- A worn-out wheel bearing can cause a whining or growling noise when the wheel is rotating, especially at higher speeds.
- When the vehicle slows down, the bearing stops whining.
- A dry or worn serpentine belt can also produce a whining noise when accelerating.
- This noise is usually more pronounced when the engine is cold and goes away after a few minutes as the belt warms up and becomes more pliable.
- Low transmission fluid can cause the transmission to overheat and make a whining noise when accelerating.
- The noise will usually go away once the transmission fluid level is restored.
- A faulty power steering pump can also cause a whining noise when accelerating.
- This noise is usually more pronounced when the steering wheel is turned, and turning it in the opposite direction will make the noise go away.
- Differential problems like worn or damaged gear or worn-out pinion bearings can also cause a whining noise when accelerating.
- This noise is usually more pronounced when the vehicle is turning.
