Abstract
A pin joint assembly for pivotally connecting a plurality of components, the assembly including a joint pin with a channel at one end disposed transverse to a longitudinal axis of the pin and a first retainer disposed in the slot that extends beyond a circumference of the pin to restrict axial movement in a first direction, while a second retainer is positioned over the first retainer to restrict axial movement in the opposite axial direction, a retainer base having a slot being configured to receive one end of the first retainer to restrict rotational movement of the first retainer and attached joint pin. The joint pin and pin joint assembly may be provided as part of a suspension assembly for machine axles, the pin joint assemblies providing pivotal connections between an axle assembly, linkage and frame members.
