A pin joint including a pin having opposite stepped axial ends and an outer surface extending therebetween, the pin being adapted to be supported for pivotal movement in a bearing of a first member such as a lift arm or the like with the opposite stepped axial ends in predetermined axially spaced relation to axial end faces of the bearing. A pair of annular retainers are adapted to be positioned in apertures of brackets or other elements of a second member such as a bucket or other implement and have inner circumferential stepped surfaces defining cavities adapted for cooperatively receiving and engaging the stepped axial ends of the pin, respectively, for positioning the retainers and the pin in predetermined axial relation to the bearing. The present joint further includes a pair of collets adapted to be wedged in the apertures of the brackets between the inner side walls and the retainers, respectively, for holding the retainers and the pin in position without affecting the predetermined axial relationship thereof to the bearing.
