What causes the abnormal noise in GLC on bumpy roads?

[Frieda]

Here are the specific reasons for the abnormal noise when the GLC drives on bumpy roads: 1. Check the car's shock absorbers. It's best to go to a 4S shop or repair shop and use a lift to raise the vehicle to inspect whether there are gaps in the shock absorbers or faults in the suspension. If the shock absorber is leaking oil, it may be due to a faulty oil seal gasket, and the shock absorber needs to be replaced. Generally, the service life of shock absorbers is 80,000 to 100,000 kilometers. When the car has driven 80,000 kilometers, you can ask the technician to pay attention to the condition of the shock absorbers during regular maintenance. If there is a fault, repair it in time. 2. Excessive gap in the steering tie rod ball joint may also cause abnormal noise when turning. In severe cases, there may be steering wheel shaking or tire wear, and the ball joint should be replaced at a 4S shop or repair shop promptly. 3. Excessive gap or looseness in the 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 at a 4S shop or repair shop promptly.
