I have a Reese Signature Series sliding hitch installed in my short bed Ford. My hitch is removable and leaves four holes in the bed. My hitch has been silent for 6 towing seasons and just this month started making a banging noise at acceleration and braking. I narrowed the movement down to play between the tubular rails and the rollers. The pucks hold firm to the bed, but I can lift the hitch off the tubes ever so slightly. I'm not sure how to take up the slack to make my hitch quiet again.
