What does a puller designed to remove a pitman arm do?

The correct answer focuses on the function of the puller, which is specifically engineered to facilitate the removal of a pitman arm from the steering gear or the center link. When removing a pitman arm, the puller employs a clamping mechanism that grips the arm firmly and then pulls it off the shaft as a unit. This process uses mechanical leverage to safely and effectively dislodge the pitman arm without causing damage to surrounding components.

In contrast, options that refer to separating a joint, aligning the steering gear, or adjusting steering alignment describe processes that are not directly performed by the puller. While separating a joint may occur as a secondary effect of removing the arm, it does not encompass the primary purpose of the puller itself. Aligning the steering gear and adjusting steering alignment pertain to adjustments and calibrations that occur after the removal and installation of components, rather than the act of removing the pitman arm.
