Trek seemed to put a bottom bracket cartridges in their bikes at that time that were one component level down from main
components. So, the BB may be a Flight Deck 105 BB.
I any event I'd have LBS repack the freehub and bottom bracket/cranks with new grease since it is 10 yrs or so old.
You can find out then, if curious, what model BB you have.
