It DOES NOT SAY what these magical specifications are, or where they can be found. I can tell you that THEY ARE NOT ANYWHERE IN THE DIFFERENTIAL OR REAR AXLE ASSEMBLY MAINTENANCE MANUAL INSTRUCTIONS, AS i HAVE BEEN THROUGH THEM PAGE BY PAGE.
Anyone have an idea of the amount of differential lubricant to install in the differential?
Thanks very much!
Here's a post I did when I replaced my gear oil. I hope that it is helpful.
Like pizzaguy said, fill it until it drips out. IMPORTANT: Make sure to remove the fill plug first, drain plug second.
