Squeaking Noise When Turning the Steering Wheel
A squeaking or groaning sound when turning the steering wheel -- particularly at low speeds or at full lock -- often points to the power steering system. The most common cause is low power steering fluid causing the pump to cavitate. On electric power steering systems, a squeak may come from the steering column intermediate shaft or tie rod end.
What Causes This Sound?
- • Low power steering fluid allowing the pump to cavitate and generate noise
- • A worn or failing hydraulic power steering pump with a damaged vane or pressure ring
- • A dry steering column intermediate shaft (U-joint or slip yoke) needing lubrication
- • Worn tie rod ends or ball joints creating noise under steering load
- • A worn steering rack and pinion with insufficient internal lubrication
Drive with Caution
A failing power steering pump can leave you with suddenly heavy steering, making the vehicle difficult to maneuver safely, especially at parking speeds.
Power steering pump noise is common on high-mileage F-150 trucks with hydraulic systems; Silverado trucks develop intermediate shaft squeak; Toyota Camry hydraulic and electric systems develop noise at different wear points.
