Replacement is easy. Simply air down the fork. Use a socket to remove the caps. Using a pry tool dig out your old valve (do not scratch inside the tube). Using a pencil or something similar push the new valve all the way in with the domed side up, the reinstall the cap. Air up to 100 PSI (using a sports needle without the side hole) to test and then reduce to your desired air pressure. It is very important to use a needle without the side hole as the hole can tear the valve and allow air to leak.
