Default H&H Landing gear sinking

Last year I replaced the entire landing gear set up on my Wanderlodge after discovering the the seals were all blown. According to the company these units aren't rebuildable (but thats another story) Since that time, when I have the system up and running, I get the occasional hydraulic unit creep like the bus is settling. Since I am parked on hard back dirt and am using a set of large blocks as a spacer between the landing gear and the ground , I don't know if the sound I am hearing is the whole shooting match selling into the ground or just the landing gear themselves sinking.

Let me also say that where I am parked the ground has a slope to it.

Anyone ever have this issue?

All three coaches I have owned would let out a clunk once in a while. Just seems a very slight leak back into the valve over time would drop the pressure just enough for the system to settle. Not a noticeable amount, just a noise.

I had a jack leak. Local RV service shop in Clearwater wanted $1,300. They said they do not overhaul them, just replace them. I went to HWH in Moscow, Iowa and had them take it off, overhaul it, and put it on for about $250. While there I had them do the other front at the same time. Good people. They know and ought to know what they are doing.

If your travels take you near Iowa, schedule an appointment. Sounds like you need them all done, and you may have some leaking solenoid valves.

The told me the front jacks could be rebuilt for $457 + shipping. Had it done in Portsmouth VA for $360 each. He said they have to cut it apart and weld it back together using a lathe.

Sorry fellas, but they are rebuildable without cutting them apart. Cost me $10 for the seals for each jack, and did it at home. Now, they are put together well and HWH puts a ton of lock tite on the nuts, but it can be done.

I even have some old ones from a friend, who bought new ones, at show and tell at WOG, some years back, and if I can remember, I will bring them back this year.

Now these are the straight down ones.

If your jacks are like mine, the rear jacks are on a swivel mount and the front jacks swing aft as they retract.

If you are not on hard, level ground (like cement) and you lift the drive wheels up high enough to take some load off, the bus can slide forward on the dirt or gravel as the main, aft jacks swivel. The front jacks will just fold as the bus rolls forward off the jacks about a foot.

It stops when weight gets back on the drives which are the brakes with the parking cans.

I learned the hard way and when the rear jacks swiveled, they broke the hydraulic fitting screwed into the top of the rear jacks. I wasn’t under it - I never go underneath without shoring the bus on the frame.

The same thing happened to me when we first got the bus in 2000.
The rating on the jacks seemed enough that I could lift the ENTIRE bus off the ground....thought I would give it a try.
Wife inside working the controls, me outside to see what happens...
Bird lifted up all right and THEN fell forward off the jacks!
Wife screaming inside...me wondering what had happened.
Broke the hydraulic lines on both the rear jacks.
When I had them replaced, I had them make them an extra 12" longer in case I fell off them again and I wouldn't break the fittings again.
BIG lesson learned that day...

I thought it was an easy rebuild. You have to use a torch to heat the end nut to get it off because the factory uses Loctite. Each one of my jacks took 6 seals to rebuild them, the photo only shows 4 of them but my cost was $23.00 per cylinder.
