I had my second Ram Ball mount fail on me today, and wish to share some advice on the use of these. Yakattack replaced my first one, and I appreciate that. I won't ask for a replacement for the second, as I think overall , I was over tightening them, and not lubricating the threads. I wasn't using vise grips to tighten them, but with the rod holder on the ball, using that to snug it a quarter turn or so may have put too much stress on the insert in the ball. In the future I will use a light weight grease on the threads, and make sure they are snug, but not over torqued on the tracks. For those who have these on their boats, check them and lubricate so you don' t have the same issue.
