Hi

There are a number of posts about similar problems.

They commonly are traced to a fluid leak some were either externally or internally inside the cylinders.

Our hydraulic system (2009) has valves in the control panel at the driver side front of the trailer. These valves can be used to isolate the slide cylinders. Commonly the owner closes these valves and waits until the slides move on their own. You may find only one of them moves and in the absences of any visible leak it will be the cylinder for that slide leaking internally.
