Isuzu Repair: axle & transfer case lubricants, limited slip differential, gear lubricant

Question
I am changing the axle (front and rear) and transfer case fluids in my 1998 rodeo 4x4 (automatic).  How do I determine if I have a limited slip rear axle?  Also, what are the best brands and weighs of oils to use in the California valley?

Answer
Well a limited slip differential would have a button or switch in the car to activate it Lowell. So if you don't have a switch or button then there's your answer. As for the transfer case it recommends any good quality engine oil like  10w-30 or what you prefer. The differential lubricant is a 80w-90 GL-5 type gear lubricant. If you have any further questions please let me know okay?
