A floating pin joint assembly pivotally connects a lift arm between spaced frame members. The lift arm includes a bushing with bearing surfaces supported on the pin for relative movement. Extending end portions of the pin are supported on bearing surfaces defined by collars connected to the frame members by inserts press fit into the frame members. Removable cover plates connected to the inserts contain the axial movement of the pin and permit removal of the pin and other components from the assembly. The load bearing surfaces are disposed within a lubricated chamber extending between the cover plates.
