Diagram Ref No 10.

The rear wheel bearing spacer sleeve maintains proper spacing and alignment between the inner and outer wheel bearings within the rear hub. It ensures that the bearings are correctly positioned, reducing play and wear while supporting smooth, stable wheel rotation and optimum handling.

Function:
• Provides correct spacing for rear wheel bearings
• Ensures accurate bearing preload and hub alignment
• Minimizes bearing wear and drivetrain stress
• Supports smooth rear wheel rotation and handling

The wheel bearing spacer sleeve is a small but critical component in the rear hub assembly. Incorrect spacing can lead to excessive bearing load, vibration, poor handling, and premature wear. Replacing a worn or damaged spacer with an OE Match sleeve restores the correct hub geometry, improving reliability and extending the life of bearings, hubs, and associated suspension components.

When to replace:
•  Excessive play or noise from the rear wheel hub
•   Vibration or uneven wheel rotation at speed
•   Evidence of bearing wear or heat damage
•   During rear axle or wheel bearing service
•   When rebuilding or refreshing suspension and hub assemblies
