But, HyGain said that the grease should be checked after 3 to 4 years to determine if it is 'adequate' .  So, I cracked the gear case and found lots, lots of yellow-tan grease that was still soft.  I could re-distribute it to be mainly on the gears where I assume it started its service in the gearbox.

I now use white Lithium grease in most of these applications.  It's good 
and it stands up to the elements quite well.
I have a rather large array "up there" and went through a pair of 
HDR-300s in just a couple of weeks of windy weather. They would have 
held the antennas fine, but I wanted to use them even if the winds were 
high.

That sounds like the standard Lithium grease available in tubs at most 
auto supply stores at reasonable prices.
