What This Product Does

The hub provides the rotating mounting interface for the rear wheel and brake disc, working with the wheel bearing within the rear axle assembly. Its studs provide the fixing points for the wheel nuts. This component is a wheel hub, rather than the surrounding trailing arm or wheel carrier.

Functions

• Provides the rear wheel mounting interface.
• Locates the wheel and brake disc relative to the bearing assembly.
• Transfers driving and braking loads through the wheel connection.

Technical Details

• Part reference: 90133106509.
• Position: Rear.
• Supplied with wheel studs.
• The 1970–73 rear axle diagram identifies the application as 911 T/E/S.
• Both supplied diagrams record two hubs per vehicle; this is not a statement of pack contents.
• Bearings and trailing arms are identified as separate components in the supplied diagrams.

Symptoms of Fault

• Wheel movement associated with a worn bearing seating surface.
• Recurring bearing noise where hub wear has been confirmed.
• Vibration or inconsistent braking feel associated with an untrue mounting face.
• Corrosion affecting the bearing fit or mating surfaces.

Why Replacement Matters

A damaged bearing seat or distorted mounting face may require hub renewal rather than bearing replacement alone. Inspect the bearing, studs and adjoining components before deciding which parts need replacing; noise or vibration does not identify the hub as the cause by itself.

FAQs

When should the hub be renewed with the bearing?
When inspection confirms wear or damage at the bearing seat, or distortion of the mounting face.

Is additional fitting hardware required?
Check the vehicle-specific repair instructions for bearings, seals and fasteners required for the work. Do not assume they are included with the hub.

What matters during installation?
Clean the mating surfaces and use suitable pressing and support tools to avoid damaging the hub or bearing.
