Help with idler arm

Sometimes you have to spread the 'ears' of the k-frame apart to fit the new idler arm in. They get bent inwards when the bolt and nut is tightened.

Take a large crescent wrench and turn it down so it fits over an ear of the k-frame where the idler arm goes, and then use it to pry the ears apart. This will make it easier to put in the new idler and washers. The ears will come back when you torque the bolt and nut for the new one.
