It's time to service my 2002 Bontrager Tandem hubs. How? I have the gears and disc adapter off. Now what? One LBS (doesn't sell Trek) told me they don't need service but I have a squeak I'm trying to get rid of.

The star ratchet mechanism is very easy to service and should be cleaned and lubed every now and again, but does require the use of a very lightweight lubricant. Here are some links to servicing instructions:
