Wheel Hub Bearing 31206867088 For BMW F25 F01 750 F10F25

A wheel unit is an integral unit consisting of a hub and bearing on a vehicle. There are some differences in design and function between front and rear hub units:

1. Load carrying capacity: The front hub unit is usually responsible for the steering and braking forces of the vehicle and therefore needs to have a higher load carrying capacity. The rear hub unit is mainly responsible for the driving force and torque of the vehicle, so its load carrying capacity is relatively low.

2. Steering function: Front hub units are usually closely related to the steering system and have a steering function. They are usually equipped with wheel bearings and steering knuckles for steering operation. Rear hub units usually do not have steering capability and are more simplified in design.

3. Driving mode: Front hub units are usually used in conjunction with front-wheel drive or four-wheel drive systems to transfer the vehicle's driving force. Rear hub unit is usually used in conjunction with rear-wheel drive or four-wheel drive system to undertake the vehicle's driving force transmission.

4. Structural design: The structural design of the front hub unit is usually more complex and robust due to the higher loads and steering forces it has to withstand. The rear hub unit is relatively simplified, as its main function is to transmit the driving force.

5. Mounting location: The front hub unit is mounted at the front of the vehicle and is closely connected to the steering and braking systems. The rear hub unit is mounted at the rear of the vehicle and is connected to the drive and suspension systems.

In short, the front and rear hub unit in the load bearing capacity, steering function, drive mode, structural design and installation location, there are some differences. These differences are designed to accommodate the different needs and functions of the vehicle to provide better performance and handling.
