Mercedes-Benz C-Class lower control arm noise causes: It may be due to the cracking of the upper control arm bushing, allowing foreign objects or excessive dirt to enter, resulting in noise when turning. Control Arm Introduction: A control arm is a mechanical tool, specifically referring to the multi-link suspension. Through different linkage configurations, it allows the suspension to automatically adjust the camber angle, toe angle, and provide the rear wheels with a certain steering angle during compression. Control Arm Working Principle: The principle involves designing the constraint angles of the connecting motion points so that the suspension can actively adjust wheel alignment during compression. This design offers great flexibility, allowing for complete matching and tuning tailored to the vehicle model. Therefore, the multi-link suspension can maximize tire grip, thereby enhancing the vehicle's handling limits.

How to switch driving modes in Mercedes-Benz GLC?

The method to switch driving modes in Mercedes-Benz GLC is: While the car is running, use the small mouse in the central control area or the multifunction buttons on the steering wheel to locate the driving mode option in the vehicle computer, then you can make the change. The Mercedes-Benz GLC has four driving modes in total: eco mode, comfort mode, sport mode, and sport+ mode. When the car is in eco mode, the throttle response slows down, and the car's power is reduced to achieve fuel-saving. In comfort mode, the car's transmission and throttle response are balanced, with moderately firm suspension, providing a comfortable driving experience. In sport mode, the car's chassis becomes stiffer, the transmission and throttle response speed up, and gear shifts occur later to deliver higher power. In sport+ mode, the car's chassis is at its stiffest, enhancing stability during high-speed cornering, and the transmission keeps the engine in a higher RPM range to maximize the car's power output.

Can I apply for a car license plate if I have a motorcycle that hasn't been scrapped?

If you have a motorcycle that hasn't been scrapped, you cannot apply for a car license plate. According to relevant regulations, if there is any motor vehicle under the owner's name that has not passed inspection or has not been scrapped on time, the system will automatically lock it. Only after the owner completes the vehicle inspection or the scrapping procedures can they proceed with new vehicle registration, transfer registration, and other procedures. The following are some precautions regarding vehicle license plate application: 1. Determine the type of license plate to apply for: After deciding whether to apply for a local or out-of-town license plate, pay the purchase tax according to regulations. The vehicle purchase tax should be paid at the vehicle's registered location. If you choose a local license plate, the tax must be paid locally; if you choose an out-of-town license plate, the tax must be paid out of town. 2. Fully understand relevant information: Before purchasing a new energy vehicle, determine whether a charging pile can be installed and understand relevant information. You should also learn about the application process for special license plate quotas, fiscal subsidy standards, and other important information.
