    Where is the Drain plug for the Rear Diff?

    I see the lines to and from the cooler but what does the plugs look like? I can seem to get pics and a detailed step by step.


    Thanks

    Drain plug is on the bottom, pointing straight down. Fill plug is on the passenger side of the diff. Both take a hex bit driver. Always unscrew the fill first to make sure you can get it filled before draining it. Not sure where the cooler connects but I think it's through these two locations.
