differential fluid - how to check drain and fill
The only way to drain is take the bolts out of the cover on back (13mm), take a hammer and thin chisel and peck the cover off. Clean the cover and rear end, put a thick layer of black permatex sealer on the cover and mate it back up to the rear end, install the bolts. To fill there is a plug that is the size of a 3/8" extension on left side front of rear end. Take it out and put fluid in until you can touch it with your finger inside the hole re install plug. 3qts of 75w-140w rear end grease.
