Hello Everyone,

I have a auto leveling jack that appears to be leaking. The Jack is working ok.
The jack pad is damp with fluid, and the other 3 pads are dry. I also noticed that there is fresh fluid present on the pump and the ground once I left the campsite. Hope the attached pictures show well.

Any insight would be appreciated......before I take it to the shop.

I'd start by wiping everything clean so you can get a better idea of exactly where the leak is. It could be a bad hose, a loose fitting, or the seal on the hydraulic piston. The piston seal can be rebuilt by any truck or heavy equipment shop if you remove it and take it to them.

Thanks BF! I was able to get underneath, and it looks like the source of the leak is a fitting. I took it to a shop for confirmation, and they said the jack is shot.

I am curious as to how a fitting was leaking to a shop saying the jack is shot. Did you take it to a hydraulic shop? Did they take the jack apart and look the seals. Most hydraulic cylinders can be disassembled and rebuilt with new seals/wipers etc.

I'm questioning that as we speak. I took it to the shop first and took the picture afterwards. Unfortunately, I'm was not able to confirm that the fitting is leaking, but it sure looks that way. I'll be getting the proper tools to and some degreaser to check next week. I get your point and concur, I can't bridge what looks like a loose fitting to a full replacement.

I've had a hose connection come loose and create a leak. A half turn with a wrench and all was good again.

A hydraulic cylinder/piston assembly wouldn't be 'shot' unless deeply scored or pitted on the piston side. A seal is about the only thing that could be 'shot'. A rebuild should not be expensive, as I said, easily done at any shop that deals with hydraulics. If the shop didn't tighten the leaking fitting, I'd take a wrench to it, clean it up, and see if it solves the problem. A bit of spray lube on the shiny parts also isn't a bad idea, check manufacturer for type, some suggest silicone or white grease, WD-40 isn't the best for this application.
