Slide Outs Slowly Coming out going down bumpy roads

[Steven.Daskam]

Hello everyone, I bought a 2009 Cyclone 3950 about 3 months ago, we took it out for the first time the other weekend. When we were going over the mountain pass and pulled off at a rest stopped I noticed that the slide outs for the kitchen and couch were out about 3inches. I closed everything back up and didn't have an issue until I started driving home over the pass and bumpy roads again. The slide outs go in and out just fine when I use the switch. I am concerned they are coming out while driving down the road. Almost like they are losing hydraulic pressure. Please and thank you for the help.

It sounds like you have an internal hydraulic cylinder fluid leak. I've had that happen.
You should be able to find the method for checking the hydraulic cylinders in the Tools section of this forum. Or right here. https://manuals.heartlandowners.org/?man=Slide_Outs/Rooms/Lippert

try closing the valves on the manifold, and if one of them still comes out, its THAT cylinder that is the problem.... but otherwise it may be a piece of debris in the relief valve.. which the relief valve CAN fail as well as a cylinder can... but the shut off valves will be the best troubleshooting feature you can use to eliminate and find the problem....
