You are probably talking about the idler arm bushings from the description of where it is located. You have to take the nut off the bottom of the bolt and take the bushings out with the arm still in place. When you do this you will have enough room to snake it out. Reinstall in the same fashon. Load the bolt into the idler arm and place the top bushing onto the bolt as well. Now put it in place and use the bolt to pull it in.
