How do mechanics replace wheel bearings?

The complexity of wheel bearing replacement varies greatly depending on the vehicle make, model, year, the wheel position (front versus rear), and the drive type (AWD versus FWD):

• 在带有统一轮轴承/轮毂组件的车辆上，卸下制动转子和卡尺。
• 卸下大轴螺母，将轴向后通过统一轮毂组件的中心向后推，并将将轮毂组件固定到转向指关节的三个（或更多）螺栓被移除。
• 然后将轮毂组件从指关节中取出。在将新轮毂组件安装到指关节上时，将螺栓扭转为工厂规格。在许多情况下，需要丢弃旧的轴螺母并用新的螺母替换。必须特别注意将轴螺母拧紧到确切的工厂规格，因为触摸或不足会损害新安装的轴承。所有机电万博体育入口专业人员都在这些关键紧固件上使用校准的扭矩扳手。
• Finally, the brake rotor and brake caliper are re-attached, the wheel installed and the car is road tested.
• On vehicles where the wheel bearing is pressed into a cavity within the steering knuckle, the steering knuckle must be removed from the vehicle in order to press out the old bearing and press in the new bearing.
• On some vehicles, the wheel bearing is pressed onto an axle shaft and thus the axle must be extracted from the axle carrier. This will apply to certain trucks.
