What Causes the Whirring Wind Noise When the Car is Running?

[Levi]

The reasons for the whirring wind noise when the car is running are: 1. Wear and looseness in the wheel bearings; 2. Uneven tire wear. The main function of wheel bearings is to bear the weight and provide precise guidance for the rotation of the wheel hub, requiring them to withstand both axial and radial loads. They feature good assembly performance, the ability to omit clearance adjustment, light weight, compact structure, high load capacity, and the characteristic of being pre-lubricated sealed bearings that eliminate the need for external hub seals. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. Typically installed on metal rims, tires support the vehicle body, cushion external shocks, ensure contact with the road surface, and maintain the vehicle's driving performance.
