How many of you grease your own trailer axles?

Works on semis with the 10s of thousands of miles they put on in a year. We had a couple that both drove their Freightshaker, 100k in 4 months. There was a few others that were similar.
I agree. My thoughts.......Most semis have a great maintenance schedule and most of the small stuff would be caught before it became big stuff. If folks can't keep their bearings greased, they would probably miss a weeping seal. Hit a rock, the sight glass breaks unknowingly.....stranded.
