How much does it cost to change a Mercedes wheel hub?

The price of Mercedes-Benz CLA wheel hub is around 3500 yuan. Wheel hub, English name: Car Rim, is a cylindrical metal part centered on the shaft and used to support the tire. Generally speaking, the axle is installed in the center of the wheel, which is an important part connecting the brake drum (brake disc), wheel disc and half shaft.

The main advantages of steel wheel hub are simple manufacturing process (generally casting process, for example, aluminum alloy wheel hub is generally produced by low-pressure casting process), relatively low cost and strong metal fatigue resistance, which is also commonly known as cheap and good quality. However, the disadvantages of steel wheel hub are more prominent, such as ugly appearance (it can be said that there is no appearance at all), heavy weight (the same wheel hub steel material is much heavier than aluminum alloy material), large inertial resistance, poor heat dissipation and easy rusting.

Alloy wheels can just make up for this problem. It has the advantages of light weight, low inertia resistance, high manufacturing accuracy, small deformation and low inertia resistance during high-speed rotation, which is beneficial to improve the straight-line driving performance of the automobile and reduce the rolling resistance of the tire, thus reducing fuel consumption. The thermal conductivity of alloy material is about three times that of steel, which has good heat dissipation and can play a certain role in the thermal attenuation of vehicle braking system, tire and braking system. The alloy wheel hub of the original car in the market is mainly aluminum alloy. Of course, in order to meet some special requirements and improve vision, many modified wheels will choose elements such as chromium and titanium as basic materials. However, compared with steel wheels, alloy wheels are much more expensive, so often in many low-end original cars, steel wheels will appear on low-profile models, while alloy wheels are standard on high-profile models.
