Yes. The u-joint is in question--not the real seal on the tranny (from what I can see in the pics). The u-joint seals have failed and is slinging grease.
ok, i got under there and two of the four shafts on the u-joint had a little plastic seal/ring. i tinkered with those a little bit and snapped em back in place. the squeaking stopped....for now. how hard is it to swap the Us out??
