I suspect your zone valve has dirt in it. Zones are identified on the top of the pump. You could try to remove the valve and flush it out. First have to remove the electric celluloid around the valve then the valve unscrews. fluid leek is minimal. This worked for me once. If cannot clean valve a new one is about $80. To manual retract turn screw on face of valve the opposite direction it is in now. I think counter clockwise and retract slide. You might want to manual retract prior to cleaning. Put the screw back in original position after the manual retract.

Make sure the coach is level. Less stress on the slide.

The valve would also cause the slide creep.

I had a very similar problem last year with my sofa slide. Somehow the alignment rod got out of sync and bent one of the end gears. Before you do anything else, crawl undet the slide and you will see a rod going across the underside of the slide inside the storage area. There is a rack and pinion gear at esch end of the rod (one will be inside where the propane tank is) and make sure neither is bent in the slightest. If one or both are jumped out of the rack gear and bent you have a nig problem. If you search my posts from June 5 last year you can see what i went through to fix it. Good luck and i hope for your sake this is not your issue. If you need to PM please feel free to do so

There may be valves that allow selection which slide moves. That slide may be deselected. Manual or website?

I have called all of the mobile rv repair in the area. None are available.

Currently have a mobile hydraulics specialist here. He feels that it is a faulty seal in ram. Is removing ram and will replace seal

When you bought the unit, you should have gotten a small tool that looks like a flexible screwdriver with a hex tool on the end. This is to put into a drill and turn the jacks manually from the pump unit. You have to set the valves manually, too, though. You mentioned you're on a steep grade - is the unit level? If not, is it possible the large slide is simply binding? Also, if you're not level, check the outlet for the hydraulic oil in the reservoir and make sure it's not exposed. It may be possible to slope enough that the pump actually runs out of oil while there is still some in the reservoir. If it has run out of oil that way, then I would imagine you now have air in the system which would need to be bled out - that one's beyond me and I think you'd need a service tech and a lot of oil to bleed it from the cylinder end of things.

I believe that the flexible tool is for the electric slide motor not the hydraulic slide on the Berkshire. It may be different on your Legacy.

My Berkshire came with one. I saw on another thread about using Marvel Mystery oil in the hydraulic system.
