Should the cracked front wheel liner be replaced?

If the damage is minor, it is recommended to repair it. In severe cases, replacement is advised. The fender is the outer body panel that covers the wheel, designed to comply with fluid dynamics, reducing the drag coefficient to ensure smoother driving. More detailed explanations are as follows: 1. The front fender is installed near the front wheel and must ensure the maximum clearance for wheel rotation and movement. Therefore, designers use 'wheel travel diagrams' based on the selected tire model and size to verify whether the fender's design dimensions are appropriate. The rear fender does not face issues with wheel rotation interference, but for aerodynamic considerations, it is slightly arched and protrudes outward. Nowadays, some car fenders are integrated with the car body, manufactured in one seamless process. 2. Additionally, the front fender helps prevent gravel and mud splashed by the wheels from reaching the undercarriage during driving, reducing damage and corrosion to the chassis. Therefore, the materials used must be resistant to weather aging and have good formability. Currently, many car front fenders are made of elastic plastic materials, providing a certain level of cushioning for enhanced safety.
