This part, known as the rear wheel hub assembly , is a crucial mechanical component mounted on the rear suspension arm of the JAC GS3 . Its primary function is to secure the rear wheel to the chassis and provide the surface on which the brake disc is mounted. Crucially, the hub contains an internal bearing that allows the wheel to rotate smoothly with minimal friction, and it often houses the anti-lock braking system (ABS) sensor .
If you hear a buzzing or whining sound that increases with the speed of the car (especially when exceeding 40 km/h), or you feel a shudder and vibration in the car, or you notice that the rear wheel has become abnormally free to move, these are common signs of damage to the flange bearing and the need for immediate replacement to ensure safety.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
