drivers side fifth wheel front hydraulic jack not holding

[Coriley]

Everything has been fine. When moving the trailer, we found the the drivers side front hydraulic jack was not holding the fifth wheel up. We had to place blocks under to stabilize for the mean time. Can anyone tell me what the problem might be or what to check for? The other side seems to be working OK.

Possibility it is a valve that is not closed all the way. It could be a seal is leaking.
What do you mean by, "when moving the trailer, we found the..... was not holding the 5th wheel up."?

The fifth wheel is currently in inside storage. Sometimes the storage owner moves trailers around using a fork lift to get to another trailer in behind. After moving it they noticed the front jack was no longer holding on the drivers side front jack.

Is there a good way to determine which the problem might be? Either the leaking seal or the valve that is not closed all the way.

most likely internal seals are damaged letting fluid past; if that's the case Lippert recommends replacing the complete unit

Here is a link to info on the leveling system. It can be found in the Tools section located at the top of each forum page.
You will find information that will help you.

The best way to solve your problem is as per the picture I have changed all the valves and both my front legs still drop. Go figure?
