Information On Component Assessment

WARNING: This page is about a different car, the 2024 Porsche 911, 2023 Porsche 911, and 2022 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

The following illustrations compare central wheel lock components (wheel hub, wheel adapters, wheel and brake disc) as they normally look on vehicles that have been driven with components that show signs of excessive wear.

The following applies to the wheel hub: The wheel hub must always be replaced if the central bolt has a torque of > Loosening torque less than 400 Nm (296 ftlb.) or if the driving pins can be turned by hand. It really doesn't matter how the wheel hub looks in this case.

Prerequisite: The central bolt was originally tightened to the prescribed tightening torque and the vehicle has since been driven.

The following also applies: If the vehicle that is being checked shows at least one sign of wear as shown, the affected component and any other components must be replaced as required in accordance with the relevant instructions.
