Function & Application

The crossbar pivot pin serves as the primary hinge point between the underlift/stinger boom and the crossbar head (T-bar). Over time, constant articulation, heavy loads, and road vibration cause wear on the pin and bronze bushings. Rebuilding the joint using SKU 124004106 restores proper tolerance, eliminates excessive slop or play in the wheel lift assembly, and ensures safe towing operations under heavy loads.
