Why does the front of the car chassis make a clunking noise when driving on bad roads?

The reasons why the front of the car chassis makes a clunking noise when driving on bad roads: 1. First, check the car's shock absorbers. Based on the location of the sound, determine which part is affected. When the car is parked on flat ground, the distance between the car and the ground is too small, making it difficult to inspect the fault. It is best to go to a repair shop and use a lift to raise the vehicle to check if there are any gaps in the shock absorbers or if there is a fault in the suspension. 2. Excessive gap in the steering tie rod ball joint. Apart from making a clunking noise on bumpy roads, there may also be abnormal noises when turning. In severe cases, the steering wheel may shake, or the tires may wear unevenly. The ball joint should be replaced promptly at a 4S shop or repair shop. 3. Excessive gap in the lower control arm or loose lower control arm. The lower control arm is an important component that maintains the elasticity of the car body and is part of the car's suspension. The lower control arm connects the axle and the frame, buffering the impact of bumpy roads on the car. Once the lower control arm fails, it should be replaced promptly at a 4S shop or repair shop.
If the chassis rattles on rough roads, it's most likely due to loose suspension components. Having driven for ten years, I've encountered this issue frequently. The most common causes are leaking or failed shock absorbers, which lack sufficient damping on bumpy roads, leading to parts colliding. Another possibility is worn or loose ball joints or bushings in the control arms, causing clunking sounds over potholes. Additionally, loose stabilizer links or lower arm bolts are common culprits, creating rattling noises when hitting bumps. For inspection, park on level ground and shake the wheels or visually check chassis connection points. Addressing this promptly is crucial, as neglect can accelerate tire wear or even cause steering instability. It's best to visit a repair shop and have it checked on a lift. Don't underestimate these noises—they can significantly reduce driving comfort.
