Well I was adding grease to the fitting on my plastic bearing buddy type ( I didnt buy them, they came on the boat trailer when I got it) and the thing snapped off right on the grease gun and the spring went flying. Now Id like to remove this horrible invention (who was the genius who decided that they should be plastic?) and put on regular metal bearing buddies. How the world does this thing come off. I tried wacking it near the hub with a hammer and screwdriver to loosen it but it wont budge and I keep cracking it more. Does anybody have an idea how I can get these stupid things off? I still cant believe they sold those things. Just like a metal one except all plastic. Thanks in advance. Bob
