No pics. I did not undo the bolts retaining the legs and they are still safety wired.  But I could see movement in the socket ever so slightly but that movement translates to a large movement at the gear.

So I think a shim kit will be necessary.

Yikes!!!
 
The gear legs should be real snug in the attach brackets.  The bolt should be safety wired as well.  Does it look like it has been wiggling for a while? Are the holes elongated at all?   I have not seen the shim kit, but from what I have read, it is thin shims to really snug up the leg in the bracket, not to take up 3/16” of play.
 
Have any pics to post??
 
Good luck.  Maybe Ron will chime in with some ideas.

Got the plane jacked up ok. Found that on the. Right side I had 3/16" vertical movement of the landing gear leg. About same on other side. 
 
Is this ok?  The shimmy was so bad I sheared off one of the front fairing side retaining screws.

If you have removable fairings for the main gear attach points, you can use a standard floor jack or AC jack at the gear attach point.  Just use a piece of wood or something solid for support.

All,
 
Got a pretty shimmy tonight, enough to loosen the front wheel fairings screws.  Also while pushing her back into the hangar I could hear a rubbing sound on the left main wheel, but only pulling forward; not backing.  So now its time to jack up the main gear and see whats going on.
 
I tried to search the archives to see how best to support the wings.  No luck.
 
I am going to purchase a floor jack and lift the main gear one at a time using the Lancair adapter.  Then put a saw horse with carpet and foam to hold the wing while I check the main gear for play in the legs.  I suspect I may need shims or be having wheel bearing problems.  
 
I remember reading but I don’t recall where to put the support under the wing.  Unfortunately, I don’t have jackpoints.
 
Any advice?  Thank you
 
George
