I have a 2017 39MB01 and my hydraulic piston on the passenger side slide out is leaking. Can that be rebuilt or do I need to replace it? If I need to replace it, how do I determine the correct replacement part?
replace the entire piston with a new one. its going to be less effort and less lost time. Chance are the piston has a rust pit on the shaft and that is the cause of the seal failing anyways. it should be one of these two.
