I got everything apart and cleaned up. the cork gasket came out in pcs so I think that’s is where my leak was coming from When I Lowered the tail shaft only an ounce or so came out do you think should change the okie seal ? I measured the shim on the torque ball housing and it measures.040 thick . According to what I read I should install the ball with the new shims until I have a slight drag correct? After I have everything assembled should I add gear oil to to the ball housing the 4 speed transmission has a plug to the rear . Thanks for everyone’s help Garry Rhine
