The required tools for Pitman Arm servicing and repairing consist of the Pitman Arm puller (J 29107-A). Start the service procedure by lifting the vehicle while also taking off the tire and wheel assembly. First remove the power steering gear but keep the Pitman Arm retaining nut along with washer for future assembly so mark both components for correct alignment. The damage to the Pitman Arm, Pitman Arm shaft or puller will occur when you strike them with a hammer. The Pitman Arm puller (J 29107-A) needs to be used to take out the Pitman Arm before checking the ball stud threads for fractures alongside inspecting the ball stud seals for signs of damage due to wear. The threads of ball stud require cleaning before applying the ball stud nut. After aligning the installation marks from removal on the Pitman Arm to the pitman shaft position you should place the washer and Pitman Arm retaining nut before tightening it to 250 nm (185 ft. Lbs.). The power steering gear should be reinstalled followed by lowering the vehicle.

The first step to fix the Pitman Arm requires vehicle elevation. Sever the prevailing torque nut from connecting rod ball stud of the Pitman Arm before throwing it away. The universal steering linkage puller (J 24319-B) allows users to separate the connecting rod from the Pitman Arm and the vehicle should be set down afterward. The power steering gear and prevailing torque nut with washer must be taken off from the steering gear shaft before discarding the prevailing torque nut. Label the Pitman Arm together with the pitman shaft for assembly alignment purposes but abstain from hitting the Pitman Arm and Pitman Arm shaft or puller since this could cause damage. The service specialist should utilize the Pitman Arm puller (J 29107-A) to detach the Pitman Arm for ball stud thread and seal examination to check for damage or signs of excessive wear. You should cleanse and prepare the threads of both the ball stud and the ball stud nut. During reassembly process align the marks which were initially made to the Pitman Arm during its removal before installing it onto the pitman shaft. The installation requires a new prevailing torque nut coupled with the washer before applying a torque of 250 nm (185 ft. Lbs.). Reinstall the power steering gear before raising the vehicle once again. Complete the installation by using the steering linkage installer (J 29193) on the connecting rod ball stud to attach it to the Pitman Arm. Maintain the seal on the stud and tighten it to 54 nm (40 ft. Lbs.) for taper seating. Use the new prevailing torque nut to tighten the connecting rod ball stud at the Pitman Arm up to 62 nm (48 ft. Lbs.) after mounting it while parking the vehicle.

Install a new prevailing torque nut on the idler arm ball stud and tighten it to 47 Nm (35 ft. lbs.).

Reinstall the power steering gear and lower the vehicle.

Remove and discard the prevailing torque nut from the idler arm ball stud.

Use the Steering Linkage Installer (12 mm) (J 29193) to install the relay rod to the idler arm ball stud, ensuring the seal is on the stud, and tighten to 54 Nm (40 ft. lbs.) to seat the tapers.
