    First Gen Front Differential Fluid

    I really haven't been able to find a definitive answer on the forum. What type of fluid goes into the front differential on a first gen (specifically 1992) Explorer? The manual just says "4x4 gear oil" as does the computer at Advance Auto. I just want to be sure exactly what to put in...

    In a 94 Explorer what oil does the front and rear differentials take?

    I got a 94 Explorer 4.0 L Auto 4x4. The axle code is D4. What oil and how much for both the front and back?

    Which grade of oil do I use in a rear axle differential?

    I have an open differential (non-LSD)- owners manual call for 80w90 but i notice in many explorer threads that 75w140 is being used even in the open differentials. Is this advisable? By the way, I'm changing the oil to try to eliminate rear end noise. Thanks
