Causes of a Steering Wheel Whine
Power-steering systems use hydraulic fluid to steer the wheels on a vehicle. When there is a problem with this system, its steering rack, belt or pump will make noise. The noise can eventually lead to rough turns and a damaged steering system. Listed are common issues that cause whining noise in a steering system.
Worn belts are the usual culprit when there is a whining noise present. To check the belt, inspect the tension. If too tight or loose, the belt will whine when spinning. Also check to see if the ridges of the belt are worn. Worn ridges will cause the belt to slip while spinning, which can also contribute to the noise.
Air in the System
Another cause for whining noise is air in the steering system. When there is air in the steering hoses, hydraulic fluid does not flow correctly through the system. This results in rough steering and whining noises. To repair this, bleed the power steering system and replace the fluid.
A failing pump will not push the hydraulic fluid through the system. This will make it difficult to turn and will sometimes cause the pump to whine, as it may be low on fluid.Learn more about Car Parts & Maintenance
If the front end of a car makes a squeaking noise when the wheel is turned, this indicates a problem with the wheel bearing, suspension or the power steering system. The first thing to check is the power steering fluid. When the fluid is low, the steering makes a noise.Full Answer >
A grinding noise during a turn is typically a sign of a failing constant velocity joint on a front-wheel-drive car. The constant velocity joint provides power to the front wheels, allowing the car to turn.Full Answer >
To flush a power steering system, first elevate the front wheels of the vehicle and put a container beneath the power steering system to catch drained fluid, and then let the old fluid out, and refill the system. Circulate the new fluid throughout before flushing and bleeding the system.Full Answer >
To perform a power steering system flush, gather all the necessary tools and materials, then prepare the vehicle. Once the vehicle is ready, completely drain the old fluid from the system, then refill it with new fluid. Run the new fluid through the system, then drain it out. Refill the system again, and purge any trapped air in the system.Full Answer >
