stupid idler arm

Bingo, you beat me to it. The idler arm has two steel washers, one on top one on the bottom. All the space has to be taken up between the two tabs sticking out of your k-member. The nut and bolt will then tighten up and there will be no up and down movement of the idler arm.

No, depends on the design. The Moog one I have has the bearing per se is not dependent on separate washers. Once you clamp the center tube into the mount with the through bolt, "it's tight." The foam washers, on the Moog one, merely seal the grease on the ends of idler.

So you must be careful. I "had" one with nylon, and it was a real poor deal. It appeared to me that the hole deal clamped between the K member and acutally TURNED within the K member which would cause wear on the K itself. The Moog design does NOT do this. The extended central tube in the Moog one is clamped into the K, and does not move.
