W124 Idler arm bushing importance....

[JohnM.]

How much would a bad idler arm bushing affect steering? I replaced all the tie rods, drag link, and dampener. Also threw on a Sportline front sway bar w/ new bushings. Steering is much improved, especially on turn-in. Fresh alignment and it drives great in general.

However, I am still having "nervous" on-center steering, tramlining, etc. To a less degree than I was before all the work, but still I have to fight to keep it on center, very annoying. Idler arm bushing?
