There is a casting you can buy from Lancair parts that "clips" around the lower end of the gear leg and provides a jack point for a floor jack. You'll also want this during condition inspections when you remove the wheels to repack the bearings. If you can't get one from Redmond let me know off list. I may know where an 'extra" is. The shimmy question has been explored, investigated, experimented on, photographed, argued over, and generally beaten by many on this list. Main gear leg movement is one of what, by my count, appears to be 3 possible causes. The others are loss of damping in the strut, and movement in the mount between the strut and the motor mount. I'm sure other people will soon jump in with all the other causes I've forgotten. I recommend joining the [Lancair_ES] list. Their archives should have more details on this ES issue. There are many who have worked this problem diligently who monitor this list, so standby for more advise.

Subject: [LML] Gear shimmy

After 250 shimmy free hou= rs, I am now getting gear shimmy when my ES-P slows down through about 30 kn= ots.  I think I recall folks saying this is due to looseness in the upp= er main gear leg sockets.  Is this correct, or is there another cause?&= nbsp; My strut (new version) looks fine.

If it is loose main gear, how do y= ou suggest that I get the main gear off of the ground?  There are no ob= vious jack points.
