HWH leveling jacks

[Peggy & Ed McStay]

I just removed the rear jacks because of a leak on the right rear. i
removed both rear jacks because they both need to be rebuilt. got them
on the work bench and into the cleaning tank and gave them a good
cleaning.after removing and wiping them down i see no way to take them
apart. what am i overlooking here. has anyone taken these jacks apart
and rebuilt them. looks to me like the top end is welded and at the ram
end all i can see is the wiper. looks like a sealed unit.when HWH has
to rebuild them i guess they have to cut them open. any help and info
on this topic? thanks
