Sway bar bushings are an important part of your car’s suspension system. They help to keep the sway bar in place and prevent it from rattling around. If worn or damaged, they can cause several problems with your car’s handling and performance.
In this article, we will discuss the symptoms of bad sway bar bushings, as well as the causes and replacement procedures. Let’s get started!
One of the first signs that your sway bar bushings are going bad is an increased noise level from the suspension. Other symptoms include body roll when cornering and a generally less responsive and comfortable ride.

What is Sway Bar? What Function Does it Serve?
A sway bar, also called an anti-roll bar or stabilizer bar is a metal rod attached to your vehicle’s suspension. A sway bar’s main purpose is to keep a vehicle’s body from rolling over during sharp turns.
It keeps the body stable, helps improve road handling, and makes the ride more comfortable for passengers. In addition, by reducing body roll, a sway bar can also increase tire contact with the ground, improving traction.
Sway bars are attached to a vehicle’s suspension at the left and right sides. The bar is usually made of steel or aluminum and is connected to the suspension by sway bar links.
The sway bar end links are attached to the body of the vehicle at one end and connect to the sway bar at the other end.
When a vehicle takes a sharp turn, the body tends to roll over. This is because the weight of the car is not evenly distributed.
The side of the vehicle closer to the turn will have more weight on it, while the opposite side will have less weight. This can cause the car to lose traction and slip or even overturn.
A sway bar helps prevent this by keeping the body stable. As the body starts to roll, the sway bar transfers some of the weight to the opposite side of the vehicle. This helps to keep the vehicle’s balance and prevents it from slipping or overturning.
Sway bar bushings are an important part of the sway bar system. The bushings are mounted on the suspension and act as a cushion between the sway bar and the vehicle’s body. They help to reduce noise and vibration, and they also protect the paint on your car.
Bushings are made of rubber or polyurethane. They are designed to compress and deflect under load, which helps to absorb shock and reduce vibration. Over time, however, bushings can wear out and need to be replaced.
Symptoms of Bad Sway Bar Bushings
Several symptoms can indicate that your sway bar bushings are going bad. These include:
- Rattling and Squeaky Noises
- Poor Suspension Response
- Bumpy Rides
- Increased Body Roll
- Uneven Tire Wear
Let’s dig a little deeper into each of these symptoms.
1. Rattling and Squeaky Noises:
One of the first signs that your sway bar bushings are going bad is an increased noise level from the suspension. You might notice a rattling noise when you go over bumps or a squeaky noise when you turn the steering wheel. As the bushings wear out, they become less able to cushion the sway bar, which causes increased sputter and vibration while accelerating.
The rattling noise is usually caused by the metal-on-metal contact between the sway bar and the links. This can happen if the bushings are worn out or dislodged from their mounting points. Loose components, such as the end links or brackets, can also cause this noise.
Squeaking noise, on the other hand, is usually caused by the wear of the polyurethane or rubber material. Poor lubrication leads to drying and cracking of the bushings, which causes the squeaking noise.
2. Poor Suspension Response:
Your car’s suspension should absorb bumps and keep the body of the vehicle stable. But, if your bushings are worn out, the suspension will not be able to do its job properly.
You might notice that your car feels less unstable on the road. It might feel like it is taking longer to stop. These symptoms are caused by the increased movement of the suspension components.
3. Bumpy Rides:
Another symptom of bad sway bar bushings is bumpier rides than usual. This means that the suspension cannot absorb shocks as well, which leads to a rougher ride. You might notice that your car feels less comfortable when driving on bumpy roads or bounces more than usual.
In addition, you might also notice that the steering shakes and feels less responsive. This is because the sway bar helps to stabilize the body of the vehicle and keep it level. When the bushings are worn out, the body is not held as securely in place, which can cause the steering to feel loose.
4. Increased Body Roll:
One of the most dangerous bad sway bar bushings symptoms is increased body roll. This means that the body of the vehicle is not being held level, which can cause the car to lose traction and slip.
Body roll is the tilting of a vehicle’s body away from its vertical center of gravity. It is most commonly experienced when cornering and is caused by the centrifugal force exerted on the vehicle’s body by its turning motion.
You might notice that your car seems to lean more when taking turns. The inside wheels might also lift off the ground, which can cause the vehicle to slide or overturn. These symptoms are caused by a loss of stability in the suspension system and can be very dangerous.
5. Uneven Tire Wear:
If your bushings are worn out, you might notice that your tires are wearing unevenly. This is because the body of the vehicle is not being held level, and the weight is not evenly distributed on the tires.
You might also notice that your car seems to drift to one side when driving straight. This is caused by the fact that the body is not level, and it causes the vehicle to pull to one side.
As a result, you might notice that your tires are wearing out faster on one side than the other. You might also see that your gas mileage is decreasing because the engine has to work harder to pull the vehicle.
What Causes Bad Stabilizer Bar Bushings?
There are a few things that can cause problems with stabilizer bar bushings.
Wear and Tear: One of the most common causes of bad stabilizer bar bushings is excessive wear and tear. Over time, the bushing can become dry and cracked, eventually breaking down completely.
Lack of Lubrication: Another common cause of bad stabilizer bar bushings is a lack of lubrication. If the bushing isn’t properly lubricated, it can dry out and become cracked, eventually leading to it breaking down completely.
Improper Installation: Another potential cause of bad stabilizer bar bushings is improper installation. If the bushing is not installed correctly, it can become damaged and may not be able to function properly.
