    Mine has always sorta spewed grease out of the bottom end. It would seem to me that their should be some sort of plug in their to keep the grease in, I thought I saw them plugged on military Blazers. Should mine have one? If so where do I get one?

    Do you mean that hole just behind the lower u-joint? You can't plug it, when the driveshaft shortens, the inner part of the shaft forces air out that hole at high speed. It's sorta like a bicycle pump. As it lengthens it's on the intake stroke... [​IMG]
