I figured it best to deconstruct my nose gear to bird-dog the problem from the ground up. I removed the wheel and raised the nose gear off of the ground using an eye bolt in the floor of my hanger. First off, I am getting a new front tire that I will balance before I install it. But as I moved up the gear leg, I noticed that there is about 1/16" of play in my gear leg in the horizontal axis. This translates to 1/4"of play at the nose wheel. There were quite a few posts about under sized bushings in the gear leg attach point a few years ago, but this is NOT the problem. My gear leg bushings are nice and tight to the ears of the gear leg. The problem is that the "ears" are too far from the "hole" on the engine mount. Could this be the problem that is causing my shimmy? Is there a remedy or should I just forget it, and why did this not cause a problem before. Has anyone else encountered this issue and how did you resolve it? -------- See you OSH '18 Q/B - flying 8 yrs.

That's about the time when they start to compress. Marcus > On Sep 23, 2017, at 9:30 AM, AirMike wrote: > > > I just started getting some severe nose gear shimmy after 400 hours of flying.

I'm getting ready to dig into mine a bit more because I suspect a similar issue. Going over a bump or lowering the nose to the runway usually results in a pretty good thump and my ears tell me there's some slack somewhere in the system that I need to find. Regarding the ears, is it possible to ship the gap with washers so the ears fit tight? Haven't looked at mine yet.
