Has anyone replaced one and if you have, how hard is it on a 1-10 scale. I watched a YouTube video for it and it didn't seem too tough at all. I have a leak in mine and know that's what needs to be replaced for sure. My wife wants me to take it to the dealership, but I'd rather save the shop fees and labor.
Changed mine twice-easy to do. Once you remove the toilet and turn it around you can see what you have to do. Be sure to set the toilet on a towel to soak up any water that leaks and be careful you don't over tighten toilet when you reinstall. I go back after a couple of weeks and retighten the toilet.
