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.
