LOL Nipples...
Thanks, I needed that.
just so you know for future reference, they are tech. called Zerk Fittings... Next time you type nipple, there better be some boobs attached to those nipples (*EDIT* female Boobs)
a little FYI also, non-grease fitting u-joints are stronger than ones with grease fittings, since there is not bore accross the center of the trunions to provied the grease, they are just simply stronger. this does not mean a non-grease fitting U-joint can't be serviced, but you will have to putt the joint out and remove the caps, just a little dollup of grease in there and put back together.
