It feels strange to land and wait for the big shake, both wheels dancing synchronized back and forward https://youtu.be/p0zAVvPMCIg, and nothing happens. The whole ground operation feels so much better and stable. Two gas springs dampers for less than 120$ did the trick. Stumbled over another method that works 75%, put =BD a gallon of water in the rear compartment of the wheel fairing. Does little for light vibrations but sure does cure the big shakeouts by counter phase movement of the water. All other things such as: tire pressure , balancing, rotating tires, new tires, reinforcement of the legs, adjusting camber- toe angle by elongating cross holes, where tried in every amount and combination with only temporarily small improvements. I still do not understand why the problem did start after two years of flying and not @ the beginning. Somehow over time there was a loss of damping in the system. Now I finally can ship several parts of my avionics that did not survive the shaking for repair and modify the gear leg fairings.
