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: Makes a low roaring noise when you are at crusing speed.

One of the front wheel bearings are bad. Jack it up and see if one is loose, the noise will usually change if you swerve back and forth while driving. Could also be a rear pinion bearing in the rear axle.

Why does my tacoma fan coil make a roaring noise


If the fan is connected to the water pump, it could be a fan clutch problem. The clutch is not supposed to kick in unless the engine is hot.

Roaring in the front end of my 2004 Chevy Trailblazer 4x4


A jet engine type of noise from the engine area usually means the fan clutch is going bad. I don't think the tach is related to this, that could be the stepper motor for the tach going bad.

Sounds like your fan blade clutch has seized up. This causes the fan to run @ engine speed @ all times. If thats not it I'll need more information

My 1988 chevy sport van makes a lot of noise when I drive down the road. It kind of roars from the floor area while driving down the road. Near the transmission area I think.


I think the fan clutch is locked up. With the engine off the fan should rotate by hand with a cold engine. When the engine heats up, the fan clutch locks up to cool the engine, and unlocks after it cools it down to approx 160 deg F. This is to help with fuel milage and noise.
