Wheel Carrier Bush 65 Shore Rating, Rear.
Restore rear suspension precision with this wheel carrier bush for the Porsche 997 (2005-10, Carrera MKI & MKII, Coupé/Targa/Cabrio). With a hardness of 65 Shore, this bush provides the ideal fusion of compliance and firmness — helping to maintain correct carrier alignment, reduce rear noise/vibration, and preserve tyre wear. Whether you’re renewing worn components or refreshing the rear chassis mounts, this bush ensures the wheel carrier mount behaves exactly as intended.

What This Product Does:

• In the rear suspension of the 997, the wheel carrier/hub assembly is mounted to the suspension linkages / knuckle, and the bush or bushing at the mounting point provides isolation and alignment.
• The wheel carrier bush acts as the mounting interface, helping absorb road shocks, reduce noise/vibration, and maintain correct geometry of the wheel carrier relative to the vehicle’s chassis/subframe.
• With a correct hardness (65 Shore in this case), the bush gives the proper balance between compliant behaviour (for comfort and longevity) and firmness (for alignment stability and handling precision).
• Replacing a degraded bush ensures the wheel carrier remains correctly located and aligned, avoiding excess movement under load which can degrade handling, alignment, or tyre wear.

Symptoms & Signs Of Wear/Need For Replacement:

• Clunking or knocking noises from the rear when going over bumps, especially from the area of the wheel carrier/hub.
  
• Rear instability or vague handling: the rear may feel loose, or alignment may shift unexpectedly under load (cornering, acceleration, braking).
  
• Uneven or accelerated tyre wear on the rear wheels — particularly inner or outer edge wear — due to geometry shift caused by excessive carrier movement.
  
• Vibration or poor noise/vibration/harshness levels at the rear, especially after installation of new tyres, alignment, or suspension components.
  
• Visible deterioration of the bushing: cracks, splits, collapse, or the rubber is soft/loopy when compared to new; or the bushing may be loose in its housing/unseated.
  
  

Why Replacement / Upgrade Matters:

• Replacing worn wheel carrier bushes helps restore the correct behaviour of the rear suspension: the carrier remains securely located, alignment remains stable, and the car handles as it should.
  
• Because the 65 Shore rating matches the OEM street compound, you maintain the intended balance between comfort and performance. If the bushing is too soft (worn or degraded), you lose alignment stability; if one upgrades to a much stiffer bush without considering other suspension components, you may introduce unwanted harshness.
• For owners of the 997 especially with upgraded suspension, stronger tyres, or high-performance use, making sure the wheel carrier bushes are in good condition is foundational — worn bushes can compromise the benefit of other suspension upgrades.
• Good bushing condition contributes to longer tyre life, better alignment retention, reduced rear suspension noise, and more confident handling under all conditions.
  
• For a car of that age (2005-10 era), rubber parts will naturally age, degrade, and a proactive replacement is good maintenance rather than waiting for failure.

What This Product Does:

• The wheel carrier bush is installed at the interface between the wheel carrier / hub carrier assembly and the vehicle’s rear suspension or subframe mount. Its role is to control movement, absorb some vibrations/loads, and provide a stable mounting point for the carrier.
• By using a stiffer compound (85 Shore vs standard 65 Shore), the mount allows less compliance, meaning the wheel carrier remains more tightly located under loads (cornering, acceleration, braking), which in turn helps maintain alignment (camber, toe, etc.) and improves handling precision.
• In effect: it helps keep the rear wheels more accurately positioned relative to the chassis during dynamic driving rather than letting the carrier mount deflect under load, which can degrade handling or tyre wear.

Symptoms & Signs Of Wear Or Need For Upgrade:

• Clunks, knocks or banging noises from the rear suspension or wheel carrier area, especially when going over bumps or during heavy cornering.
  
• Rear-end instability or vague handling, such as the rear stepping out, feeling loose or less composed when pushed hard.
  
• Uneven or accelerated tyre wear on the rear tyres, especially on the shoulder or edge, due to alignment shifting under load.
  
• Suspension modifications: If the car has been lowered, fitted with stiffer springs/anti-roll bars, or used in performance/track settings, the standard 65 Shore bush may be too soft — you might see more deflection than ideal. The 85 Shore version offers firmer control.
  
• Visible deterioration of the original bush: cracked or collapsing rubber, looseness of the bush in its bracket, or excessive movement of the carrier when tested.
  
  

Why Replacement / Upgrade Matters:

• Upgrading to the 85 Shore version helps restore or improve rear suspension precision, especially for performance or track-oriented driving.
  
• It reduces unwanted movement of the wheel carrier under dynamic loads, which results in better alignment retention, sharper handling, and longer tyre life.
  
• For vehicles still using the softer 65 Shore bushing, if they are used aggressively or have upgraded suspension components, the softer bush might compromise handling by allowing too much flex; hence the firmer 85 Shore version is a smart step.
• It supports the rest of your suspension upgrades: if you’ve improved springs, bushings, sway bars etc., using a firmer bush at the carrier mount ensures nothing is held back by a soft mounting point.
• Even for road use, replacing worn bushes prevents drift in alignment settings, reduces rear-end noise/vibration, and helps maintain the driving experience.

What This Product Does:

• The bolt helps maintain the alignment and secure mounting of the hub assembly, ensuring the wheel and bearing remain solidly held to the vehicle’s suspension / wheel carrier.

Symptoms Of Failure / Needs Replacement:

• Loose hub assembly or play at the wheel bearing / hub interface
  
• Noise (rattling, knocking) from the wheel / suspension area
  
• Abnormal wheel alignment / geometry or uneven tire wear
  
• Bearing / hub damage, because the hub may move relative to its mounting surface under load
  
• Potential safety hazard if the wheel or hub becomes unstable

Why Replacement Matters:

• Safety-critical component: Keeps the wheel hub and bearing securely attached to the suspension carrier.
  
• Prevents looseness and wheel wobble: Ensures stability under braking and cornering.
  
• Essential during service: Always replaced when removing the hub or bearing for correct torque retention and clamping force.
