As said above. Direct bolt in. Unless you have an actual locker no need to use any special oil. Having said that I have a Detroit locker in my rear diff and until I put the real good oil and additive in it it sounded like the rear end was going to blow up. Now it just kinda clunks a bit as it disengages. Enjoy your move away from 1 tire fire!
