front jack seal replacement

[Firecapt176]

I have a leaking cylinder seal on my front jack, both of my front jacks will creep down after a few minutes of stowing. Are they replaceable, or do I have to get new hydraulic jacks in stalled?

You MIGHT find a Hydraulic Shop that can/will rebuild them. I doubt that you can do it as most of the jack cylinders are welded together and have to be cut apart in a certain way, rebuilt and then realigned and welded back together. If you have a lathe and can fabricate up a jig and trust your welding skills, go for it.

Here's 2 videos of the complete rebuild of a levelling jack:

Check with a hydraulic shop as you never know, it just might be a leaking check valve somewhere.

I was able to get it done at a hydraulic repair facility for $200
