SOURCE: Alero loud humming/roaring sound coming from front end.

That's indicative of a wheel bearing, which is why you were told to change that out. However, it's also possible that the carrier bearings in the differential (where the drive axles attach) have gone bad. That happened to me on my 300ZX several years ago, and I had to replace the diff bearings. I would have them checked out somewhere other than a dealer (you'll probably get a better price from an independent shop).

As a sidenote, to be sure it wasn't a wheel bearing, if you hear it quiet down in a turn one way but get louder in a turn the opposite way, it's likely the wheel bearing. If you turn left at speed and it gets louder, then it's the right bearing (since you're loading up that side of the car). If it gets quieter in a right turn, it's the right side (you're unloading that side of the car and not putting as much weight on it, so it doesn't drag as badly). See if you get that symptom just to be sure that the wrong side front wheel bearing wasn't changed.

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.

most likely if its a hum it could be tires , if its a roar it could be the drive train

There is a humming sound coming from the front end of my 1999 oldmobile alero. Only happens when the car is moving. I dont hear itat idle or even when pushing the gas at idle. could it be my transmission...


Hello! If the humming noise is speed related(gets louder as vehicle speed increases)check front wheel bearings. If the noise goes away when turning one way or the other then it will most likely be in the front wheel bearing. If you turn the wheel(while moving)to the right and the noise goes away it is on the right side. If you turn the wheel to the left and the noise goes away its on the left side. Hope this information helps!

Humming noise in the front end


Does the noise change pitch when you weave the wheel back and forth at 25. If yes you need bearings. I think they are pressed in on focus

Had the same problem 2 weeks ago


well if the radio is locked (like says locked right on the radio) then you can take it to a dealership and have them unlock it for a small fee.... like 5$. they get a code and put it in to unlock it.

Loud humming noise from front end of Durango 4 x 4


You have a hub/wheel bearing going out. You need to jack up the vehicle on each side. Grab the top and bottom of the wheel and try to move it in/out at the top and bottom. If this does not work then roll the wheel as fast as you can and see if you can hear which one it is. Good Luck.

Noisey front end


Change the tire. Your tires might be worping from the inside. I had the same problem. It might need an aligment too.
