Signs That A Control Arm Is Bad

The following are the symptoms to watch out for.

Vibrations

Worn control arm bushings cause the wheels to vibrate when you step on the gas pedal. Also, when taking a corner. The wheel shimmy may transmit all the

way to the steering wheel. Should you experience a trembling steering wheel, you may want to check the control arms to see if the bushings are worn. Other

car components can also cause the steering wheel to vibrate. Find out if they are responsible before confirming a damaged control arm.

Wandering Steering Wheel

Apart from the vibrations, bad control arms maker the steering wheel to move from side to side. Steering wandering could be a sign that the bushings or ball

joints are worn and moving too much. It takes driving comfort away and could also result in loss of vehicle control. Replacing the damaged parts of the

control arm is highly advised as soon as you experience this symptom.

Unusual Noises

Again, this sign indicates excessively control arm bushings and ball joints. Usually, bushings restrict the movement of a control arm. Ball joints, too, allowing

mostly rotation. Wear increases movement and causes the metal parts of these joints to knock. That results in sounds coming from the suspension,

especially when accelerating, goingaround a bend, or driving in rough road conditions.

Bad control arm noise can be a clunking, popping, or snapping, sound. It can also be a squeak when you bring the car to a halt. These noises are slight at

the beginning, and you may be tempted to ignore them at first. They will increase in intensity if you do not take action and reach a point where they openly

indicate badly damaged suspension parts.

Steering Wheel Pulling to the Side

Control arms allow efficient steering and the up/down movement of the car body. If faulty, they cannot serve that purpose as intended. You will experience the

car pull to one side while driving and have to use force to bring it back to course. While this may also be a sign of fault in other components, damaged control

arm parts could be the reason. Checking the control arms on either side would help you confirm the problem.

If the steering wheels feels too stiff at times, it could mean the ball joints are too dry. Lost lubrication would cause the control arm not to pivot freely, affecting

steering ease. It can bring drivability issues and even be a safety concern. This problem mainly affects the serviceable ball joints, especially when you have

forgotten to lube them. Unless the joints are badly worn and causing other symptoms, applying lubrication would restore their function.

Wobbly Wheels

Wobbly wheels can be a result of damage at the wheel hub but also due to bad control arms. In a vehicle, control arms attach the wheels to the chassis.

They must do so firmly, or the wheels will not rotate in a true plane. Bent control arms or those with worn ball joints and bushings will distort wheel alignment

and lead to a wobble. In addition to making affecting drivability, wobbly wheels can be unsafe at high speeds.

Sudden Change in Braking

As odd as it may be, bad control arms can make the brakes to assume sudden and unexpected improvement. It happens when bushings have worn and do

not allow for the back and forth oscillation of the control arm. The improvement is often only temporal, though, and does not occur every time you depress

the brake pedal. The erratic brake performance can be a drivability and safety concern if not checked. Immediate action would, therefore, be necessary if you

notice this symptom.

Uncomfortable Rides

Control arms are hinged on bushings that dampen vibrations and help to reduce the severity of bumps or rough terrain. The other end pivots on a ball joint

that smooths the wheel up and down movements. When these parts get damaged, passengers start to feel the potholes and bumps on the road.

Bad control arms will also cause a vehicle to lean too much at corners, especially sharp ones. When taking off from a stationary state, the rear of the vehicle

experiences a backward movement. If you notice these signs, it could be about time you installed new control arms.

Uneven Tire Wear

There are many causes of uneven tire wear. Bad control arms is one of them. Worn bushings and ball joints can throw the wheels out of alignment, causing

inner edges to wear excessively. 

Bent control arms, too. While damaged bushings and ball joints are easy to detect, a slight bend of the control arm would not be. It requires precise

measurements to be able to determine that.

A bad control arm may be as a result of damage to the parts it hinges on, or the control arm itself. It could be worn or broken bushings, bad ball joint(s), or a

bend. The symptoms listed here show that something may be wrong with the component.
