this ^ when they take the rotor off to remove the axle they will see that the entire interior of the rotor hat (ebrake assembly and all) will be COVERED in gear lube.
realistically replacing both is a stretch, yes its a common failure, BUT because it is a common failure there is no need in spending the money before its required (and we all know it will eventually be required). ONE axle seal at my dealership costs from 290-430 dollars (dependant on the axle in the vehicle) and there is no overlap between doing both so your talking 600-860 dollars for repairing both (at the dealer of course). Bearings must be replaced with the seal as there is no way to remove the old bearing without cutting it off, not to mention even if there was it would be less than smart to not replace it for no additional labor since your in there.
Also for a diff overhaul (just replacing bearings) your looking at 1200 +/- dollars between the new seals required, 4 bearings, gear lube, and 8ish hours labor, that would make that a little overkill as far as preventative maintainence goes.
