The inspection process for the steering linkage involves checking the components that connect the steering gear to the front wheels, such as 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.

To remove the idler arm, start by loosening the nut and using a two-jaw puller to separate it from the relay rod. Then, remove the idler arm-to-frame bolts. For installation, position the idler arm on the frame, tighten the bolts, and insert the ball stud into the relay rod.

To remove the Pitman arm, use a puller to separate it from the relay rod, remove the steering gear, and then remove the Pitman arm nut and washer. The Pitman arm can then be removed with a puller. For installation, reverse the removal process.

To inspect the steering damper, check for fluid leakage, wear on the bushing, and test for smooth resistance. To remove it, disconnect it from the relay rod and remove the mounting bolt and nut. For installation, reverse the removal process.
