  Required Quantity
  

Two spacers are required per car. Sold individually.

What Is This Part?

This spacer ring sits on the front wheel spindle behind the inner wheel bearing. It belongs to the hub and bearing installation carried by the front suspension strut. As well as establishing the bearing's seating position, its outer surface provides a running surface for the hub seal. Its condition is therefore relevant when inspecting the bearings, renewing a leaking hub seal or rebuilding the front hub assembly.

What Does This Part Do?

• Positions the inner bearing: Provides the spacer interface behind the inner wheel bearing on the spindle.
• Supports the hub seal: Provides the surface against which the seal lip runs as the hub rotates.
• Completes the hub installation: Works with the spindle, bearing and seal as part of the front wheel hub arrangement.
  
  Why Replace This Part?

Replacement may be needed if inspection reveals a worn groove, corrosion, scoring or damage on the seal-running surface. An uneven surface can prevent the seal lip from making consistent contact, so fitting a new seal alone may not resolve leakage. Damage to the spacer's seating surfaces also needs attention before the hub is reassembled.

Inspect the ring during front bearing or hub-seal work, particularly if the assembly has suffered contamination, overheating or difficult dismantling. A serviceable spacer does not need replacing simply because the bearings are being renewed. Wheel noise or play should prompt inspection of the complete hub assembly rather than an assumption that this ring is at fault.

When to Replace This Part?

• Grooved seal surface: A visible wear track is found where the hub seal contacts the ring.
• Corrosion or pitting: Surface deterioration affects the seal contact area or bearing seating face.
• Removal damage: The ring has cracks, distortion, burrs or damaged edges after dismantling.
• Poor seating: Inspection confirms that damage prevents the ring or inner bearing from seating correctly.
• Persistent leakage: A hub-seal leak is traced to a damaged running surface on the spacer.
  
  Where Is This Part Fitted?

Location: On the front wheel spindle at the inner end of the hub, behind the inner wheel bearing and within the hub-seal area.

FAQs

• Will replacing this spacer cure wheel bearing noise? Not necessarily. Noise can come from the bearings or other components. Check bearing condition, adjustment, lubrication and the spindle before deciding which parts need replacement.
• Should it be inspected when replacing the hub seal? Yes. Check the seal-running surface for grooves, corrosion and damage, since a new seal needs a suitable contact surface.
• Does a new spacer set the bearing adjustment? No. The hub must still be assembled and the wheel bearings adjusted using the correct procedure for the vehicle.

Diagram Ref No 7

Constructed from high-quality hardened steel with precision-machined bearing races and rolling elements, the rear wheel bearing is designed to withstand the substantial radial and axial loads generated during acceleration, braking and cornering. It provides accurate wheel alignment and smooth rotation while helping to minimise friction and wear throughout the rear suspension and drivetrain system.  

What This Product Does:

• Supports the rear wheel hub assembly.
• Allows smooth and efficient wheel rotation.
• Reduces friction between moving wheel components.
• Maintains correct wheel alignment and positioning.
• Supports vehicle stability during cornering and braking.
• Helps ensure precise handling characteristics.
• Carries radial and axial loads generated during driving.
• Contributes to safe and reliable vehicle operation.

Symptoms Of Wear Or Failure:

• Humming, rumbling or growling noises from the rear wheel area.
• Noise that increases with vehicle speed.
• Excessive wheel play or looseness.
• Vibration felt through the vehicle.
• Uneven tyre wear.
• Reduced handling stability.
• Wheel hub overheating.
• ABS warning lights in some applications where the bearing incorporates a sensor ring.
• Rough wheel rotation during inspection.
• Severe bearing failure causing wheel instability.

Why Replacement Matters:

• Rear wheel bearings are subjected to constant rotational loads, road impacts, moisture, dirt and temperature fluctuations throughout their service life. Over time, bearing surfaces can wear, lubrication can degrade and contamination may enter the bearing assembly, reducing performance and reliability.
• A worn wheel bearing can compromise vehicle handling, generate excessive noise and place additional stress on the wheel hub, suspension and braking components. If left unresolved, severe bearing wear may result in wheel misalignment, damage to surrounding components or, in extreme cases, loss of wheel support.
• Replacing a worn rear wheel bearing restores smooth wheel operation, improves vehicle stability and helps maintain safe driving characteristics. An OE Match replacement provides factory-style fitment, precision manufacturing and long-term durability, ensuring reliable performance and preserving the handling and safety standards expected from your Porsche.
