The drain bolt is locate on the passenger side at the bottom of the diff. You need an an allen socket (I forgot the size). The fill bolt is just above it. They dont look like your oil drain bolt at all.

Remember, always take out the fill bolt before the drain bolt.

It's recommended that you get a long pipe to assist the allen wrench for more torque. It's torqued down to 39 ft-lbs. GL!

A 10mm Allen bit and a breaker bar or a STURDY ratchet is all you need. A oil pump or suction gun is handy to have.

I use Red Line 75W-90 in my rear end, I used Mobil 1 before that.
