Key Point: Strut Mount and Shock Bearing are two different components. Although both are located at the top of the strut, they serve different functions. The strut mount connects and cushions, while the bearing rotates. They are usually replaced as an assembly.
1. Positional Relationship
In the front suspension system, the strut is vertically installed between the wheel and the body. At the very top of the strut, you will find two important components:
- Strut Mount: Located at the top, directly contacting the vehicle body
- Strut Bearing: Located inside or below the strut mount
2. Functions of Strut Mount
The strut mount is a rubber-metal composite part that mainly performs the following functions:
- Connection: Secures the strut to the vehicle body tower position
- Cushioning: Rubber part absorbs road vibrations
- Positioning: Maintains correct installation angle and position
3. Functions of Strut Bearing
The strut bearing is a precision rolling bearing with the core function of allowing the strut to rotate smoothly when steering.
