How to Solve the Problem of Steering Wheel Noise?
3 Answers
When there is noise while turning the steering wheel, it is necessary to check whether the half-shaft CV joint is worn. Disassemble and inspect the inner walls of the left and right inner CV joints for wear and pits. In most cases, the issue is caused by the contact points between the inner CV joint walls and the outer surface of the ball bearings, which are the torque transmission areas. During daily use of the vehicle, pay attention to the following precautions: 1. Avoid turning the steering wheel while the vehicle is stationary; try to steer only after the vehicle starts moving. 2. After the vehicle is parked, return the steering wheel to the central position to prevent the suspension system and tires from bearing unnecessary load. 3. When making a U-turn, try to avoid turning the steering wheel to its extreme limit.
I've encountered the issue of hearing strange noises when turning the steering wheel several times. The most common cause is insufficient lubrication in the steering column dust cover, especially noticeable in winter—applying some grease immediately quiets it down. If there's a clunking sound when turning the wheel while stationary, it's likely the thrust bearing is damaged; that part can't withstand impact forces and needs replacement. A hissing sound under the steering wheel calls for checking the universal joint clearance or the steering motor gears—last time my car had worn gears, costing 800 bucks to replace the entire assembly. If the noise only appears on bumpy roads, focus on the suspension arm bushings; cracked or aged rubber will produce squeaky sounds. Additionally, a whining noise when turning the wheel to full lock often indicates the power steering pump is failing. Remember to check the power steering fluid level weekly—low fluid can also cause noises. Don’t wait for the problem to escalate; replacing the entire steering system can cost thousands.
My old car's steering wheel had strange noises and it took three repairs to figure it out: The first time, the floor mat was stuck on the steering shaft, and moving it away fixed the issue. The second time, the repair shop found a loose lower control arm ball joint, and replacing it cost over 300 yuan. The most recent issue was the most troublesome—there was a metal grinding sound when turning. The mechanic disassembled it and found the steering column bearing was rusted and lacked lubrication; applying grease immediately solved the problem. Daily care is essential for the steering system, especially avoiding holding the steering wheel at full lock for too long, as it can damage the power steering pump. Slowing down over speed bumps can extend the lifespan of chassis components. I have the shop spray rust-proofing agents on the steering gear rubber boots every six months, which can double the lifespan of rubber parts. Additionally, modifying the steering wheel may disrupt the factory settings, so non-professional modifications should be avoided.
