Whining when accelerating

My 2002 makes a whining noise when I accelerate. It gets louder as the vehicle warms up. The SF is telling me the rear differential needs lubrication. How do I do that?

My 2005 Chrysler town & country is making a whining noise and gets louder when I accelerate. Also my light is on for rear defroster, but it doesn't defrost. Help!!!!!!


If the whining noise is coming from under the hood, have all pulleys checked for wear. ( Alternator/tensioner/idler etc ). A bad pulley will whine. As for the rear defrost, check the wires that go to the back window. There will be one on each side of the rear glass. One may be seperated/broken from the glass causing the defrost not to operate

1999 Mitsubishi Eclipse whining noise from the rear when accelerating


A whining noise during acceleration usually, is from the gear set, indicating the pinion is too close to the ring gear.
I believe the eclipse is a FWD car though. Could it be the transmission you are hearing?

My 52 mini suddenly started making a whining noise, its an automatic, i didnt get any any warning it ciasts fine and reverses but once you put your foot on the accelorater the whining noise slows the car...


Check your transmission fluid level, as recommended in the Owner's Manual. Also, if your car is equipped with power steering, check the fluid level in the power steering reserve.

If all fluids are at recommended levels, see if you can locate the noise. If it is in the engine compartment, try to determine if the noise is coming from any of the serpentine belt pulleys.

Sometimes the bearings on air injector pumps fail in higher-mileage vehicles, first causing a "whining" noise, and ultimately resulting in the serpentine belt "chirping" or squealing on acceleration. Best you can do is make sure all fluids are at recommended levels, then try to pinpoint the source of the whining noise for further diagnosis.

Hope that's helpful!.

'05 Chevy Colorado has an engine whine coming from rear of engine block on passenger side. Took the drive belt off and the whine is still there. The more I accelerate, the louder the whine.


There is nothing that can make a whining noise in the back of the engine. Likely the noise you hear is coming from either the transmission converter or pump. Before anything else is done, check the fluid level. If the fluid on the dipstick smells burned, you definitely have an internal trans problem.

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.
