I have a note some of you may or not know already. Today I replaced the other boot that the critters didn't eat. It was still intact, but I like these greaseable boots. When I pulled the factory boot off, there was almost no grease whatsoever in it. It looked as if there was only enough there to help in assembly. If you have replaced your upper control arms, or are going to, I would surely think hard about using these boots now. Dang sure glad I did.
