The c-lock must be removed prior to which action?

The c-lock is a critical component in the assembly of certain drivetrain systems, particularly in the context of axle and pinion shaft assemblies. Its primary function is to secure components in place, ensuring that parts such as the pinion shaft and axle shaft do not come loose during operation.

Removing the c-lock is essential prior to taking out either the pinion shaft or the axle shaft because it provides the necessary restraint that holds these components. If the c-lock is not removed, attempting to remove either the pinion or axle shafts could lead to damage or misalignment, as the c-lock would still be holding those components in place.

In summary, the correct answer indicates that the removal of the c-lock is necessary before performing either action, which ensures safe and proper disassembly of these critical drivetrain components.
