What Causes the Front Wheels to Make a Thumping Noise on Rough Roads?
2 Answers
The reasons for the front wheels making a thumping noise on rough roads are: 1. Damage to components such as the front control arm, front shock absorber, stabilizer bar bushings, or lower control arm; 2. The buffer rubber of the front wheel shock absorber has aged and hardened. This situation is normal, and the aged buffer rubber of the front shock absorber can be replaced. Rubber products will harden over time due to aging, and once hardened, they may produce abnormal noises when compressed. The connection points between the shock absorber and the vehicle body usually have buffer rubber. This buffer rubber not only protects the vehicle body but also enhances driving comfort. Various components of the car's chassis are typically connected with rubber bushings. Once these bushings age, they can affect the vehicle's handling, so it is essential to replace them promptly when they deteriorate.
As someone who's been working with cars for years, I often hear a clunking noise from the front wheels on rough roads, which is mostly due to suspension issues. For example, worn or loose ball joints or control arm bushings can cause rattling sounds when driving over bumps. It could also be leaking shock absorbers or aging springs, leading to poor damping and collision noises. Additionally, problems with wheel bearings or hubs can cause instability and abnormal noises. I've dealt with similar situations before and recommend directly inspecting these key components—if you feel increased steering wheel vibration while driving, that's a clear sign. Delaying repairs not only leads to annoying noises but may also affect steering safety and even cause more serious accidents. It's best to have a professional shop check it out with a lift—don't put it off, safety first.
