Ok so i went out there and crawled around and shook some stuff haha.
I decided things were not looking quite like you described though i think i figured out what the u joint is.
Then i took a picture from the front of toward the back. there doesn't seem to be anything that comes near the drive shaft.
here is a picture up at the front of a little rubber thing. Not sure what this is.
and just for good measure a picture from the back looking forward.
So am i looking at the right things under there?
