We just had ours fixed. mobile rv man took cylinder off for us and we took it to a hydraulic shop to be reworked. it cost $119.00. Mobile rv man put it back on and it works perfectly. Large slide now works like it was brand new!!! The trick is to take the cylinder to a hydraulic shop for repairs. We tried three different repairs guys before we made the right choice!
