I'm going to say yes to this. I didn't think so when I first put my 881's on, but after a few days my CV's started spitting out grease on both sides. The diff drop kits are cheap so its not a big deal there...the problem comes in when you decide not to reinstall the original skid plate and go get budbuilt skids instead....then the belly plate....then the gas tank skid(DUHOCKEY!!!AHHHH!!!!)...and so on and so on....
