Reese R16 Noise

I made shims out of galvanized sheet metal, the kind used in duct work for heating and A/C installations. I cut four pieces 3 inches square, cut a rectangular hole in the middle and put them under each mounting leg, the mounting pin is much tighter but still goes in without much persuasion. Then I cut 4 pieces 4 inches long by two inches wide, turned one end up about 3/4 of an inch at a 90 degree angle and tap them in between the slide roll and slide rail. My hitch is a slider. After doing this I don't hear any noise.....none!!!! If I need to pull the slide rail/roll shims out to use the slider they come out with a little help from a large screw driver. However I have never had to use my slider so this has not been an issue.

Cheap fix for an annoying problem!!!
