Personally I’d say replacing the o-ring that seals the axle housing end to the hub bearing is mandatory. They start out with a round cross section. By the time they are disassembled.. no longer round.The 200 doesn't have a rear cover. You'd need to disconnect the driveshaft and pull both axles outward (they don't have to come all the way out, just enough to get them out of the diff), remove the fasteners then the gear carrier assembly. Reassembly requires a new paper gasket. It's a hassle job but not really especially difficult.
As it is you’ll need to separate the brake line from the backing plate to get it out far enough for the axle shaft to clear the diff.. at that point pulling the whole axle is trivial, as long as you have enough room to the sides of the vehicle.
