Which of the following components is NOT part of a power steering assembly?

The correct choice, which identifies a component that is not part of a power steering assembly, is the leaf clip. In the context of power steering systems, key components include the power steering pump, steering gear, and fluid reservoir.

The power steering pump is essential because it generates hydraulic pressure needed to assist in steering, reducing the effort required by the driver. The steering gear translates the rotational motion of the steering wheel into the directional movement of the wheels. The fluid reservoir holds the hydraulic fluid that is essential for the operation of the power steering system, ensuring that there is a sufficient supply to allow the system to function correctly.

In contrast, a leaf clip is typically associated with the attachment of leaves or components in a leaf spring suspension system and has no role in the functioning or assembly of a power steering system. Thus, identifying the leaf clip as not belonging in this context reflects an understanding of the specific components necessary for power steering functionality.
