Low Power Steering Fluid: Check the power steering fluid level. If it's low, adding more fluid may help reduce the noise.
Faulty Power Steering Pump: A worn-out or failing power steering pump can create a whining noise. The pump supplies pressurized fluid to the steering system, and when it's not functioning properly, it can result in this type of noise.
Air in the Power Steering System: Air bubbles in the power steering system can also cause a whining noise. This can happen if the system has been recently serviced or repaired, or if there's a leak in the system.
Worn Steering Components: Other steering components, such as the steering rack, tie rods, or ball joints, can also develop wear and tear over time, causing a whining noise when turning.
It's important to have your vehicle inspected by a qualified mechanic to identify the exact cause of the whining noise and ensure that the power steering system is functioning properly. Ignoring power steering issues can lead to more costly repairs down the road.
