the only way to know what differential you have is to take off the cover and look at it. The spin test only works for certain types of differentials which are not worn out.

Makes sense. What weight and how much oil do I need for Dana 35?

Taken directly from the YJ FAQ (frequently asked questions):

What fluids do I use and how much do I put in my Jeep?
*Axles:
- Gear oil - 80 weight for light duty and normally cooler climates - 90w120 weight for heavy duty and normally warmer climates Note: Some rear axles are equiped with factory posi - a limited slip additive must be put in with the gear oil to extend and protect the limited slip action
Dana 30 = 2.5 pints
Dana 35 = 3.5 pints
Dana 44 = 4.0 pints


I use 75w90 as I recall.
