What Causes the Metallic Clanging Sound When Driving Over Bumps?

[VonPaul]

It may be caused by the detachment of the rear hydraulic shock absorber's buffer rubber ring, resulting in metal-on-metal contact with the upper shock absorber cup during bumpy conditions. The reasons for abnormal vehicle noises are as follows: Half-shaft issues: Prolonged torsional fatigue and impact forces can cause the vehicle's half-shaft to bend, twist, break, or develop worn/skewed spline teeth. This manifests as rhythmic front-end vibrations accompanied by noises during acceleration within specific speed ranges, which disappear or lessen upon releasing the throttle. Loose engine belt: A slipping belt creates abnormal noises. The resulting friction generates heat that elongates the belt, worsening the slippage and creating a vicious cycle. This condition requires belt adjustment at a repair shop.
