What is a loud roaring sound on front end of 2000 chevy cavalier while driving?
Bad front wheel bearings will make a loud roaring sound, and get louder as time goes by, check this out! God-Bless!
Testimonial: "had that checked already. not the problem. thank u anyway."
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.

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub
SOURCE: wheel noise or roar in front end with increased road speed
THIS NOISE IS USUALLY THE HUB. HAVE SOMEONE GO WITH YOU ON A TEST DRIVE. GET THE ROARING TO HAPPEN AT ITS LOUDEST AND GENTLY SWERVE THE CAR LEFT AND RIGHT. DON'T BE SURPRISED IF YOU THINK BOTH HUBS ARE BAD. LIFT THE FRONT OF THE CAR AND PUT IT ON JACK STANDS. PULL OUTWARD ON THE BOTTOM OF THE TIRE WHILE PUSHING INWARD ON THE TOP OF THE WHEEL. IF THE WHEEL MOVES EXCESSIVELY YOU FOUND THE HUB THAT IS NOISY. USING A MECHANICS STETHOSCOPE YOU CAN SOMETIMES HEAR A ROARING TYPE NOISE ON THE BACKING PLATE SIDE OF THE HUB WITH THE ENGINE RUNNING AND THE TRANS IN GEAR. TRY NOT TO GET THE SPEED UP TOO FAR ESPECIALLY IF YOU CAN HEAR THE NOISE AT LOW SPEED, YOU DON'T WANT TO VIBRATE OFF THE STANDS.

it sounds like a bad hub bearing
try raising the front end off of the ground and spin the tires by hand and feel for roughness in the hubs
