If it's a manual it's supposed to whine when reverse is used, if it's an automatic it probably just needs transmission fluid.
That is just the sound of your linkage cable going in reverse. all cars have that same noise just different volumes
if the noise is a high pitched squealing noise, the belt is slipping....if the noise is a whine or growling noise, the pump is low on fluid or the pump is bad
yes the alternator can generate noise or whine in the speakers.
Your throw out bearing is the problem.
The belts generally don't make a whining noise. They squeak. The whine is probably the tensioner or the alternator. Listen closely you should be able to tell where the noise is coming from. You can also take off the belt and roll each component and feel for bearing crunching.
because the reverse gears are designed differently. Because you don't use reverse as much as the other gears it's make cheaper, so it ends up making a whine while you back up. hope this helped
Diff whine
If it is like a whirring whine that is probably a normal 4X4 noise. Any other noise I'd be looking into as a problem.
If the noise sounds like a power steering whine it could be caused by the A/C compressor clutch bearing or the belt idler pulley.
IT MAY NOT HAVE A CHOKE BUILT INTO THE CIRCUITRY. YOU CAN BUY A NOISE SUPPRESSOR AT RADIO SHACK. THIS SHOULD ELIMINATE MUCH OF THE ALTERNATOR WHINE NOISE. GOOD LUCK! ...BB
Sometimes, but not always, the alternator will whine loudly when it's malfunctioning.
