If the hydraulic cylinder is for a slide out the ends of the unit are welded on and IMO you can't rebuild those...

If however your issue is with a LG or leveler then those can be rebuilt... the issue at hand will be finding the seals you need...

A good hydraulic shop will be able to rebuild the LG and leveler leg cylinders for less than $200 which is considerably less cost...

The info on the Montana FB group shows a LG leg torn apart and the inner seals, etc...

However... all that is USELESS because the OP has never taken the time to indicate the PN for each of the seals that were replaced...

Images attached are the seals inside a Lippert leveler leg... as shown on the FB page... the blue seal IS usually the culprit... the outer seal located on the bottom of the leveler and LG leg is merely a wiper seal and has no function in fluid and pressure retention
