Lubricating the hitch jack?

Have any of you done "maintenance" on your H & H electric tongue/hitch jack?

I found the directions and think I can get the cover off. I understand that I am to use Lithium based gear grease.

Is it simple? Simple is best for me.

If it's like ours, you just unscrew the 6 machine screws that hold on the cover, and add a daub of grease. Put the cover back on, and you're finished.

Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.

If it's the newer style that A/S is using, like the one on my CCD, there are onlu 2-5/16" hex heads, one on either side of the plastic cover holding it on. Remove and lift the cover and the gears are right there. That's it!

Never taken my jack apart yet but...

I have fiddled around with two similar jack/screw items before.
One was the jacks on my old slide in pickup camper and the other was the leveling adjuster on the three point hitch on my tractor.
Bear with me...
I learned about them from having both of them fail.
All of these jacks use a crank (or motor and gears) to turn a threaded rod which is mated to a special nut which does the acutal raising and lowering. On both of the items I mentioned it was not the gears that failed but the nut on the threaded rod.
Lack of grease on the rod caused the threads to wear out out in the nut.
It failed. On one occasion dropping one corner of my camper and on the other causing my plow to drop. Both could have been disasters.
If and when I get around to greasing my Airstream Jack you can be assured I will do more than pop some little cover off and add grease to the gears.
I will also take it apart far enough to allow me to grease the threaded rod and nut. Because that nut is the Holy Grail of the jack

" understand that I am to use Lithium based gear grease."
Is that true for a 1978 version too?
