You really have to crank down on that bolt too. I had a little spin too, so I used my dremel to scuff up the tapered faces good and used blue loctite (all I had). If it comes loose again, I'll get in there with more dramatic knurling and go get some red stuff. I noticed it mainly on the right side since pushing down in effect loosens that bolt. It would be a great place for some left-hand threaded bolts!!
