my landmark slides

[jshelley]

my kitchen and living room slides drift out, any ideas?

Are you saying that the slides drift out during travel?
I have had that happen. Turned out that there was an internal leak in one of the hydraulic rams.
A fairly easy fix if you are a DIY person.
Until you get it fixed you can use a ratchet strap underneath to keep the slides in during travel.
Refer to the service manual in our Tools section located here to troubleshoot

You may also want to close off the side isolation valves to help isolate the problem slide. Otherwise they are all connected together via the hydraulic lines.

the two hydraulic slides leak or drift out after a few weeks of closing my unit down for a few months, they operate in and out fine....just drifts out after a certain time.....
does each slide have a pump and cylinder?, or is there one main pump w/ hydraulic lines to each slide?

There is a single hydraulic pump that operates all the hydraulic slides and the levelup system.

On Landmark, you probably have a separate switch to operate each of the slides. Each switch opens and closes a valve for its respective slide, and powers the hydraulic pump.

Each hydraulic slide has a separate ram that is extended or retracted to move the slide.

The drift could be from hydraulic fluid getting past the seals in the ram. Or it could be fluid getting past the valves.

But it's unusual to have 2 slides doing this on a Landmark, because the mechanisms are separate. Unless you have a Landmark where a single switch operates more than one slide. If that's the case, the valve is probably not closing fully.
