Purpose and function in the steering system

The sleeve cover in the steering column is responsible for the proper guidance of the column shaft and for separating moving parts from dust, moisture, and small debris. In practice, this translates into:

• smoother operation of the steering mechanism,
• reduction of excessive play in the column,
• reduction of noise and vibrations transmitted to the steering wheel,
• extended service life of the cooperating column components.

In Mercedes W163 models, a properly selected sleeve cover is essential for safety and driving comfort, as it stabilizes a critical section of the steering system.

Set characteristics and fitment

The presented sleeve cover set has been designed specifically for the steering column construction in the W163 series, ensuring proper geometry and compatibility with the factory system. Using an original solution allows you to maintain:

• correct positioning of the sleeve relative to the column shaft,
• stable mounting without the need for modifications,
• consistency with other steering system components.

As a result, the installation process is predictable, and after replacement, you can achieve consistent operation of the system in line with factory specifications.

Condition, inspection, and practical application

The item comes from the Steering columns category and is offered as a used part, which is a cost-effective solution for users looking for an economical yet structurally compatible alternative to new components. Before reusing this type of element, it is recommended to:

• verify the working surfaces for cracks and excessive wear,
• check the stability of the mounts and sleeve support points,
• inspect the interaction with the column shaft after installation (no binding, no excessive play).

A properly selected and installed sleeve cover helps maintain predictable vehicle behavior during maneuvering and reduces the need for frequent service interventions within the steering column.
