Loose Reese 16K 5ver Hitch
After having the slider hitch replaced with a fixed hitch, which incidentally removed about 90% of the noise when stopping/starting, there was still a little movement in the hitch and noise. Upon investigation, found that the 4 mounting holes in the bed rails are 9/16" dia for a 1/2" pin. Not wanting to try to find 9/16" pins or fabricate them or drill them out to 5/8" to use a standard hitch pin, I discovered there was about 0.075" clearance between the legs of the hitch and the bed rails. I fabricated (4) 0.060" thick steel plates 2.25" x 4.25" with a 1/2" x 1-1/2" slot to put under each leg and re-installed the (4) pins that come with the hitch. The pins now fit real snug and the hitch doesn't move and all the noise from stopping/starting is eliminated. Now, DW is very happy, which was the whole point of task.
