How many of you grease your own trailer axles?

Need to watch how hard you backhand them. You could hurt your knuckles. :-)
Just my goofy sense of humous getting out. That is what I do as well. 2 hours driving max and it is time to get out and stretch the legs, so checking tire and bearing temps, tiedown straps and lights is a good idea. Usually due to drain the crankcase and get another coffee for the road.
