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.
