Great job on both the explanation and the pics, THANKS. Just printed off a hard copy of your report and will put it in my manuals binder just in case. I was wondering what type of lube hapijac recommends to use ? I can't tell from pics other than it appears to be a white grease but is it a extreme pressure type or synthetic or ?

Forgot to mention that the outer tube does not have a coating inside. But if you need to paint it, now would be the time! Good luck with it you all!

I personally like to see the internals now that I have done this. It really does not take very long to do either. Zerking it is not a good idea because the internal tube moves inside the other for one...lube would only be able to get to a very limited part of the mechanism and you would have to pump in a huge amount, A big mess if you ask me...I lubed not just the entire worm gear but the bearing and square plate, where there is no way to get it in there unless you take it apart....sorry.

If all that dis-assembly is just to lube the screw drive, why couldn't you put a hole near the bottom of the exterior tube and lube the gear just above the carrier so it carries the lubing up the screw? That way it wouldn't require dis-assembly each time? Would that NOT work?

Could the outer jack tube be drilled and tapped and a zerk fitting be placed in a area such that grease will get to the worm gear and to the bearing? Just a idea. It wouldn't be very difficult to drill and tap the tube, and It wouldn't cause any structural issues to the jack assembly.
Anyone done this yet?

Great post. I think these types of post are of the most value to RV.NET readers. It helps people to understand their equipment.

Good post and very helpful.
The factory coating seems to be prone to rusting and I like the suggestion to consider powder (or other shop) coating.
I wonder if now would be a good time to add some strategically located small zerk fittings, to permit introduction of grease and possibly extend interval between tear-downs?
What is thickness of square tube section? This would help in calcuating maximum size hole that could be drilled and tapped in tube without compromising structural integrity.

Do you have any rust on the outside, and if so, did you see any rust on the inside of the column? I've had rust and paint popping on the outside which I've spot repaired, but have wondered about the inside. Concern is integrity of the column but it does look pretty stout (thick).
What about the "nut" at the top of the black column? That looks like it carries the load. It looks like a welded plate.

Is what is left in the outer tube, suitable to the power coat heat of 400 'f?
Cause mine are rusty too.![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/rolleyes.gif "rolleyes")
