Sticky hydraulic levelers

The levelers on my class A work well except when it time to pack up and leave. Often 1 or 2 will stay down. I now carry a 6 foot 2x4 and a wood block to push them back into the stored (up) position. Each leveler has two springs attached to the ground pad and the springs seam to be applying enough force that they should pull the Pistons to the up position. In owners manual says very clearly not to lubricate them in any way but after 11 years it does not seem unreasonable to expect something to have dried out a bit. I have tried moving them up and down to try and free them up but this has not been enough. Is there some thing I can use to provide more lubrication? Any other suggestions?

    I have those cylinders, but have never had a problem w/ them.
    But if and when I do, the first thing I will do is apply motor....or hydraulic oil to the shafts and cycle a few times. There is absolutely no reason not to.

    IF your system is HWH, the sticking cylinders have bad internal seals. You either replace the cylinders or remove and have them rebuilt. Doug

    I use a silicone spray on my levelers, spray on and wipe off the excess. Some rams have a zerk fitting on the bottom of the upper part of the ram that needs to be greased. Like all systems they need to be exercised. I will run my levelers through about 10 cycles. I started doing this after I got this coach and noticed after a trip where they got used they worked a lot better.
