Idler Arm Bushings
I did this just last week. The heat shield comes off easily with 1 hex head screw (10 mm I think). I changed the drag link and both tie rods at the same time but I think you can change the bushings without removing the othe pieces. Just push them out of the way. Be sure to use some syl-glide when reassembling the bushings. I used the old bolt and a couple of box end wrenches to fashion a puller to lever the bushings in.
