HWH jacks

[Eric]

The most likely cause of fluid under your leveling jack is debris that has
gotten drawn into the seals on your leveling jack. It is not uncommon for this
to occur. It's happened twice to me in six years. This is usually corrected by
raising and lowering the jacks several times. However I have to believe that
the repair shop must understand this and I expect has tried this. The fact that
they want to replace two your jacks....wow. The only reason that the jacks
should be replaced and not repaired is if the shaft is scored. In my opinion
that is unlikely and an expensive repair.

I once went to the HWH factory. I asked the technician how often he has seen
the large rear jacks on our system replaced. He said that the BB's had the
largest of the HWH jacks and he had never seen one that needed to be replaced.
Replacing the seals in the hydraulic jacks is a routine job for most hydraulic
repair facilities.

I guess if I were there I would ask the shop to remove the jacks and have them
sent to HWH for evaluation/repair if raising and lowering your coach several
times doesn't clear the problem. After the jacks have been sent back HWH you
could leave the facility and come back in a few weeks to have the repaired jacks
reinstalled.

If the "HWH facility" you are at is recommending replacing two of your jacks and
not repairing them, I would be suspect of the shop. I am not sure I would want
such a shop to be turned loose on my bus. If your bus is settling (lowering)
slowly in time it can mean two things. Oil is leaking out of the system
(usually a lot of oil) or as mentioned earlier, a solenoid valve or valves are
leaking oil back to the tank.
