30 to 50k is about an average service interval if you aren't having extreme conditions.
You can find a Do It Yourself for both the front and rear diffs here on this site's DIY section. They are for the 2nd gen Outback, but your 3rd gen should not be all that different.
2003 Outback 2.5 wagon: "Kaylee". 157,000 and counting.
Mods: 2004 Forester XT shift knob, Fumoto oil drain valve, HIR1 high beam upgrade. Also: More rust than I care to think about.
2002 L.L. Bean Limited 3.0 Outback wagon: "Mal". 103,000 and counting.
Mods: Scangauge II, Fumoto oil drain valve, and a decent bit of fixing up to do.
