Well the repack is done. They were pretty simple once I got into them. Its definately a two person job. It is very messy even when you blow the oil back into the tank. I guess we lost about 5 gal. of oil per jack. They were only single stage jacks so it went well. Take off the snapring and once the set screws on the head were out, just tap the head with a deadblow hammer and slide it down and hold it with a bungee while you take the snapring off the bottom and hoist plunger with a small rachet strap. Slide the head off and take to the tailgate and repack then assemble in reverse. No Problem.