Loose Sway Bar Links: A bad or loose sway bar link can also cause the stabilizer bar bushing to become damaged. If the link is not tightened properly, it can vibrate and cause the bushing to wear down prematurely.
Over time, any of these causes can lead to the deterioration of the stabilizer bar bushing, which can eventually result in complete failure.
How to Prevent a Bad Stabilizer Bar Bushing?
You can do a few things to prevent a bad stabilizer bar bushing.
1. Keep up With Vehicle Maintenance:
One of the best ways to prevent a bad stabilizer bar bushing is to keep up with vehicle maintenance. This includes regularly checking the bushing for wear and tear.
2. Checking the Stabilizer Bar Bushing:
You should check the stabilizer bar bushing periodically to ensure it is in good condition. To do this, you will need to jack up your car and remove the wheel. Once the wheel is removed, you should be able to see the bushing.
You should inspect the stabilizer bar bushing for any cracks or damage. If you notice any damage, it is best to replace the bushing.
3. Lubricate Rubber Bushings Well:
If your car has rubber bushings, it is important to lubricate them well. This will help to prevent the bushing from drying out and cracking.
You should apply a liberal amount of grease to the bushing. Once you have applied the grease, you should wipe off any excess so that it does not attract dirt and debris.
4. Tighten Front Sway Bar Links:
If your car has front sway bar links, you should ensure they are tight. If the connections are loose, they can vibrate and cause the bushing to wear down prematurely.
To tighten the links, you will need to jack up your car and remove the wheel. Once the wheel is removed, you should be able to see the link.
You will need to loosen the nut that secures the link in place. Once the nut is loose, you should be able to tighten the link. Once it is tight, you should replace the nut and torque it to spec.
5. Avoid Rash Driving:
You should avoid rash driving as it can cause the bushings to fail prematurely. Rash driving includes things like speeding, hard braking, and quick acceleration.
By following these tips, you can help to prevent a bad stabilizer bar bushing.
How to Replace Damaged Stabilizer Bar Bushing?
If your vehicle has damaged stabilizer bar bushing, it is important to replace them as soon as possible. Replacing your stabilizer bar bushing is not difficult, but it is important to follow the instructions carefully.
1. Jack up your vehicle and support it on jack stands. Make sure the car is securely supported before you begin working on it. Engage the parking brake as well.
A common mistake most people make while lifting a car for suspension replacement is they lift it by the frame. You must always lift the vehicle through the suspension mounting points. This will keep the load on the suspension instead of lifting the frame above it.
2. Open wheels and locate sway bar bushings. The sway bar is the long metal bar that runs across the width of your vehicle, connecting the left and right suspension. The bushings are usually located at either end of the sway bar. To access these bushings, you will need to remove the wheels.
3. Remove old bushing. To remove old bushing, you will need a bushing removal tool or a large pry bar. Insert the tool between the bushing and the sway bar. Apply pressure to separate the two parts. You may need to use a hammer to tap on the tool to loosen the old bushing.
4. Clean off any debris from inside the bushing mount. It is important to make sure the mount is clean before installing new bushing.
5. Install new bushing. To install new bushing, you will need a press or a hammer and chisel. If you are using a press, follow the manufacturer’s instructions. If you are using a hammer and chisel, tap gently around the outside of the new bushing until it is seated in the mount.
6. Reinstall sway bar and lower vehicle. Once the new bushing is installed, you can reinstall the sway bar and lower the car. Make sure to tighten all mounting hardware to the proper torque specification.
7. Test drive your vehicle to make sure everything is working properly. Replacing your stabilizer bar bushing is a relatively easy task, but it is important to follow the instructions carefully. Failure to do so could result in further damage to your vehicle.

Frequently Asked Questions
How often should you check stabilizer bar bushings?
There is no definitive answer to this question, as it will depend on several factors, including the make and model of your vehicle, driving conditions, and driving habits.
However, it is generally recommended that you check your stabilizer bar bushings at least once a year or every 15,000 miles, or more often if you notice any unusual noise or vibration coming from your suspension system.
Do sway bar bushings make a difference?
Sway bar bushings make a difference by reducing body roll. When you take a turn, the outside wheels travel a greater distance than the inside wheels. This causes the body of the vehicle to “roll” or lean to the outside of the turn.
The sway bar connects the suspension’s left and right sides so that they move simultaneously up and down. This reduces body roll, making the car more stable and better able to traction in turns.
Bushings also help to absorb some of the vibrations from the road, making for a smoother ride.
What do bad stabilizer bar bushings sound like?
If your stabilizer bar bushings are bad, you might hear a rattling noise coming from the front of your car. This is usually most noticeable when driving over bumps or potholes.
If your sway bar bushing squeak, it may indicate that they are drying out and need to be lubricated.
What happens if you don’t replace sway bar bushings?
If you don’t replace your sway bar bushings, the stabilizer bar will be able to move around more freely. This can cause several problems, including increased body roll, reduced traction in turns, and a rougher ride.
In extreme cases, a broken or detached sway bar can cause the vehicle to lose control. This is why it is important to have any suspicious noise or vibration checked out by a professional as soon as possible.
Is it safe to drive with bad sway bar bushings?
It is not safe to drive with bad sway bar bushings. If your stabilizer bar is not securely in place, it can come loose and detach from the suspension. This can cause the vehicle to lose control and lead to an accident.
If you suspect your car has a bad sway bar bushing, it is important to have it checked out by a professional as soon as possible.
