Nice Video. This illustrates the problem better than words can describe it. You are experiencing nose wheel shimmy. I would check from the tire toward the back the following items. 1. Tire itself (no flat spots?), wheel bearing not overly loose or worn? The single bearing wheel should feel a little loose, that is ok, but if you can move the tire by an inch to the left or right, that is not ok. 2. Nut cracker linkages. The bolts should be tight enough to not allow for any play. If the bolts are tight and you are experiencing still play in the linkages, check the bushings, they might be worn, - use new bolts. 3. steering collar of the strut. You should no be able to move the collar up and down on the strut. There are shims for adjustments. 4. The steering socket ball. . Best is to have it replaced . (see also http://www.ercoupe.info/?n=Main.Steering) 5. check for looseness of the steering rod in the steering column. Sometimes the lower bushing of the steering column is worn .- this feels like extra play in the Heim bearing of the steering rod. It is either way, or both. (http://www.ercoupe.info/?n=Main.PushRodBearings) Everything within the steering should be working smooth but without any click clack play. Best to check is it either by lowering the tail with weights or a helper and rocking the linkages back and forth, or by having a helper putting slight pressure on the controls inside the plane , while you are watching and feeling. The helper should just gently go back and forth with the controls. Little is a lot here. The nose is this time on the ground.

I flew this landing with 17 to 18 lbs in the nose tire. As you can see I landed on the mains, set down on the nose, rolled 300 to 400 feet and then it almost felt like it was going to break off until I got to about 15mph.
