Doug, I've been doing some reading that tells me this about rebuilding:
1. There may be a "Kit" and that makes the job sound DIY-possible, but
2. It's a welded jack, making the rebuild a pro shop job because the jack has to be cut (probably on a special lathe) and then we-welded (true and oil-tight)
That these make it a replace or professional rebuild?
1. ALL motorhome jacks can be removed without cutting off. The "welds" are too the mount plates for the cylinders
2. IT IS NOT THE EXTERNAL SEAL ON THE BOTTOM YOU SEE THAT CAUSES THE JACKS TO BE FORCED TO RETRACT. IT IS A FAILURE OF THE INTERNAL SEALS THAT CAUSES THE PROBLEM.
3. The only KIT for DIY is by Powergear. Powergear also have grease Zircs on the bottom collar. HWH does not.
4. Yes, the shiny part can get dirty from being exposed, but you do use WD 40 to CLEAN the exposed part, but is not neccesary for actual lubing
5. My comments are based on 30 years of working on HWH systems and when I state REPLACE or REBUILD, that is the ONLY fix, unless you want to continually crawl under and attempt to manually lube and wipe down the cylinder, which will work for a few times, then the problem returns.
