Abstract
A device for eliminating rattle in a receiver-type hitch due to movement between hitch components includes a collar, an adjustment bolt, a lock nut and a second nut. The collar has a center wall and two side walls forming a U-shaped bracket that can fit over a reinforcing lip of the hitch receiver tube. A front wall on the collar has an opening for receiving a mount shank as it enters the receiver tube. An adjustment bolt extends through the center wall to tighten the collar onto the hitch receiver tube. When the adjustment bolt is tightened, the center wall of the collar moves away upward away from the receiver tube, causing the opening in the front wall to lift the shank against the inner wall of the tube and prevent it from moving within the tube. The lock nut then holds the entire anti-rattle assembly into position. Thus, the anti-rattle device prevents hitch rattling with a minimum of components.
