Diagnosing Whining Noise When AcceleratingMany automotive noises creep up on you. Then you start to wonder how long this has been going on before you noticed. Automotive noises can stress you out. The car seems to be working fine, but you know something must be going wrong. How serious is it? Is the car unsafe, or is it going to let you down somewhere? Interpreting automotive noises is often a matter of experience so the amateur mechanic is usually at a disadvantage because their experience is usually limited to the cars that they or their family own. But there are a few symptoms that are common across a range of cars and a few logical checks can help you figure out what is going on. Step 1: Ruling out engine noise. Race the engine gently with the car in Neutral and listen carefully for any signs of the offensive noise that are associated with the engine speed. With a few exceptions, a noise that occurs when the car is shifted into gear is most likely associated with the transmission. Step 2: Manual or automatic. If your car has a manual transmission, the sounds that it makes can mean entirely different things from an automatic. Does the sound occur when you put your foot on the clutch to shift into gear? Then you probably looking at a release bearing, which means clutch replacement. Does the sound occur as the car just starts to move as you release the clutch then go away when the car is in motion? That would be a pilot bearing, which also means clutch replacement. A manual transmission is only turning when the car is either in motion, or when the transmission is in Neutral and the clutch is engaged your foot is off the pedal. So sounds that occur while the car is stationary and in gear are most likely associated with the clutch. Whirring sounds that occur while the car is in motion may indicate transmission bearing noises or driveline noises.
