What Causes the Steering Wheel to Make Noise When Turned to Full Lock?
2 Answers
Car steering wheel making noise when turned to full lock is caused by: 1. Aging or malfunctioning steering gear; 2. Poor lubrication or damage to the plain bearing; 3. Aging bushings or ball joints on the suspension. The solutions for a steering wheel making noise when turned to full lock are: 1. Replace the steering gear; 2. Replace the plain bearing; 3. Replace the bushings or ball joints on the suspension. The function of the steering wheel is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft to achieve the purpose of changing the vehicle's direction. Steering wheels are categorized into: single-spoke, double-spoke, triple-spoke, and four-spoke steering wheels.
I've experienced abnormal noises when turning the steering wheel to its limit while driving, which usually indicates a problem with the steering system. For example, worn steering ball joints can produce friction sounds at extreme angles. This might be caused by frequently turning the wheel to its limit during daily driving, especially when applying extra force during sharp turns, which accelerates wear. Another possibility is insufficient power steering fluid or air entering the hydraulic system, causing loud pump operation. Ignoring this issue may affect steering precision over time and even lead to safety hazards. It's recommended to briefly check the steering wheel's range of motion before each drive and avoid holding it at full lock for more than three seconds. Regular maintenance at professional service centers to inspect the power steering pump and suspension components is advisable to ensure everything functions properly. This approach not only resolves the noise issue but also extends the vehicle's lifespan.
