SOURCE: noise in front end, sounds

You say the rear wheel axles and bearings have been replaced, you mention nothing of the front wheels, you have the symptoms of a front wheel bearing being worn out, remove them and check for pitting in the bearing rollers or the bearing races, I am sure you will find a problem. Hope this helps solve your issue with the bearing noise.

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: Loud roaring noise in front, steering wheel has vibration, replaced tires didn't help.

Wheel bearings are likly and I've changed many to solve this problem but it's esy to pick the wrong one with e vehical jacked and on jack stands suporting the car by the lower control arms ( normal ride hieght) run the car with a driver and listen to ti run , of course theres no load on the powertrain so there will be some lash ( power on to power decline ) cheack up. The roaring noise can be isolated by puting a sounding bar ( long metal rod ( sr=crew driver)) other against the part till the sound is rounded up rear but possible the carrier bearings in the (rear end) front drive. The axel bearings and on some units the carrier bearing thats in the CV axel on the block. Sounding rod will find and change the noisey part. Professional help is a good idea if you can't carry this out saftly

SOURCE: whinning/humming noise on front end

you have a wheel bearing going out. see if it gets quieter if you turn one way or the other that will tell you what side it is on
