Pack the U-Joint?

Logan,
Well!------I don't know! The top of the "puddle" would be below the outlet into the torque tube and the tube has a seal in the front. I don't think "VERMIN" could climb a hill steep enough to cause oil transfer. Doing this couldn't harm anything. I just feel that the oil would do a better job of creeping into the sleeve type u joint cup & cross. I don't see how grease could work it's way into this critical area because of centrifugal force just throwing it to the outside of the area.
Our club's biggest booster of grease packing just recently wore out & broke his u-joint!!
Originally, I think they depended on some escaping oil from the rear trans. bearing to lube the joint somewhat. Bill W.
