Steering wheel/front vibrate when braking at highway speed

Video of the slop in the idler arm. I'm pushing the wheel left and right in this video.



The fit between the bolt and the idler arm should be really snug I guess? It seems the bolt might have some wear because there is some play there too. I installed the idler arm with the washers that came with it. One on top and one in the bottom. I could probably fit another washer in there because the idler arm travels up and down a bit between the "jaws" of the k-member.
