Over the past months from time to time I always see where someone asks about loose ball mounts in the receiver hitch. It has been posted a time or two, but I thought I would put in here my solution. If you have this problem, try this solution. It doesn't take long and just a few simple tools. Crawl under the receiver hitch, or better yet put it on a lift; most muffler shops will for a very small fee; and drill a hole in the center bottom of the hitch just under 3/8 in diameter. Next, tap the hole to accept a 3/8 bolt. Make sure when you tap that you go in straight. Put in the ball mount after all is complete and simply screw in a 3/8 bolt. I used a 1 inch length 3/8 stainless bolt and looks cool too. Tighten up snug and clanking and rattling are over. You may also want to put a jam nut on the bolt to possibly prevent backing out. I did not on mine and it holds fine........Just thought that this may help out several of you BBC guys out there that have the rattles..
