What causes the noise when turning the steering wheel while stationary?
3 Answers
The reasons for noise when turning the steering wheel while stationary are: 1. Lack of lubrication in the steering column, causing high friction; 2. Check if the power steering fluid is low; 3. Inspect the universal joint for any issues; 4. Aging and hardening of the rubber bushings in the chassis suspension stabilizer bar links; 5. Damage to the thrust bearing. Relevant information about the steering wheel is as follows: 1. Introduction: Generally connected to the steering shaft via splines, its function 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. 2. Usage considerations: When using a larger diameter steering wheel, the force required from the driver's hands can be reduced. The steering intermediate shaft, as a connecting component between the steering gear and the steering shaft, facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and ensures more rational installation of the steering gear and steering wheel in the vehicle.
I've also heard strange noises when turning the steering wheel while stationary in my previous car, most likely due to an issue with the steering system. The most common causes are insufficient power steering fluid or air bubbles in the hydraulic lines, which can make the pump produce squealing sounds during operation. Tire wear or uneven road surfaces may also amplify the noise, but the core problems are usually loose steering linkage or worn ball joints. This is no trivial matter, as sudden steering lock-up while driving could lead to an accident. I recommend you immediately check the power steering fluid reservoir and top it up if the level is low. If the noise persists, don't delay—head straight to a 4S shop or repair garage for a thorough inspection. Safety comes first. Regular maintenance is crucial; change the power steering fluid every two years to prevent aging-related issues from accumulating.
To be honest, diagnosing strange noises when turning the steering wheel while stationary requires a step-by-step approach. First, check if the power steering fluid level is low or too dirty - low fluid levels can cause the pump to make noise. Then try to identify the source of the sound: if there's a creaking noise coming from below the steering wheel, it might indicate worn tie rods or ball joints; if the noise comes from the chassis, it could be related to shock absorber issues. I recommend testing with gentle steering wheel turns on flat ground - avoid aggressive turning to prevent vehicle damage. When I encountered this problem myself, I found that replacing deteriorated fluid immediately solved the noise issue. Also remember this problem occurs more frequently in winter because cold fluid becomes thicker and flows poorly. If you're unsure, act within your capabilities and get it repaired early to prevent minor issues from becoming major ones.
