What to Do When Unable to Identify the Source of Car Chassis Noise?

[McViolet]

Here are the possible causes and suggestions for chassis noise: 1. Shock absorber noise, which can be heard on uneven roads or during turns. It is recommended to replace the shock absorber. 2. Due to the balance bar rubber sleeve breaking or loosening because of suspension noise, it is advised to check if the balance bar rubber sleeve is loose. 3. Suspension rubber sleeve breakage or loosening. It is recommended to inspect the suspension for any issues. 4. Disc brake noise. This occurs when the brake shoe support plate, damping spring plate, or guide plate of the disc brake is damaged, deformed, or detached, increasing the gap between the brake shoe and the caliper support frame, causing them to collide and produce noise. Visit a repair shop to fix the deformed parts or replace the detached components. 5. Front suspension ball joint noise. The gap between the ball joint and its seat becomes larger, leading to severe looseness. Since the ball joint seat is a sealed structure and cannot be disassembled, the only solution is to replace it at a repair shop. 6. Front wheel shock absorber noise. This is usually caused by driving on rough roads and improper maintenance, resulting in oil leakage and damage to the shock absorber. Depending on the severity of the damage, it may require repair or replacement. 7. Drive shaft universal joint noise. This is due to excessive play or jamming in the universal joint. The main reasons for noise in the universal cross shaft are the lack of lubrication or delayed maintenance. In such cases, visit a repair shop for greasing or repair.
