I plan to change the engine oil and final drive fluid tomorrow. I won't ask the question to start an oil preference discussion as I have made that decision. What I need to know is the specified weight for the final drive. If I didn't know any better I would use 80-90?
Original 3.70 as far as I know. Wish I had lower gears and limited slip. I run 4.11 possitraction in my old camper hauling trucks. Hills are no problem, MPG not so great.
