Thank goodness I found this one before I spent a bunch of money having the rearend worked on. When getting up or down on the throttle, it would sometimes make a sharp bang in the rear end. It took me a while to realize that it only did it while towing. It came down to an oversized pin hole in the receiver hitch. It was always rattling so I put on one of those bolt-on anti-rattle things. It totally eliminated the rattle. However, when using the throttle hard, it allowed the ball mount to jump back and forth 1/8" under the antirattle thing. It's amazing how much noise that can make. I fixed it with some small nails. I cut them down to 1/4" and stuck them in the holes beside the pin. I replaced the pin with a grade 8 bolt and nut to keep them in place. I'll just have to carry 2 15/16" wrenches if I ever need to take it off.
