The kit includes a high-quality rear wheel bearing together with the associated installation hardware and service components, providing a convenient all-in-one solution for repairs or preventative maintenance. Manufactured from premium-grade hardened bearing steel with precision-ground rolling elements and durable seals, the bearing is engineered to withstand heavy radial and axial loads while providing smooth, low-friction wheel rotation and long service life.

What This Product Does:

Supports smooth rotation of the rear wheel hub.
Maintains accurate wheel alignment and hub stability.
Reduces friction between the wheel hub and axle assembly.
Supports safe handling and vehicle stability.
Minimises drivetrain and road noise.
Includes the essential components required for a complete wheel bearing replacement.
Helps ensure long-lasting bearing performance.
Forms an essential part of the rear suspension and wheel hub assembly.

Symptoms Of Wear Or Failure:

Humming, droning or grinding noise from the rear of the vehicle.
Noise increasing with road speed.
Excessive play in the rear wheel.
Vibration through the vehicle.
Rough wheel rotation when inspected.
Uneven tyre wear.
ABS warning light if bearing movement affects the wheel speed sensor.
Excessive heat around the wheel hub.
Reduced handling stability.
Bearing noise becoming louder when cornering.

Why Replacement Matters:

Rear wheel bearings operate under constant load while supporting the weight of the vehicle and enduring braking, cornering and acceleration forces. Over time, contamination, moisture, impact damage and normal wear can degrade the bearing surfaces, leading to increased friction, noise and excessive wheel movement.
A worn wheel bearing can negatively affect handling, braking performance and tyre wear. If left unresolved, bearing failure can damage the wheel hub, axle and suspension components and, in severe cases, compromise wheel retention and vehicle safety.
Replacing the complete wheel bearing assembly using a comprehensive kit ensures all essential service components are renewed at the same time. The OE Match Rear Wheel Bearing Kit provides factory-style fitment, precision-engineered components and long-lasting durability, helping restore quiet operation, safe handling and the reliable driving performance expected from your Porsche.

Diagram ref no 9

The outer wheel bearing supports the rear wheel hub / axle assembly and allows the wheel to rotate smoothly under load. It helps maintain correct wheel alignment, supports vehicle weight at the rear axle, and reduces friction between rotating and fixed suspension components.

Functions
•  Supports the rear wheel hub / axle assembly
•  Allows smooth rear wheel rotation
•  Helps maintain correct rear axle alignment and stability
•  Supports vehicle load through the rear wheel bearing assembly
•  Reduces friction and wear between rotating components
•  Replaces worn, noisy, loose, or damaged original wheel bearings
•  OE Match replacement for rear axle service and restoration.

Why Replace This Part?
Wheel bearings are exposed to road load, heat, vibration, grease, moisture, and long-term rotation. Over time, the bearing can wear, pit, loosen, seize, or become noisy. A worn rear wheel bearing may cause humming, rumbling, grinding, wheel play, vibration, uneven tyre wear, or unsafe rear axle movement. Replacing the bearing helps restore smooth wheel rotation and safe rear suspension operation.

When to Replace This Part
•   Humming, rumbling, or grinding noise is heard from the rear wheel area
•   Wheel play or looseness is found during inspection
•   The bearing feels rough, dry, seized, or worn
•   Grease leakage or contamination is present around the bearing area
•   The rear hub, axle, or suspension is being serviced
•   The vehicle has failed inspection due to wheel bearing play
•   The car is undergoing Porsche 911 rear axle restoration
