What Causes the Steering Gear Noise in Audi A5?

[MacWeston]

The causes of steering gear noise in Audi A5 include prolonged lack of maintenance on the steering knuckle, long-term stationary steering, and wear and aging of the steering gear. Prolonged lack of maintenance on the steering knuckle: The main issue lies in the prolonged lack of maintenance on the steering knuckle, which leads to severe oil deficiency, wear, or even burning of the steering column and bushings, resulting in heavy steering and noise. Long-term stationary steering: This not only places a heavy load on the steering gear but also accelerates the wear on the tire surface, reducing the tire's service life. Wear and aging of the steering gear: It is advisable to develop the habit of steering only after the wheels start moving, which reduces the friction resistance between the tires and the ground, alleviating excessive load on the steering gear and excessive wear on the steering linkage system.
