Pappascott
The cylinder is held in place with 1 bolt to the body and 1 bolt to the RAM head, 2 split pins on the guide rods and the hydraulic line.
Easily done with the trlr up and braced for safety. Just messy and dirty.
About 1-2 hour off, same to install.
But you do have to crawl under the lifted trlr to accomplish. Once you look at it, it will make sense. Do a SEARCH for more detailed info.
