The inner seals are all you need (front), no seal at the hub end. You will have to pull the axle shafts back and remove the carrier. I recommend pulling the axles all the way back and running a shop vac hose down the axle tubes to get sand and debris out so you don't contaminate the new seals when you put the axles back in. Don't forget to put a little grease between the lips of the rubber seal so the new seals won't tear from being dry. Also, I put a small bead of rtv around the outer part of the seal where it goes into the housing to avoid any nuisance leaks.
