HWH Leveling Jack losing it's lift

[wlf00]

I have HWH leveling jacks on my coach and keep the coach leveled in my back yard. When level, the passenger rear jack is extended the most. After a couple of weeks, I noticed that the passenger rear of the coach seemed to be settling. I can re-level the coach and the rear will come back up into place.

While at the Winnebago Factory Service Center a few weeks ago, I told them about it. They said that the hydraulic fluid level was a little low and that was probably the problem. They topped off the fluid and leveled it for a day while in the shop and it did not settle at all during the day.

Now I am back home and noticed that after three weeks, the passenger rear seamed to be a couple of inches low again. There is no noticeable leak around the jack cylinder.

Any suggestions?

Thanks,

It is likely you have a solenoid valve leaking by. Not an unheard of problem with these valves.

Locate the HWH assembly, look for a laminated tag on the wires coming from each valve (small cylinders) and find one marked RR. Be very careful not to introduce dirt into the manifold.

You might remove it, clean the seat and re-install and test. If it still settles/leaks then you might want to get a spare and replace it.

I carry a spare now since having the same issue.
