I noticed when I had my truck off the ground the other day I had some play in my idler arm so I pulled it off today and rebuilt it. It cost $4 for the new bushings and it only takes about 30 minutes to do. My truck drives alot better now with that piece solid. I also added a Downey brace. I highly recommend rebuilding that sucker if you have alot of miles on yours you WILL notice it. Too easy to not do.
