What This Product Does

The bearing supports the rear hub as the wheel turns, carrying loads through the wheel assembly while limiting rotational friction.

Functions

  • Allows the rear hub to rotate.
  • Carries vertical and lateral wheel loads.
  • Controls unwanted movement within the hub assembly

Technical Details

  • Brand: OE Match.
  • Reference: 99905305502.
  • Installation position: Rear.
  • Construction type: angular-contact bearing.

Symptoms of Fault

  • A hum or drone whose pitch varies with vehicle speed.
  • Bearing noise that changes during cornering.
  • Noticeable play when the wheel is rocked.
  • Vibration or uneven tyre wear.

These symptoms can have other causes, so inspect the hub and surrounding components before replacing the bearing.

Why Replacement Matters

A worn bearing can develop noise and excessive movement. Replacing a confirmed faulty bearing addresses wear within the hub assembly; inspect adjoining components for damage at the same time.

Fitting Advice

Please Note - It is recommended to replace the hub nut as this is a use once only item.

FAQs

Must both rear bearings be renewed together?
Not necessarily. Inspect both sides and base the decision on their condition, age and mileage.

How can the noisy side be identified?
Cornering can alter bearing noise, but workshop inspection should confirm which bearing requires replacement.

About Wheel Bearings & Kits

Porsche Wheel Bearings & Kits | Design911 Suspension Components for Smooth Rotation, Precision & Safety

Wheel bearings are critical components within your Porsche’s suspension and axle assembly, ensuring smooth, friction-free rotation of the wheels. They support the vehicle’s weight while allowing the wheels to spin precisely and quietly at high speeds. Properly functioning bearings contribute to stability, ride comfort, and predictable handling — all essential for maintaining the performance and safety your Porsche is known for.

At Design911, we supply a complete selection of wheel bearings and bearing kits, engineered for precision fitment, strength, and longevity. Each bearing set is crafted from premium-grade materials and designed to meet the high-performance demands of both classic and modern Porsche models. Whether for routine maintenance, performance upgrades, or full restoration, our range ensures your Porsche delivers a quiet, stable, and confident ride.

What Do Wheel Bearings Do?

Wheel bearings enable the wheels to rotate smoothly around the hub while supporting vertical and lateral loads.

Core Functions:
• Allow free and precise wheel rotation with minimal friction.
• Support vehicle weight while maintaining wheel alignment.
• Reduce vibration, noise, and rolling resistance.
• Enhance cornering stability and braking performance.
• Protect suspension and hub components from excessive wear.

High-quality bearings ensure quiet operation and smooth performance, providing the secure, agile driving dynamics that Porsche drivers demand.

Why Do Wheel Bearings Fail or Degrade?

Wheel bearings operate under high load, temperature, and rotational stress — eventually leading to wear or damage.

Common Causes of Failure Include:
• Contamination from water, dirt, or road debris.
• Loss of lubrication or grease degradation.
• Corrosion or pitting of the bearing races.
• Impact damage from potholes or kerbs.
• Wear due to age or improper installation torque.

When wheel bearings fail, symptoms can include humming noises, vibration, wheel play, or uneven tyre wear — all of which reduce handling precision and driving safety.

Why Replace or Upgrade Your Porsche Wheel Bearings?

Replacing worn wheel bearings restores smooth, quiet operation and ensures stable, predictable handling. Upgraded bearing kits offer increased durability for high-performance or track-driven vehicles.

Key Benefits:
• Eliminates vibration, wheel play, and noise.
• Restores precise steering and suspension stability.
• Improves safety, grip, and cornering confidence.
• Available as complete front or rear bearing kits for Porsche models.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Cayenne, Panamera, and Macan.
• Ideal for maintenance, restorations, or high-performance upgrades.

Design911’s Porsche wheel bearings and kits are engineered for accuracy, durability, and performance — ensuring your Porsche runs as smooth and stable as the day it left the assembly line.

Highlights

• Premium Porsche wheel bearings and complete bearing kits.
• Precision-engineered for quiet, friction-free rotation.
• Restores handling, steering accuracy, and ride comfort.
• Manufactured from high-strength, wear-resistant materials.
• Suitable for both classic and modern Porsche models.
