Thanks. I got them out. If I had known the amount of effort it would have taken, I probably wouldn't have done it, but the steering is much better now. Well worth it.
Is there a torque spec. for that idler arm bolt? I tightened it about as much as I could without putting a 3 ft bar on the wrench. Are there serious safety issues if that bolt loosens? I am planning on driving it for a few days and then re-tightening that bolt.
