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: 2005 buick leSabre whine or humming noise from front end.

I had the same problem with my 2000 Buick LeSabre last year. Took it in and they determined the wheel bearing needed to be replaced. Costs about $300 per bearing, but definitely needs to be replaced as you'd be in serious trouble if the thing went out at highway speeds.

SOURCE: 1998 Ford Mondeo GLX, loud humming sound, front driver side.

Most likely it's a wheel bearing going out.., If you turn to the right, or the left when driving the noise will change pitch. Been there done that.....

SOURCE: My front end makes a loud humming noise.

Alignment will not create a sound by it's self. The most common cause of humming (especially if you have an agressive tread design)is a wear pattern in the tires...check for that or rotate the tires around & see if the noise changes. If it does then you know it's in the tires. & Not always, but most of the time a bearing noise will increase or decrease in intensity if you load up one side at a time by doing 35-50 mph & turning slightly to each side.

1996 ford contour loud humming noise and vibration from front wheels


You have a defective wheel bearing most likely, the noise sounds correct for that problem. have a shop drive it before you replace anything to confirm my guess.

Loud humming noise from drivers side front end changed hub assembly still have noise ????????????????


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.

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