What Is the Function of the Lower Control Arm?

The control arm, also known as the A-arm, is a segment that joins the tire and the suspension to the frame. Older vehicles might have an upper control arm, while most of the recent models have a lower control arm.

The lower control arm, also ensures that you have a smooth ride. The wheels are joined to your vehicle by this control arm, which goes down and up when driving, to maintain the wheels well on the pavement.

Whenever you are driving down the road, you can observe that you do not feel all the bumps you might come across. This is because your lower control arm absorbs these irregularities.

The control arm is connected through 3 mounting points and another ball joint that joins the 2 bushings and the wheel to its frame.

The flexible two rubber control arm bushing lets your lower control arm flex, allowing the wheel to move about as it should when driving over bumps on the road. This is an important part of the suspension system, so it is necessary to change your lower control arm immediately after the problem happens.

What Are the Symptoms of a Bad Lower Control Arm?

Fortunately, some symptoms would let you know you need to replace the control arm, as soon as possible. The signs include:

  • Uneven tire wear.
  • Braking problems.
  • Noise when you come across bumps during driving.
  • Issues with the steering.

Some signs to watch out for are:

Poor Steering Wheel Alignment

The ball joint can wear down over time, which could affect your tire’s alignment since it joins the lower control arm to the tires. So when the tires are not moving as they should, you’ll know that the alignment is off, whenever you turn the steering wheel.

Even though it might not be serious at first, it could get serious as the joints continue to wear down.

Sounds as You Drive Over Bumps

The suspension system is accountable for mitigating bumps you come across when driving on the road. So, when the lower control arm calls for a repair as you drive, it can begin to move about, and in addition to the sounds, you’ll be able to notice it on time.

The sound would be a clanking sound of metal against metal, and the sound would be mostly heard when you are driving on uneven ground. The more the issue gets worse, the louder the noise.

Finally, it would break out entirely, which could be a critical problem. When you hear the noise, check your lower control arm immediately.

Vibrations in the Steering Wheel

If the lower control arm is defective, it will wear out the ball joints and the bushings. This would cause the shaking of the steering column, causing the wheel to start vibrating as you drive.

Normally, this happens whenever you are accelerating and reduces when you have increased the speed.

Unequal Tire Wear

A bad lower control arm could cause misalignment of your vehicle, resulting in uneven wear out of your tires. When you notice that 1 or 2 tires are worn out compared to the others, your lower control arm might be at fault.
