you have to remove the little retaining “clip”
its kinda horseshoe shaped with a small tab at the top of it.
pull on that tab to slide the “horseshoe” retaining clip and then pull the cartridge straight out.
sometimes they can be very hard to pull out and you have to use a moen stem puller…pretty expensive little tool, so if the tool is needed hopefully you have a friend that has one so you can borrow it!
