i used a piece of threaded rod with a washer the size of the new seal on one end and the head of a sledge hammer for the hammer part of my slide hammer on the passenger axle seal.
they say a 1 3/4" socket is the perfect size to drive in the driver side seal.
don't forget that the driver seal doesn't have a stop in the tube so it would be easy to drive it too far. my passenger seal did have a stop in the tube. so just make note of the depth before you pull the old ones out.
other than that, you'll need a dead blow hammer for making sure the carrier is seated good when you re-install it.
and you can either use prybars or a come along to get the carrier out. i lined the hitch on my dads truck up with the differential and put a small chain around the center of the carrier and had him slowly crank the come along while i was under there to catch the carrier.
oh yeah, penetrating fluid, 3/4" breaker bar, cheater bar for the breaker bar, 1 11/16" socket, torque wrench capable of 175 ft. lbs, a couple cotter pins, new diff fluid and rtv, 14mm 12pt. socket that will fit your torque wrench (i couldn't get the top bolt on the hubs with the 1/2-3/8" adapter so i bought a 1/2" drive socket) and the seals. a good scraper (the razor blade type) and some 400 grit sandpaper get the sealing surface nice and clean too.
