• play in the steering wheel affecting driving comfort and safety.

A used original component is often a favorable compromise between the cost of repair and maintaining the proper operating parameters of the steering system, especially in vehicles that are used intensively or have higher mileage.

• restoring factory handling parameters,
• correct wheel alignment after replacement,
• consistent operation with other steering system components.

Due to its importance for safety, installation should be entrusted to a specialized service, and professional wheel alignment should be performed after replacement.
