Definately a weekend job. Drain the rear diff before you start as you need to remove the drive shafts. Rmoving discs from hub is a pig, but bolting to spare wheel makes it a bit easier. Do wheel bearings and oil seals at the same time, the seals don't like being disturbed, if they need done later, you have to dismantle the hub all over again. 52 mm box spanner/socket is needed to remove hub nuts, read manual carefully before replacing nuts,the inner must be tightened to approx 90 lb/f (to seat the bearing) then slackened right off before final tighten to 9 lb/f.
