from the front end of my 1996 pontiac sunfire constantly help please.


Does the humming noise reduce or change in pitch slightly when turning a corner?
Most likely a wheel bearing failure. Also, when one wheel bearing on one side fails, the other is not often far behind. I often therefore replace in pairs.

JUST GOT TWO NEW FRONT TIRES,(AND BALANCING). NOW THERE IS A CONSTANT NOISE COMING FROM THE FRONT END AND GETS LOUNDER AS ITS ACCELERATED. SOUNDS LIKE A RUBBING OR HUMMING NOISE.


Sounds like a wheel bearing or bearings going bad.

Humming or 'howling' noises are indicative of a bad wheel bearing especially on acceleration.

Good luck on this repair.

Humming in the front end, with a louder noise when turning.


Check your front wheel bearing and hubs when they defect the sounds increase on turns from one side to the other, due to the weight(load) displacement loaded on the bearings.
If your vehicle has front wheel drive this also can be the beginning of a defective front axle/axles C.V. joint(constant vellocity joint).

Humming noise in front end of truck


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?
