The reasons for the abnormal noise when the GLC steering wheel is turned to the limit while moving forward are: 1. Friction between the steering column and the floor mat; 2. Faulty clock spring inside the steering wheel; 3. Aging or excessive play in the steering tie rod ball joint; 4. Leaking dust cover of the steering gear; 5. Steering gear failure; 6. Lack of lubrication in the shock absorber's thrust bearing. Both the GLC 260L Sport and Luxury models are equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 197 PS, a maximum torque of 320 Nm, and a maximum power of 145 kW. The body dimensions of the GLC 260L Sport and Luxury models are: length 4764 mm, width 1898 mm, height 1642 mm, with a wheelbase of 2973 mm.
I've encountered a similar situation when driving my GLC - it makes clicking noises when turning the steering wheel to full lock while moving forward, which is quite annoying. Based on my experience, the main causes could be wear in steering system components, such as loose universal joints or excessive load on the power steering pump leading to abnormal sounds. Keeping the steering wheel at full lock for extended periods increases mechanical stress, accelerating part wear. Additionally, the GLC's suspension design causes increased tire friction noise at extreme steering angles, though it's not entirely due to the Ackermann effect (which typically causes issues during low-speed turns). I recommend avoiding frequent full-lock steering and leaving some space when parking. If the noise persists, visit a dealership immediately to check the tie rods and suspension - addressing minor issues early prevents major repairs, ensures driving safety, and saves on maintenance costs.
