Strap it to the back of your 4-wheeler and drive around for about a half a day. Dust will get into the ball mechanism. I know that it sounds like I'm being sarcastic but I'm not. It works. Before doing this, first check the tension adjustment located on the handgrip. Adjust it tighter if you have any adjustment left. Or you could spray contact cleaner into the ball mechanism. It is a dry type cleaner. Do not relube the ball unless you need it. Then use it sparingly until you get the desired amount of movement. Last option, buy a new one. fatrooster.
