It would be nice to use something like assembly lube. Honda's Moly 60 paste (60% moly) would be ideal, if you could figure out how to get it in there. Dow makes a very similar product.

The biggest advantage of Moly, besides bonding to metal, is the fact that it is just as good a lube when it is dry.

Sure is messy stuff though - gets on everything, and comes off nothing.........
