The Sturmey-Archer AW is meant to be lubricated with oil, not grease. I would NOT recommend following the above advice for two reasons:
1: The hub isn't meant to be lubricated with grease! It's meant to be oiled! Don't assume that you are smarter than the designer of the hub. Grease won't do a better job.
2: There's a little oil port in the hub shell. This allows you to pop the little plastic or metal cap and squirt some oil in there every once in a while. It's a 30-second operation that needs to be performed maybe every year or so - 6 months if you're really anal retentive about it. Disassembling and greasing the hub is needlessly labor intensive. You'd be wasting your time, for no benefit. Furthermore, while the AW and other three-speed hubs aren't as complicated as they are made out to be, taking them apart and putting them back together again is out of reach of the skill sets of (or "want to bother" sets) of most home mechanics. Squirting oil with an oil can, though, can be done by any moron.
The hub has a freakin' oil port! Make use of it every year or five or so, and otherwise don't worry about it.
Hrm, addendum: it may be that the newer AWs switched to grease lubrication. I don't know, I'm not an expert on these hubs. If so, my advice: don't worry about greasing it, just ride the silly thing. It'll be fine.
