Have oil leak above adapter, not at hose fittings. Very crowded location, line fittings are hard to get wrench on. Before I drop shaft from t-case so I have room to work, I want to know: are these releases I am seeing on pipe fittings ? My eyes are not good so only my camera has been there. Secondly, if I need to drop shaft to get adapter out, can I just get away with removing the cap bolts and 4 in the rear end flange without needing to do anything besides reinstall later ? Am I missing anything ? Appreciate any comments any may have. . . .
