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.
Picture(A)
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).Do I need to replace the control arm if the bushings are worn?
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.
Ball Joint Preventive Maintenance:
Some ball joints use zerk grease fittings, which allow for periodic lubrication of the moving ball and stationary socket inside the ball joint. Grease fittings can sometimes be found on other suspension components and need to be lubricated as part of a preventive maintenance program provided by the OEM.
Loaded Upper Ball Joint Play Measurement:
The most common problem in the suspension system is play, or looseness of the parts. Although many of the parts are designed with special connections that allow for movement to accommodate movement of the wheels, excessive play is actually a bad thing. Excessive play magnifies the feel of road imperfections and makes the steering less responsive to steering wheel input. Excessive play is potentially very damaging, as it causes wear on the connecting parts and tires. Naturally, any amount of play in a fixed part is problematic and is frequently a result of part failure. Remember, unwanted looseness in the suspension system can be extremely dangerous and should be corrected as soon as possible.
Picture(A)
1.Obtain a properly sized block of wood to fit between the upper control arm and the frame.
2.Place the block of wood between the upper control arm and frame so that it is secure.
Picture(B)
3.Raise the vehicle by lifting the body, using the specified lift points, so that the tire is a few inches off the ground. Support the body with a jack stand.
4.Place a dial indicator on the upper control arm and vertically against the steering knuckle.
5.Place a pry bar under the tire, and pry it upward, watching the dial indicator reading as you pry and release. Record the total amount of movement in the joint, and compare to the OEM specifications.

6.Rock the bottom of the tire in and out, watching for play in the lower ball joint, and compare to OEM specifications.
Loaded Lower Ball Joint Play Measurement:
1.Jack up the vehicle, place safety stands under the control arms, and look up the exact procedure in the online service information.
2.Place a dial indicator on the lower control arm and vertically against the steering knuckle.
3.Place a pry bar under the tire and pry it upward, watching the dial indicator reading as you pry and release. Record the total amount of movement in the joint, and compare to the OEM specifications.
4.Rock the top of the tire in and out, watching for any play in the upper ball joint specifications.
Frequently Asked Questions
(1).What happens if a ball joint breaks?
When a ball joint breaks, you will hear a mysterious noise inside your car wheel.
Your car tire will wear-out since your alignment will be broken, and you will feel the car getting out of control.
If the ball joint breaks completely, it can be separated, and things can turn sour quickly. The wheel will stop being nice and can even steer you off the road. It can be serious.
Broken ball joints will seriously affect the steering and suspension. It can even result in your wheel falling off the car.
(2).What happens if I don't replace ball joints?
If you don't want to replace your ball joints, then get ready to experience some serious issues. The old ball joints cause mysterious clunking noise or drifting steering. Once they are worn-out, it will seriously affect your steering and suspension. However, you do not need to change the ball joints if it is new.
(3).Do I need to grease new ball joints?
I would say it will be a wise decision if you grease your new ball joints. At least I will always grease a new one after the installation. Greasing a new ball joint will make it stronger and extend its lifetime because there is a minimal amount of grease inside. I suggest you do so after the first installation. Follow the instruction card.
