Suspension Control Arm 

• Control arms are installed in pairs on the front and rear axle and connect the chassis to the wheels as part of the suspension. Therefore, they have a significant influence on the driving characteristics of the vehicle.

Tie-Rod End

  The tie-rod assemblies connect the center link to the steering arms, which are bolted to the front steering knuckles. In some front suspensions, the steering arms are part of the steering knuckle; in other front suspension systems, the steering arms are bolted to the knuckle. A ball socket is mounted on the inner end to each tie-rod, and a tapered stud on this socket is mounted in a center link opening. A castellated nut and cotter pin retain the tie-rods to the center link. A threaded sleeve is mounted on the outer end of each tie-rod, and a tie-rod end is threaded into the outer end of this sleeve.

Outer Tie-Rod End

  Some outer tie-rod ends have a ball stud that is surrounded by an upper hardened steel bearing and a high-strength polymer lower bearing seat. The hardened steel upper bearing provides strength and durability, and the polymer lower bearing seat provides smooth rotation of the ball stud in the tie-rod end. An internal spring between the polymer lower bearing seat supplies self-adjusting action and constant tension on this seat. A seal in the upper part of the ball joint housing seals the ball stud to prevent contaminants from entering the tie-rod end. These tie-rod ends are installed on some original equipment manufacturer’s vehicles, and they are available as replacement tie-rod ends on most vehicles.

Inner Tie-Rod End

  Some inner tie-rod ends contain a bolt and bushing. These tie-rod ends are threaded onto the rack. Since the rack is connected directly to the tie-rods, the rack replaces the center link in a parallelogram steering linkage.
  Some inner tie-rod ends have a mirror-finished ball and a high-strength polymer bearing to ensure low torque, minimal friction, and extended life. A hardened alloy steel rod extends from the ball to the outer tie-rod end and provides maximum strength and durability.

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's 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.

Frequently Asked Questions

    1.What's the function of control arm?

• The control arm connects the hub and the frame of the car. There are ball joints on the hub side and bushings on the frame side to achieve up and down instead of forward and rearward.

    2.What is the significance of the control arm for the car?

• As an important part of the car suspension, the control arm is used to transmit the required supporting force of the wheel and to withstand all the front and rear direction stresses. It is an important safety part of the chassis system. Therefore, it requires high strength and reliability in the design. Its fatigue strength is directly related to the safety of vehicles and members.

    3.How to tell the quality of control arm?

• Look at the materials and processing of the control arm: the materials used to control the arm, common are steel and aluminum alloy. In ordinary family cars, steel control arms are very common, and the basic appeal is to meet the strength while controlling costs. In the middle and high-end models, you will see the control arm of the aluminum alloy and the wheel bearing housing. In addition to meeting the strength of the suspension, this material can further reduce the weight and reduce the weight of the suspension spring to improve the suspension response. Improve driving performance.
• Look at chassis protection and workmanship: Regarding chassis protection, we mainly pay attention to whether it is equipped with engine under guard, whether there is coating or cover at the bottom of the car body, whether the oil pipe is covered with a guard plate, whether the front and rear wheel arches are protected. Board or coating coverage, etc.

    4.Do I need to replace the control arm if the bushings are worn? What is the safety risk?

• Because the weight of the car is transferred through the control arm two rubber bushings are fitted at the pivot point and bolted to the frame. Road conditions and driving habits can contribute to the wear of these bushings which will become worn and fall apart. These bushing can be inspected by raising the car up and looking for an irregular configuration of the rubber center of the bushing. Many control arms have the ball joint manufactured into the arm which will be replaced along with the control arm itself. When one control arm is worn it is highly advised to replace the opposing arm.

    5.What is the average cost of replacing control arms?

• The cost to replace control arms depend on the vehicle. Control arms cost different amounts depending on the vehicle, as well as the labor to install. Some are easy to install and take little time, while others can take several hours.

?

    6.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.

     7.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.

     8.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.

    9.What common symptoms indicate pitman arm needs to be replaced?

• 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

    10.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.

    11.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.

    12.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.

    13.When to replace tie rod ends?

• Tie rods can last for years and years and some car owners may never have to replace them at all, but their longevity can be affected by certain driving conditions. Driving obstacles like potholes, poor road conditions or even minor accidents can cause tie rods to work incorrectly. Because of their importance and high usage, some people recommend having the tie rods inspected regularly.

    14.Why should I get my tie rods inspected on a regular basis?

• If you don't get your tie rods inspected on a regular basis, there are some warning signs to watch (and listen) for. If your vehicle pulls to one side while driving, or when braking, it's possible that bad tie rods may be the culprit. Your vehicle's tires will also show uneven wear on the inside and outside edge of the tire when there's a tire rod issue. However, one of the most noticeable signs of tie rods going bad will be a knocking sound coming from the front end of the vehicle when you turn into a parking space, or some other low speed, tight turning situation.

    15.What are the symptoms of a bad sway bar?

• Some of the common symptoms of a bad sway bar bushing or sway bar links going bad are: clunking noise, rattling noise, knocking uneven noise road, lack of stability when driving and noise going over speed bumps. poor handling during turns.

    16.What happens when a sway bar breaks?

• Because a sway bar helps the car's suspension to put more pressure on loaded springs, a broken sway bar means that the car's suspension will not be able to handle corners as well or as quickly. While it is possible to drive with a broken sway bar, as a precaution do not take corners with excessive speeds.
