Hey LUCAS. MudPie is technically correct. The interface of freehub/cassette is not a high friction-wear area, nor is it typically a removal problem. However, if you are assembling a new rear end, I think it's a good idea to put a THIN coating of grease on all mating surfaces. Especially if you expect the bike to be exposed to water regularly, or if you live in a coastal area (salty air). My reasoning is not related to probs w/disassembly, but rather with corrosion protection on parts that are not regularly accessed for servicing. I hate surface rust on steel and oxidation on alloy parts, but then I also live right between the Atlantic Ocean and the Delaware River.
BTW...when I say THIN coating, I basically mean to smear some grease into an old rag and wipe the parts down with it, just to "wet" the surface with the grease. It's just a preventive precaution I take when assembling parts I don't expect to take apart regularly. You can use whatever lube you feel is good for corrosion protection, but I have found good 'ol wheel bearing grease to be pretty effective (and cheap).
I have an old "grease rag" in a plastic bag just for doing this when assembling stuff.
Whatever you do, good luck...............
