What is the reason for the abnormal noise when the GLC steering wheel is turned to the limit while moving forward?

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.
I think the abnormal noise when the GLC is turning at full lock while moving forward is mostly related to the chassis or drivetrain. When turning at full lock, the front wheels are at extreme angles, putting extra strain on the drive shafts or half shafts, which may cause friction sounds due to wear. Common causes include aging shock absorber top mounts or loose wheel hub bearings. If it's due to the Ackermann design, it's normal only under specific temperatures, but forward-moving abnormal noise indicates potential risks. I recommend paying attention to driving habits—avoid turning the wheel sharply while stationary. Regular maintenance checks on lubrication can extend component lifespan. If the abnormal noise is accompanied by steering stiffness, don't ignore it; have it inspected promptly to prevent accidents.
Steering wheel turned to the limit with abnormal noise is no small matter, and I'm concerned about potential safety hazards. It may indicate steering mechanism failure, such as damaged tie rod ends, which can reduce handling precision. In GLC models, this is commonly seen in older vehicles or those with high mileage, easily leading to loss of control risks. I recommend slowing down and pulling over immediately upon hearing abnormal noises, then checking tires and steering for obvious issues. Continuing to drive may worsen the damage and increase accident probability. The solution is straightforward: send for repair to replace worn components, and ensure suspension system inspection during every maintenance.
