Here are the reasons for a sudden scraping metal sound from the car's chassis: 1. Disc brake noise: This is caused by damage, deformation, or detachment of the brake shoe support plate, vibration damping spring plate, or guide plate of the disc brake, which increases the gap between the brake shoe and the caliper support frame, leading to mutual impact and noise. You can go to a repair station to fix the deformed parts or replace the detached ones. 2. Front suspension ball joint noise: The gap between the ball joint and its seat becomes larger, causing severe looseness. Since the ball joint seat is a sealed structure and cannot be disassembled, in this case, you can only go to a repair station for replacement. 3. Front wheel shock absorber noise: The vehicle is usually driven on rough roads with improper maintenance, causing the shock absorber to leak oil and become damaged. At a repair station, the severity of the damage will determine whether it needs repair or replacement.
