Probably slight wear due to lack of oil changes.

It is important to change all the cars oils and fluids periodically.

Prevention is always better than cure.

Whining noise when extreme cold days, that goes away when my 2005 Mariner warms up. Seems to come and go until the car warms up.

Alternators can sometimes whine when start up on a cold morning, they run on full load till they get the battery back up to full charge. When the whining stops, switch on electrical equipment (Headlights, fan full boost, heated rear window) if the whining starts again its the alternator.

There is a humming or whinning sound coming from my 1998 ford expedition while im driving. The sounds stops when i take my foot off of the accelerator.

if the sounds is comming from the rear sounds like crown and pinion is worn out , the crown and pinion in the rear diff will only hum or whine under load while in contact and when you let go the pedal there is no load equalling no noise. you can replace the crown and pinion but you do need some specialty tools like dial guages and spreaders and pinion depth guage

How do I get to the throttle body to fix accelerator spring? The accelator cable whines at high acceleration and will continue to accelerate, but will not decelerate below a certain (whining) point.

im not 100 percent sure about your problem discreption, but give it a good spraying of wd-40 cleaner/lubricant, available from any hardware or automotive store.

Whining diff on drive nissan terrano 1995

I would have someone check the U-Joints on the drive shaft. When they go bad they will cause a vibration when you are driving down the road. Taking your foot off the throttle stops it because the torque is being applied to/by the driveshaft any longer.

Good Luck

Whining sound from under van only when i push the gas.

The serpentine belt is the most common cause for whining sound when accelerating, try to understand if noise is coming from serpentine belt.

Also check power steering belt under steering column, and also the rotor and chain, thei do not make whining noise , but can make noise when accelerating.

The belt is first suspect.

hi these boxes tended to be a bit noisey anyway but a simple test for the release bearing and first motion shaft is easy first make sure g/box oil level is ok
start engine ,take your foot off the clutch peddle compleatly you have a whine, put your foot on the peddleVERYlightlynoise should change ,if the noise is more of a rattle than a whine it is coming from the clutch release bearing if it a definate whine it is either the spigot bearing in the flywheel or the first motion shaft
