I've had to rebuild the cylinders on my curbside slide which means I pulled them out the street side. They were a pain but doable and not much clearance at all. If memory serves I extended it and placed some blocking underneath in which to use my floor jack and porta-power to slightly raise the slide enough to slip the cylinder past the lower trim.
Good luck as they are far from a fun project.
Thanks for all the great information and youtube videos. As soon as I get past my current project I think I'll follow your guides and install guardian plates.
I have the same coach; 2003 Dynasty 42. And I'm hoping you can give me some advice on the slide-out hydraulics.
Have you had to get into yours?
Two of my cylinders are leaking. I'm having trouble removing the Road-side cylinders. They come out the Curb side, and there's not enough clearance for them to come out under the Curb-side slide.
Have you had occasion to pull yours out? Could you give me some pointers on how to jack up the Curb-side slide in order to gain enough clearance for the cylinders to eek out? I'm really hoping I don't have to cut the bottom of the slide for clearance.
I started a thread in the Monaco owner's forum this morning.
Thanks Walter McNeil
PS- I am incredibly jealous of your shop.
