If they are anything like the Cherokee, the first time apart could take
some convincing to do depending on your local rust factor.  I recommend
you start soaking the hub rim and bolts with a good penetrating oil and
use it several times over a couple days first.

You might need a 12 point socket also.

I also find having a sacrificial bolt that fits the back side of the
steering knuckle is handy so the OEM ones don't get bent.  On the
Cherokee, you have to hit the three large bolts on the back side of the
knuckle with a BFH after you have loosened them off a bunch to get the
hub moving.  A 5 lb Hammer can be needed or a really good thump with a
framing hammer or a good tap with a 10 lb. or BFH.

I find cutting the wheels side to side helps to get room to work on and
hit those bolts.

I think the book says to tap the side of the hub with a rubber mallet I
think to pop it out.  Yours might even be that easy, but....

Good luck!

About the rust ... if it's real bad, and you can't separate the hub,
just replace it as well. At least the problems on the passenger side so
no safety issue (in 2wd) ... assuming command-trac.
