Reasons for abnormal sound of a hub:
1. Suspension system: including loose part, loose wheel hub screw, poor lubrication, rubber bushing damage or fatigue damage, and poor shock absorber function.
2. Axle system: including loose component, worn ball joint, poor lubrication, bent or cracked drive shaft, and worn wheel bearing.
How to prevent hub screws from loosening
1. Before starting a trip, especially on freeways, always remember to inspect normal tyre pressure. Check if the tyres have been seriously worn and if the hub screws have loosened.
2. During a trip, refrain from listening to the radio or playing music for long, as this may distract you and prevent you from concentrating on driving. As the driver, you should closely follow the conditions of the car all the time, and watch out for any abnormal sound.
