Today, I took everything off the trailer (wench, wheels, bunks, bow roller, center pad, and the guide rails. The only thing I didn't get off yet wer the lights, and the center keel roller. It has the caps on the outside of the bracket that holds the pin. They, as most of you know, are a "hat" shape. How are they removed? Looks like they are pressed on. I tried prying with a screw driver, but I didn't want to break it or bend it up. It did give a fight as is while I pulled on them. So, any suggestions on how to remove the end caps holding the roller on? Thanks.
