What is an inspection for squealing noise when steering wheel is turned?

During an inspection for a squealing noise when the steering wheel is turned, a mechanic will inspect your vehicle to determine the cause of the noise. Typically they will check out your power steering fluid, power steering pump, and engine belt.
Most modern cars are equipped with power steering. If you are hearing a squealing noise when you turn the steering wheel, you’ll need to consult a mechanic for an inspection. The squealing sound indicates a problem with your car’s power steering system.

How to repair a squealing noise when steering wheel is turned

When a mechanic performs a squealing noise when steering wheel is turned inspection, they will check out the following issues:
  • Low power steering fluid: The squealing noise heard when you turn the steering wheel could mean the power steering fluid is low. Often, low power steering fluid levels are caused by a leak. The mechanic will check underneath the car’s engine for red or pink fluid leaks.
  • Failing power steering pump: Squealing when turning the steering wheel can be a sign of a failing power steering pump. Seals and other components of the power steering pump wear down over time, making it difficult to maintain a consistent level of fluid pressure. A worn-out pump will eventually stop working completely, resulting in steering that feels very heavy.
  • Worn-out belt: The power steering system gets its power from an engine belt. When a belt gets worn or slips out of place, it can generate a squealing noise as the steering wheel is turned. A worn-down belt affects the fluid pressure created by the power steering pump and once the belt snaps, the power steering pump fails to function, and steering starts to feel extremely heavy.
Typically, the mechanic will begin their inspection by opening the hood and inspecting the engine bay, looking for damage to the power steering pump or belt. The mechanic will also look at the power steering fluid levels and check for leaks.
Any worn or broken components of the power steering system will be replaced. All new parts will be tested before you leave the auto body shop to ensure that the squealing noise when turning the steering wheel has been repaired successfully.
