Default Re: 33 Tranny to Driveshaft Oil Leak

And yet again this comes up . Pic is factory service bulletin for 1934 . The difference with the u-joint lube is it is thickened with tallow . Melts at the touch . Like REAL water pump grease . If your driveshaft seal is good and installed the proper direction and if you do a good job on the clam gaskets-speedo turtle gasket SAE 140 works great . Actually I use SAE 140 in the steering,tranny and rear also . BTW " low melt grease " like cornhead grease has a dropping point of 450 degrees . Cylinder oil with tallow thickener has a dropping point of about 95 degrees .

Check the rear baffle in front of the rear bearing .
It should be right against the outer race .
If this is not right way too much lube will get past .

Ford didn't think the design of this was bad as it never really changed thru 48 .
