Just thought I'd mention this: I was finishing up the installation of a new RokTec lift kit and decided to throw a little grease toward the suspension parts, ie, swing arms and such. I found two zerks that would not take grease so I pulled them and found they had never taken grease. They were as dry as a popcorn fart in a sand storm, as were the a-arm shafts. They were both 90 degree fittings and when I disassembled them I found the part with the check valve was not functioning. This is a pretty new machine so I'm hoping no permanent damage was done. I also found the rear swaybar was dry. These fittings worked okay, they just hadn't ever been greased. Polaris "Quality Control" is definitely in question. You guys migh want to check all your zerks.
