Discovery 37T Levelling Jacks

Has anyone had any issues with the leveling jacks (Power Gear) not holding the coach level? This coach is a 2002 Discovery and is new to me. When we raise the coach to level it, over night you can hear a chunking or creaking sound coming from the rear jacks. When you wake up in the morning, the rear jacks have retracted enough that the coach is no longer level. The right rear jack also has issues with retracting along with the others and quite often I have to lever the cylinder back up into retracted position. I have checked the fluid level and it is full right up to the threads in the plug hole. Any help is appreciated.

First wanted to say Welcome!

On your jack legs look at the bottom of the cylinder and check if there is a grease fitting there. If so a shot or two of grease should help. Make sure the chrome cylinder is clean and spray it with Silicone Spray and wipe it down. Check out this forum post.

As far as leaking down, that sounds like a bad valve causing the fluid to leak back into the reservoir.

I sent you a PM

There is a electric solenoid valve that opens and allows fluid to flow into the jack you have selected. The right rear, left rear or both front if the front is selected. If there is no visible fluid on the jacks, then the fluid is leaking through the elec. solenoid back into the tank.

One of my HWH hydraulic jacks exhibited the same symptoms. As noted above, it was one of the electric solenoids for that particular jack was leaking back into the reservoir. Replaced the solenoid and all was right with the world once again. Sounds like maybe you have two that are bad.

So, get a magic marker (black), raise the coach to the prescribed level position and then crawl under the coach to each of the jacks. With the magic marker, mark a line about 1/4" under the bottom of the jack housing (on the silver part itself) on each of the jacks.

The next morning, crawl back under and see which jack(s) have retracted enough so that you can see the magic marker line any more.

That will tell you which are leaking down.

Then find your hydraulic pump and it should be connected to a manifold of some sort with the electric solenoids mounted on the front, or rear, or side of the manifold.

You will need to get access to a service manual to tell you which solenoid is for which jack. Should be able to find that on line.

Good luck

My Revolution had the same problem with Power Gear levelers and after much research I changed the hydraulic fluid and the problem went away. The problem is from dirty fluid. There is a procedure on Power Gear's web site for bleeding the jack system.
