they said to run them dry, but I don't  find any recent mention of that.  
There was a thread on this topic  last fall that was both pro and con for 
greasing.
 
    There is no con. The 'con' position' was  previously stated such that 
since they couldn't find that the manufacturer  didn't say not to grease was that 
it was okay to. The LXC Prime Directive  states to "DO what the manufacturer 
says" and the usually unstated second part  of that is to "NOT do what they 
don't tell you". If they say to do it - do it.  If they don't say to do it - 
don't do it. 
 
    You don't grease them. It just attracts particles  and junk out of the 
air and promotes premature wear. It spins at 1 RPM - it  doesn't need to be 
greased.
