O.K., I bought one of those needle adapters. I see how it fits into the grease gun, but what is the correct way to use it on the u-joint?

It was also suggested to me, that if I could find a longer grease fitting that would work, to stick it in there, shoot in the grease, then put the original one back in.

Maybe this weekend I can get under there to mess with it.

Thanks for the tips folks,
