Changing the Differential Fluid Tomorrow

Changing the diff. fluid on my own for the first time tomorrow morning, and was wondering about fluid temp before changing. I always run my 99 TJ Sport at least around the neighborhood a couple times to get the oil warm before changing as the heat thins it out a bit and helps to get the oil to drain more easily. Should I do the same for the diff. fluid, as it is an even more viscous fluid than the 10w30? If so, how long should I run in 4wd to get the front warmed up enough? Is a trip or two around the neighborhood sufficient, or does it need more than that since it is so thick? Also, I haven't checked the repair manual yet. Does anyone know off the top of their head how much gear oil the Dana 30 and 35 take?

Thanks to all in advance!

I changed both mine about a month ago. It must take quite a while for them to warm up. I used a cheap squeeze hand pump that I have for use on kerosene and adapted the hose to fit the differential fill opening. Something plus or minus a quart, (I bought a gallon and have plenty left. ) Old fluid really smells bad.

The Dana 30 is about a quart and a half if I remember correctly. The 35 I couldn't tell you I swapped to a 8.8 before ever changing it.
