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.

  A dynamic or a comfortable driving style? The control arms are individually adjusted to the vehicle depending on the desired characteristics. They also absorb lateral movements and forces resulting from driving off and braking.

Control Arm Bushing Replacement Reference:

  Control arms themselves do not generally wear out, but the control arm bushings and ball joints do, so you will likely need to remove them to service those components. Yet, some OEMs or parts suppliers do not sell bushings and ball joints separately, so you may have to purchase the entire control arm and replace it as a unit. Also, control arms can become bent or damaged as the result of a collision or driving through a deep pothole, so control arms do need to be inspected for damage. Many control arms are now made from forged or sintered aluminum, so you may need to measure for damage or check it on an alignment machine.

1.Remove the coil spring and steering knuckle by following the steps in previous skill drills.
2.Loosen the bolts holding the upper control arm in place. Note that there might be shim packs held in by the bolts. If so, tape them together in their packs, and label their positions.

3.Remove the lower control arm by removing the bolts holding it in place. As you dismantle the system components, carry out a constant inspection of the parts being removed. Doing so will aid you when you need to order replacement parts. You should also mark mating parts with white paint to aid in reassembly.

4.Inspect the upper and lower control arm for wear or damage. If the control arm bushings show signs of excessive wear or deterioration of the bushing material, they will have to be replaced.
5.Replace the worn bushings in the upper and/or lower control arm. Replacement of control arm bushings can be performed two ways — with a hydraulic press with correctly sized press tools or with an air chisel. Be careful using an air chisel: Damage to the control arm can result, such as gouging the mounting surface of the bushing if you slip with the chisel.

6.Press method: Place the control arm in a hydraulic press supported so the bushing is level to the press head. Using the correct-sized adapter, press the bushing out.

Picture(E)
7.Using the press, install the new bushing into the control arm. Be careful to start the bushing in straight, or you could bend the control arm. Press it in until the flange bottoms out.

Picture(F)
8.Air chisel method: Install the control arm in a vise. Use an air chisel to work the bushing out. Be careful not to gouge the mating surface of the control arm.

9.Using the air hammer, drive the new bushing into place, making sure it is fully seated.

Frequently Asked Questions

(1).What is a control arm and how does it work?
  A control arm is a suspension component, usually made of heavy gauge steel or aluminum, that links the steering knuckle in the front — or axle carrier in the rear — to the frame of the vehicle. Many vehicles have upper and lower control arms. The inboard link(s) of the arm securely bolt to the frame of the vehicle through rubber bushings, while the outboard link of the control arm connects to the steering knuckle through a ball joint; all of which allow the control of the up and down movement of the steering knuckle or axle carrier. This minimizes the transmission of shock and vibration to the vehicle's body.

(2).When to consider replacing a control arm?
  The structural portion of the control arm can last the life of the vehicle — except for cases of corrosion or crash damage. However, the rubber bushings and the ball joint in a control arm have a limited life. A mechanic should investigate if you notice:
  Wheel alignment difficulties. Should the bushings, or the ball joint, in a control arm be worn, it will be impossible to properly align the vehicle. The worn components, or the entire arm, must be replaced.
  Vehicle won't track straight or pulls to one side. A car will not track straight and may require constant steering correction if there is a worn, bent, or loose control arm.
  Clunking or squeaking noise. A loose control arm, or a control arm with dried out, rotted, or loose bushings, may move enough to cause detectable noise from the suspension as you go over bumps in the road.
  Vehicle pulls to one side only when braking. Worn bushings or ball joints can allow control arm to shift when braking, causing the vehicle to pull to one side. Although, this could also be caused by brake calipers.

(3).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.

(4).Is it safe to drive with a control arm problem?
  No. If the car wanders on the road, pulls to one side, or noise from the suspension is loud, you need to schedule repair right away. Should the problem be limited to low levels of noise, such as clunking or squeaking, continued use of the car is reasonable until you can schedule a repair. Should the control arms be damaged as a result of a collision, it would be unsafe to drive the car until it is repaired.

(5).Attentions
  The number of control arm types vary from vehicle to vehicle depending on the design of the vehicle suspension.
  Control arms should be replaced in pairs — arms on both sides of a front or rear axle — if the reason for replacement is worn control arm bushings or a worn ball joint.
  All other suspension components should be inspected when control arms are replaced because looseness, damage, or excessive wear in other parts of the suspension system will make it impossible to perform a wheel alignment after the control arms are replaced.
