Hi Bill.

The differential mounts on four studs that extend down from the frame.  The 
diff mounts must be lowered enough to clear these studs, approximately 4 - 
6 inches.  You will have to disconnect the driveshaft to get it to drop that 
far.  You may have to disconnect the half shafts as well.  Once you have 
gone that far dropping the differential out altogether is no more work, 
really.

Oil can leak out of any seal and joint.  There are three seals, pinion and 
two half shaft seals.  There is a gasket where the front and rear sections 
join together.  This joint can leak.  Another potential source are the fill 
and drain plugs.  Using pipe dope on these threads can help.

Cheers
