car is whining

[rezaa]

there is a whining noise i can hear from the rear of the car when i accelerate.

what could it be

[edino]

Difficult to tell without elaborative information like milage, age, maintenance record etc. Normally whining indicates an irreversable problem unless repair is done. Cound be wear and tear, lubrication problems, or mis adjustment of the gear wheels. Service attention to find the root cause is the only answer.

Having said this, many cars can do lots of milage with whining differentials or gears with no reliability issues for a long time.

best is to have a professional look at it and determine the root cause. This will tell if seriuos or not....
