If you are reffering to the front wheel seals in the rotors, then Txmudder's way will work fine. If you are talking about the axle seals in the pumpkin. Yes you have to remove the carrier, its not a big deal as long as you are careful and mark you bearing caps for which side and also up. Then be very careful when you pull the carrier, make sure to keep the races on the right sides and to also keep any shims that may be presend on the right sides. As long as you put it back the same way it came out and with the same parts on the same sides, you wont have to reset your gear pattern, I have done this myself.
Now, once you have it out, use a long steel rod, I used my hydrolic jack handle, and tap them out to the inside, they are usually pretty easy to get out. Putting the new ones back in however is FUN, its a royal pain in the ass. Go to the hardware store and find a piece of schedule 40 pvc pipe that the seals fit into snug, buy a couple of feet and make yourself about 4 small 3 to 4 inch pieces of it. Use your hammer to drive the new seals in with the pvc as a punch. Take your time and be careful, they go sideways allot and you have to start again.
Also before you put them in, make a half moon shaped scraper with a long piece of steel rod, use that to scrape out the axle tubes before you put the new sealse in, otherwise when you put the axle shafts back in, you will plow all the dirt and crud right into your new seals.
