Why does my power steering make a whirring noise?

Why does my rear differential make a whirring noise?
When the rear or front differential oil level is low whirring sounds can be generated as the metal of the differential is lacking lubricate. To check for this problem jack the car up using jack stands and check the fluid level.
Why does my AC make a loud noise when I start it up?
Outdoor fan motors and indoor blower motors squeal loudly when they’re going bad. The blower wheel and housing will also squeal when they malfunction. For some units, this sound is normal upon start-up. You should be able to identify whether it’s a sound that the unit always makes or if it’s something new.

Why does my car make a buzzing noise when I Turn on the AC?
If you’re hearing a car AC compressor noise while accelerating, or a buzzing noise when you first turn on your car’s air conditioner, you may have too much Freon in your system.

Why does the noise go away on a right turn?
The reason that the bearing noise goes away on right turns (or curves) is during that maneuver the weight of the vehicle shifts from the right to the left and that “unloading” of the right side wheel position takes some of the vehicle weight off of the right wheel bearing, usually just enough to make the noise go away.
