Information on component assessment

The following graphics compare central wheel lock components 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 loosening torque of the relevant central bolt is 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 other components, if necessary, must be replaced in accordance with the relevant instructions.
