where  does one get the protective cap that keeps the grease in the splines for the rear driveshaft?  while doin my SPOA, I found the rear drive shaft froze up tightet than richard's hat band.

I make it a habbit of greasing after getting back from every run. All the grit and mess that you pick during a run is hard on everything so 5 minutes and it's all greased up. At the same time I get to take a look at the whole thing and it makes me wash it right away.

Then I park it next to the shed until a few days before the next run....re-check two days before and get ready for play time.
