They can do it all or send parts. The teardown is a ball buster as the bolts are trapped and clearances tight. and one damn near impossible without some heavy torque. I know that the thing weighs a hunk but it may actually be worth considering shipping them all or part of the jack for thier replacement. Good people to talk with though.
