Ultimately I found that using the small center bushing remover first to get that portion out of the way, cleaning the fluid if there is any left so it doesn’t get in your face, Then using an air hammer with a chisel bit to push the bushing out. It takes literally 30 seconds, if you want to make a couple cuts through the outer shell with a saws-all, collapse it in a little then chisel it out that way works as well. But seriously F that removal tool for the steel subframes, again with the aluminum it works very well. Just my .02
