Well besides getting dirty lying under my rig the jack really wasn't to difficult to take off. Six 3/4" nuts and bolts that I sprayed with penetrating oil first and let sit for several minutes. I used a 1/2" ratchet and socket with a two foot pipe for extra leverage. No problem at all. Three hydraulic lines came off easily with a 11/16" open end wrench. I used a hydraulic car jack under the RV jack to support it when taking out the bolts. I thought the jack would weight 50-60 lbs. but it was surprisingly light. That I found is what caused the fluid loss or "blow out". The jack body is made of extruded aluminum. The seals didn't blow but the jack body cracked along its entire length. There are three bolts that hold the caps on the top and bottom of the cylinder holding the hydraulic ram. Though these bolts do not run the length of the cylinder, the bolt holes so to speak do run the length of the cylinder and the cylinder blew out along its entire length! Hydraulic shop was amazed to see this but wasn't surprised it happened because of the wall thickness where the cylinder and bolt holes meet is thin. $429 plus ship and tax from Lippert Components, but, of course they are out of stock! Plugged the three hydraulic lines with screw in caps, they do leak a bit, and plan on having our final camping outing for three days this weekend minus the use of leveling jacks. If need be we'll level the rig like the tow behind crowd using boards under the wheels. The wonderful world of RV'ing.
