Steering Systems
The steering system works with the suspension system to provide directional control with a comfortable amount of steering effort. It must do this while allowing for the necessary movement in the vehicle??? suspension system. Some parts serve both systems. The steering system consists of a steering gear, steering linkage, a steering column and a steering wheel. Two types of steering systems are widely used in today's vehicles: "rack-and-pinion" steering and "conventional" steering.

Typical Pitman Arm Replacement Guideline
Some pitman arms contain a ball socket joint on the outer end. The threaded extension on this ball socket fits into the center link. On other steering linkages, the ball socket joint is in the center link, and the threaded extension fits into the pitman arm opening. If the pitman arm is bent, it must be replaced because the tie-rod is not parallel to the lower control arm. Under this condition, excessive front wheel toe change occurs on road irregularities, and front tire wear may be excessive.
The following is a typical pitman arm replacement procedure
(1).Position the front wheels straight ahead, and remove the cotter pin and nut from the ball socket joint on the outer end of the pitman arm.
(2).Remove the ball socket extension from the pitman arm or center link with a tie-rod end puller.
(3).Loosen the pitman-arm-to-pitman-shaft nut.
(4).Use a puller to pull the pitman arm loose on the shaft.
(5).Remove the nut, lock washer, and pitman arm.
(6).Check the pitman shaft splines. If the splines are damaged or twisted, the shaft must be replaced.
(7).Reverse steps 1 through 5 to install the pitman arm. The pitman arm-to-shaft nut and the ball socket extension nut must be tightened to the manufacturer's specified torque. Be sure the pitman arm is installed in the correct position on the shaft splines. Install the cotter pin in the ball socket extension.
Typical Idler Arm Replacement Guideline
The idler arm adjustment is very important. If this adjustment is incorrect, front wheel toe is affected. After idler arm replacement, the front wheel toe should be checked.
(1).Remove the idler-arm-to-center-link cotter pin and nut.
(2).Remove the center link from the idler arm.
(3).Remove the idler arm bracket mounting bolts, and remove the idler arm.
(4).If the idler arm has a steel bushing, thread the bracket into the idler arm bushing until the specified clearance is obtained between the center of the lower bracket bolt hole and the upper idler arm surface.
(5).Install the idler arm bracket to frame bolts, and tighten the bolts to the specified torque. Be sure that lock washers are installed on the bolts.
(6).Install the center link into the idler arm, and tighten the mounting nut to the specified torque. Install the cotter pin in the nut.
(7).If the idler arm contains a grease fitting, lubricate as required.
Considering how important the pitman arm is to control over the vehicle, it is essential that you know a few signs and symptoms to look for that indicate unusual wear or impending failure. These signs include
1.Grease around the boot at the end of the pitman arm
2.Your steering feels abnormal, or that it's slipping
3.There's too much play in the steering wheel
4.The steering feels like it's wandering
(5).What is the result when pitman arm fails?
The result is that you run the very real risk of losing steering control due to pitman arm failure. When the pitman arm fails, there is no longer a connection between the sector shaft and the wheels. When that direct connection is lost, you lose the ability to steer, which can result in dangerous consequences.
(6).What is the symptom when idler arm wears out?
A worn and loose idler arm results in excessive freeplay of the steering linkage. It makes the vehicle wander on the road. If you experience any of the symptoms mentioned above, you may need to replace your idler arm to prevent possible damage to your car's steering system.
(7).How to diagnose a bad idler arm?
To diagnose a bad idler arm you only have to observe the connections as the wheels are turned. Observe the connection at the end of the idler arm, where the shaft is set into the bushing near the wheel. Use the flashlight if necessary. If the shaft of the idler arm moves in any direction, prior to the wheel beginning to turn, the bushing is bad and the idler arm needs to be replaced.
(8).Road Walking
Also known as road wandering, this scary phenomenon occurs when a vehicle seems to wander or weave back and forth on its own. If you are being attentive and steady on the steering wheel but are experiencing road walking, it will be genuinely difficult for you to keep the vehicle straight.
(9).Play In The Wheel
If you have suspicions that the idler arm is in poor condition, this symptom can be tested under safer and easier conditions than road walking. While the vehicle is sitting still, try moving the steering wheel. If you can move the wheel considerably from side to side without much resistance, your steering wheel has too much play.
While you certainly don't want your car to be unresponsive when you make steering maneuvers, a wheel that has too little resistance is also bad and a sign of idler arm problems.
(10).Free Wheeling
This symptom can only be observed and tested in a garage or mechanic setting, as the car must be raised so that the front wheels are suspended off of the ground.
Always use suggested and available safety equipment when working underneath a vehicle.
While the vehicle is raised, go to your front wheels and without manipulating the steering wheel at all, see if it's possible to move the front wheels from side to side. If the wheels do shift back and forth, it's a sign that you should look into the idler arm.
Frequently Asked Questions
(1).What is the pitman arm all about?
Not the sexiest of all automotive parts, the pitman arm, named after railroad engineer George Pitman, is tasked with steering your car. The pitman takes the circular motion generated by the sector shaft and converts it so that it can be used to turn the wheels. The pitman arm, supported by the sector arm, is attached directly to the steering gearbox.
(2).How long does a pitman arm last?
The most common type of wear and tear for the pitman arm is actually to the ball socket located at the end of the arm. Like all other ball joints, this one will eventually wear out and need to be replaced. Regular lubrication can prolong its life, though. The pitman arm and other front end components should be lubricated at every service (oil change) and should be inspected regularly to prevent these problems from becoming severe.
(3).Why should I get my pitman arm inspected on a regular basis?
The pitman arm needs regular maintenance. If it receives that maintenance, it will easily last the life of your car. However, if you fail to give it regular maintenance, you will find that between 30,000 and 50,000 miles, your car's steering will falter. To prevent this, vehicle owners should have their pitman arm inspected regularly. However, if you drive in rough, rocky, off-road or other harsh conditions, the pitman arm will deteriorate quickly.
