lower control arm bushing symptoms

60% of all accidents occur due to problems with your car’s tires, brakes, or suspension. And guess what can cause all three of these problems. You guessed it right it is the control arm bushing.

If you’re experiencing poor handling, vibration, or noise from your car, it may be due to a bad control arm bushing. Control arm bushings are important suspension components that help keep your car aligned and handle the road smoothly.

In this article, we’ll discuss what control arm bushings are, how they work, and the symptoms of the bad bushing. We’ll also provide tips on how to fix and prevent a bent control arm in the first place. Finally, we’ll answer some of the most frequently asked questions about control arm bushings.

What are Control Arm Bushings?

Control arm bushings are an essential component of your vehicle’s suspension system. These bushings provide a connection between the control arms and the chassis, and they help to absorb impact and reduce vibration. Over time, these bushings can wear out and need to be replaced.

Where is Control Arm Bushing Located?

On most vehicles, the control arm bushing is located at the point where the control arm meets the chassis over a ball joint. It is usually a rubber or polyurethane bushing that acts as a cushion between the metal components.

How Does a Control Arm Bushing Work?

The control arm is the link between the chassis and the wheel hub and serves as the pivot point for the wheel. There are two different types of control arms. A lower control arm connects the chassis to the wheel hub, while upper control arms connect the chassis to the strut assembly. A vehicle will have either two lower control arms or one lower and one upper control arm.

The bushing is a rubber or polyurethane sleeve that sits between the control arm and chassis, allowing it to pivot smoothly. The main purpose of control arm bushing is to provide a smooth surface for the control arm to pivot on and absorb any harshness or vibration from the road.

Symptoms of Bad Control Arm Bushings

There are several symptoms that can indicate you have bad control arm bushings. These include:

  1. Knocking Sounds
  2. Stiff Suspension Movement
  3. Vibrating Steering Wheel
  4. Uneven Tire Wear
  5. Poor Braking
  6. Misaligned Steering Wheel

Let us explain these symptoms briefly:

1. Knocking Sounds:

If you hear knocking sounds coming from your suspension, it could be a sign of bad control arm bushings. The bushings may be worn out or broken, causing the metal components to knock against each other. Although there may be some other cause of knocking sound from the suspension, such as loose parts still, it is best to get the control arm bushings checked first.

2. Stiff Suspension Movement:

If the control arm bushings are worn out, they will not be able to support the weight of the suspension components properly. This can cause the suspension to feel stiff and unresponsive. You may also notice that your vehicle rides rough over bumps and potholes. The comfort of your ride is highly compromised since control arm bushings are responsible for absorbing shocks and making your ride smooth.

3. Vibrating Steering Wheel:

Control arms serve as a link between the steering wheel and your car’s wheels. If the bushings of control arms are worn out, they will not be able to properly transfer the force from the steering wheel to the wheels. This can cause your steering components to vibrate, making it difficult to control your vehicle. This vibration will become highly noticeable, especially when you are trying to accelerate or stop your car.

4. Uneven Tire Wear:

If you notice that your tires are wearing unevenly, it could be a sign of failing control arm bushings or a bent steering arm. The main reason behind the uneven tire wear is that the alignment of your wheels gets affected due to the worn-out bushings.

The wheels cannot point in the right direction, which causes the tires to scrub against the road surface. Moreover, the surface area of a tire that is in contact with the ground might also decrease due to worn-out bushings. Because in this case, a stiff control arm will prevent the full face of the tire from touching the ground. This leads to uneven and premature tire wear.

5. Poor Braking:

If the control arm bushings are not in good condition, it can cause your brakes to work less efficiently. The brake pads may not be able to apply enough pressure on the rotors, resulting in longer stopping distances. In some cases, the bad control arm bushings may also cause the brake pedal to feel spongy.

6. Misaligned Steering Wheel:

If you notice that your steering wheel is not aligned properly, it can be a sign of bad control arm bushings. The worn-out bushings will not be able to support the steering knuckle properly, resulting in the misalignment of the steering wheel. This can make driving your vehicle difficult and dangerous.

These are some of the most common bad control arm symptoms. If you notice any of these symptoms, it is important to get your vehicle checked by a mechanic as soon as possible. Ignoring these signs can further damage your suspension components and may even cause an accident.

What Causes a Bad Control Arm Bushing?

One of the most common causes of a bad control arm bushing is simply wear and tear. Over time, these bushings can become worn down, making them less effective at doing their job. This can lead to several problems, including poor handling, premature tire wear, and even decreased fuel efficiency. In some cases, control arm bushings can simply break down, causing even more serious problems.

Another common cause of control arm bushing problems is improper installation. If these bushings are not installed correctly, they can become damaged or dislodged, leading to the same sorts of problems as wear and tear.

Finally, control arm bushings can be damaged by road conditions. If you hit a pothole or other large object, it can cause the bushing to become damaged or dislodged. This can then lead to poor handling and other problems.

How To Prevent Control Arm Bushings From Going Bad?

You can do a few things to prevent the control arm assembly from going bad.

1. Inspect your control arm bushings regularly and replace them if they show signs of wear.

2. Avoid hitting curbs or other objects that can damage the bushings.

3. Use a jack stand when working on your vehicle to avoid putting unnecessary stress on the control arm and its bushings.

4. Keep your suspension in good repair and have it serviced regularly. This will help prevent control arm problems.

5. Be sure to consult your vehicle’s owner’s manual for specific maintenance recommendations.

By following these tips, you can help extend the life of your control arm bushings and avoid costly repairs down the road.

Control Arm Bushings Replacement Cost

The cost of control arm bushing replacement will vary depending on the make and model of your vehicle and the specific location of the bushing that needs to be replaced. However, you can expect to pay anywhere from $100 to $500 for the total replacement job. In some cases, you may be able to replace just the bushing itself for a cost of $20 to $50. If you are replacing your car’s control arm bushings, it is generally not a do-it-yourself project and will require the help of a qualified mechanic.

The labor charges represent the major chunk of this replacement cost. The control arm bushing is buried deep within your vehicle’s suspension system, making it a time-consuming and difficult repair job. In addition, if you are replacing more than one bushing, the cost will increase accordingly.

There are a few things you can do to reduce the cost of this repair. First, check with your local auto parts store or dealership to see if they offer any discounts or coupons that can be applied to the replacement cost.

Secondly, if you have a warranty on your vehicle, inquire about coverage for this repair before taking your car to the mechanic. In some cases, the control arm bushing may be covered under your warranty, which could save you a significant amount of money.

Finally, if you are comfortable doing some research, you may be able to find a used or aftermarket control arm bushing that is compatible with your vehicle. While this option will likely still require the assistance of a mechanic for installation, it could end up being much less expensive than purchasing a new one from the dealership.


Control arm bushings play an important role in your vehicle’s suspension system, and when they go bad, it can lead to several problems. By being proactive and taking steps to prevent control arm bushing problems, you can save yourself time and money down the road. It is generally recommended that control arm bushings be inspected every 30,000 miles or so and replaced if they show signs of wear.

The most common symptom of a bad control arm bushing is noise coming from the suspension system. Additionally, you may notice poor handling or that your car is pulling to one side. If the problem is not addressed, it can eventually lead to tire wear and other serious issues.

If you need to replace your car’s control arm bushings, do your research to ensure you are getting the best deal possible.
