Thanks for the link OP. I think I am going to do this way for my two cars. After reading so many DIY's on this and watching videos, after looking through this link I finally get it.

I may be overthinking this, but I wonder what people use to clean up the grease out of that joint. Does it have to be some lint free towel?
