I need to replace my idler arm and am wondering what special tools I may need. It looks like a pretty easy job. Any helpful suggestions are appreciated!

 

It took me about 2 hrs and didn't lose any blood. I think it was a 18mm socket for the bolts on the frame and I borrowed a Idler arm/ball joint puller/clamp type tool from AutoZone. I can't remember the exact name of the tool, they had like a placemat on the counter with the picture of several tools labeled for certain jobs making it easy to pick the one you need. Be sure to adjust the Idler arm height position on the frame so the center link is level. This will take some trial and error. I got my idler arm from Autozone for like $35 with lifetime Warr. The factory Idler arm looked pretty weak even next to the lower cost Autozone replacement.
