What Causes the Clunking Sound When a Car Goes Over Speed Bumps?

[VonJulianna]

Causes of clunking sound when a car goes over speed bumps: 1. Excessive clearance at the front fixing point of the steering knuckle. It's necessary to first inspect the bushings of the stabilizer bar links and ball joints, and check if there are any issues with the suspension ball joints. Excessive clearance can affect the rotation of the bearings and requires timely repair; 2. Problems with the car's shock absorbers, caused by insufficient damping fluid in the shock absorbers. It is recommended to replace the shock absorbers directly; 3. Excessive clearance in the tie rod ends of the steering gear, which requires professional assessment. It's advisable to have it inspected at a professional repair shop or a 4S shop. When driving over speed bumps, always slow down in advance to reduce the car's speed. This not only minimizes scraping but also protects the car's suspension.
