We recently talked about an annoying phenomenon that travel trailer RVers sometimes face: hitch clunk . Slop in the hitch system allows the trailer a bit of room to move on the hitch, and as you pull forward from a stop you may hear a “clunk!” and perhaps another when stopping. Long-time RVer Dave Helgeson offered a suggestion on resolving this nettlesome noise . Well, as everyone declares, there’s more than one way to quiet a clunk. Reader Mel G. weighs in with a solution of his own, one that he feels might even be a simpler fix.
When Mel’s hitch became a problem child , he whipped out a feeler gauge and took a measurement of the space between the hitch “stinger” and the receiver. He discovered there was .064″ of space for both side play and top-to-bottom play. His solution?
“I made two .060 shims from steel strapping, drilled a pin hole in one, and use them to stop the slop. Notice also in the photo that there is a .040 shim between the head and the ‘clevis’. This is due to the fact that there is play between those two, and cranking up the bolts will not close the gap.”
Still, Mel had a concern. He determined that the gap could close, resulting from a loosening up of mounting bolts — which could be a serious safety issue: a fatiguing of the bolts. To handle this eventuality, Mel replaced the bolts. “In lieu of the Grade 5 […]
