Isaac is sooooooo right about the idler arm. Even with a brace, I bent them. It is best to always have a spare because it doesn't take much to tweek them. I bent one just pulling a bush out of the back yard! I finally gave up wheeling my truck. Best way I found to keep it from bending is to leave it in 2WD!
Get a couple of lifetime warranted ones from Auto Zone. They typically have them in stock. Pay once and don't worry about it. They are pretty easy to replace.
