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: 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: diagram for 1998 buick lasabre serpentine belt

I found the diagram in my owner's manual.
I replaced the belt on mine just 2 days ago. All you need to do is remove one bolt from the lower motor mount and remove the spacer. After you relieve the belt tensioner, the belt will slip right through the gap. Don't forget to support the engine before removing the bolt. As a backup I took a photo of the belt with my digital camera beforehand... just in case.

I drive a 2011 Dodge Ram. When I start the truck it starts with a loud rotating noise. As I start to drive it has a very loud humming noise and gets louder as I accelerate.


Bad idler pulley (belt), bad alternator bearings, water pump..pretty much anything driven by the belt would be primary suspect. If all that checks out bad engine bearings are also a possibility. As well.

1998 Buick lasabre making noise coming from the pulley by the belts gets louder when cold


Most likely the belt tensioner pulley is worn out...(internally) and needs to be replaced...this is help on with one bolt in the middle of the pulley...be sure to align the back side of the new pulley with the slotted tip sticking out...one of the easiest to replace...about $50. for the part...inspect the new one to help familiarize yourself with how to mount it...use the end of your socket wrench to insert into the tensioner pulley to remove the serpentine belt...Hope this helps.

Loud clunking noise


yes you can have a bearing going out of a pulley,as far as you smelling oil burning you could have a valve cover leaking onto the exhaust manifold.

Loud rattling sound top of engine near or below the alternator when idling, goes away if accelerator is pressed


Hello: Remove the serpentine belt, see if the waterpump pulley wobbles/makes noise when you spin it. If thats not it then start the engine, belt still off see if noise is there also while engine is running see if vthe crankshaft pulley wobbles. Also check the A/C compressor pulley (engine off, belt off) spin it by hand and check for noise and wobble. If all the previous is ok then it could be the balance shaft front bearing and or the timing chain.

Serpentine belt tightener pulley bearing was bad, made a loud noise. I replaced the pulley (jobber part) and the noise level was reduced enough to notice the waterpump was also making a noise ... more revs = louder noise. I am now replacing the water pump. (approx 60k Miles too).

Loud pulley noise from A/C unit


For the price of a new pulley and bearing assy. and labor, it might be cost effective to get a remanufacterd unit and replace it yourself. When you tighten up the belt, don't overtighten.
