What Causes the Steering Wheel Noise When Turning Left or Right in Hyundai Elantra?
1 Answers
The causes of steering wheel noise when turning left or right in Hyundai Elantra include drive belt slippage, power steering pump unloading idle, brake pad wear, and issues with the vehicle's steering system. Power Steering Pump Drive Belt Slippage: The power steering pump is driven by a belt. If the friction between the belt and the pulley is insufficient, the belt will slip on the pulley, producing a squeaking noise. Possible causes include an overly loose belt adjustment, excessive wear on the pulley groove, or a new belt not fitting well with an old pulley. It is recommended to visit a repair shop for adjustment. Power Steering Pump Unloading Idle: When turning the steering wheel, if the steering resistance is too high and exceeds the maximum pressure of the steering system, the power steering pump will unload and idle to protect the pump and steering gear. Typically, a squeaking unloading sound can be heard. This phenomenon is more noticeable when the steering fluid is dirty, the steering filter is clogged, or there is air in the steering hydraulic system. In such cases, professional repair is necessary. Brake Pad Wear: If the brake pads are worn to the limit and have started grinding against the brake discs, a noise will occur when turning. Replacing the brake pads will resolve the issue. Vehicle Steering System Issues: Friction between the steering rod and the power assist rod can cause noise. Solution: The vehicle should be lifted on a hoist for a thorough inspection of the chassis. Be sure to turn the steering wheel to its full lock before observation.
