Abstract: A hitch pin assembly includes a hitch pin, housing and shoulder bushing. The housing removably connects to the bushing when the bushing is seated in the aperture of a receiver tube. When the housing is so connected a plunger of the housing extends through the bushing and projects into the receiver tube. When the shank is inserted into the receiver tube the plunger tip catches the aperture of the shank, holding the shank in a position in which the pin-receiving apertures on the receiver tube and shank are aligned. The hitch pin is then inserted from one side of the receiver tube and into the bushing. A plunger in the housing translates along a projection in a track of the plunger to reveal the projection to the hitch pin tip and place it into position for engagement with the inserted hitch pin. The engagement holds the shank and eliminates rattling.
