Jay,
I applaud your bravery in diving into the rear end. However, it needs to be said for the benefit of other go-getters out there, don't try to fix a rear end until you know that it is broken. These axles are very reliable and long-lasting, and seldom need more than seals or outer axle bearings. If the ring and pinion, or other internals are bad, you will know right away when you drive it. I hope you find out what's wrong soon. I can't wait for the DOH! moment.
When you get it back together and it works perfectly, you can scratch it off your bucket list, and look down your nose to your buddies who have never done it.
Carl
