  Q: How to inspect the Center Link,Idler Arm,Pitman Arm and Tie Rod?

  A: The inspection process for the steering linkage involves checking the various components that connect the steering gear to the front wheels. This includes the Pitman arm, idler arm, relay rod, tie-rods, and steering damper. The wheels should be set in the straight-ahead position and the steering wheel locked before raising one side of the vehicle. A dial indicator is used to measure any play in the steering system, which should be less than 0.108 inches. The idler arm should also be checked for excessive play, with a measurement greater than 1/4-inch indicating the need for replacement. Additionally, torn ball stud boots, frozen joints, and bent or damaged linkage components should be inspected. The removal and installation process for the tie-rod involves loosening the wheel lug nuts, raising the vehicle, and removing the wheel. The cotter pin is then removed and the castellated nut loosened. Depending on whether the outer or inner tie-rod end or the entire tie-rod is being replaced, the appropriate steps are followed. Lubrication and adjustment of the tie-rod end is necessary before reinstallation. The idler arm can be removed by loosening the nut and using a two-jaw puller to separate it from the relay rod. The idler arm-to-frame bolts are then removed. Installation involves positioning the idler arm on the frame, tightening the bolts, and inserting the ball stud into the relay rod. The relay rod can be removed by separating the inner tie-rod ends and disconnecting it from the Pitman arm and idler arm. Installation is the reverse of removal. The Pitman arm is removed by separating it from the relay rod using a puller, removing the steering gear, and then removing the Pitman arm nut and washer. The Pitman arm is then removed with a puller. The steering damper can be inspected for fluid leakage, wear on the bushing, and tested for smooth resistance. Removal involves disconnecting it from the relay rod and removing the mounting bolt and nut. Installation is the reverse of removal.
