After 250 shimmy free hours, I am now getting gear shimmy when my ES-P slows down through about 30 knots.  I think I recall folks saying this is due to looseness in the upper main gear leg sockets.  Is this correct, or is there another cause?  My strut (new version) looks fine.

If it is loose main gear, how do you suggest that I get the main gear off of the ground?  There are no obvious jack points.

Thanks for the advice!
