It does not sound right, particularly if it has been greased. I assume it is stiff without the weight of the trailer on it (and it should not be too stiff with the weight of the trailer as that would overload the towing vehicle). Can you remove the whole thing from the trailer? If is, is it still very stiff? If so, it sounds like it may be bent or have a defective thread. Take it up with the dealer or replace the whole thing.
