After the jaunt around town I no longer have the leak. What had me going was that I thought it was a rear main seal from where the drip was coming but it was a 2 inch puddle each drive. I must have moved the sensor that was loose just slightly when I was adjusting the valves. I had checked for leaks at the valve cover as well. It is so nice not to have any leaks except for a periodic drip of one drop from the 8 3/4 diff. maybe every other week. Happy camper today.
