Most of the leaks in the rams are the internal type where the fluid seeps past the seal into the unpressurized side of the ram. You won't see fluid but the jack won't hold pressure. Lippert does not rebuild the rams so you will be looking at a replacement for it. I've already had this happen but it was one of the main jacks in front.

If you see fluid on the ground near the rear of the trailer I would first look at the connections at the top of the jack. The rears have therm exposed. One of my fittings broke about 18 months ago. They are standard fittings available at any hydraulic shop. As far as I know, the only fittings inside the rig would be from the slides. The jacks should have hoses with no fittings in line until they reach either the manifold or the jack locations.
