installing an Aussie in a dana 30 is not to tough however you do have to remove the ring gear from the carrier to install the locker.

You just need to make sure that you make the ring gear in relation to the carrier and install it in the same position.

you will need to get a roll pin punch to remove the roll pin that hold the center pin in place it is only a couple of bucks at Harbor freight.

other than that the only special tools you will need are a torque wrench, rubber malet or dead blow, and some red locktite for the ring gear bolts (they will back out if you don't put red locktite on them)

If you need anything else just let me know I have a full factory service manual for the TJ
