Gear oil is just fine for the differentials.

The specified oil is 75W90.
You have to remove the covers to get the old oil out.
You will need new gaskets for the Dana 30 and 35.
They are the same as on the XJ Cherokee.

Just be sure the rear has no posi setup. It will take posi additive then. 80/90W is better than straight 90 and 75W90 is synthetic or synthetic blend.

What did the D30 rear come from? Did you mean Model 15 aka Dana 35?

Multi weight is better, as it lubes better when staring out cold.
