What Are Sway Bar Links And What Does It Do?
The sway bar link also known as the stabilizer bar link is used to attach the sway bar with either the control arm or the spindle. The sway bar is a simple bar that connects the left and right suspension components in an independent suspension system. Sway bars are also referred to as anti-roll bars, anti-sway bars, roll bars, or stabilizer bars. The job of the sway bar is to reduce body roll and keep all four wheels of a vehicle grounded as the vehicle makes a turn. The sway bar link helps connect the sway bar to the suspension system and acts as a pivoting point to allow the sway bar to flex or rotate as the vehicle moves.

How Many Sway Bar Links are on a Car?
The number of sway bar links on a car depends on the car’s make and model. Most cars have two sway bars, one in the front and one in the rear, that are joined together to the car’s suspension by the sway bar links. However, some older car models may only have a sway bar on the front axle.
What are the Two Types of Sway Bar Links?
There are different types of sway bar links, but the most common ones are bolt type, hybrid, and ball joint style. The bolt type sway bar link is the most basic type and is used in most cars. It consists of a bolt that goes through the sway bar and the suspension component. The hybrid sway bar link is a combination of the bolt type and ball joint style sway bar links. The ball joint style sway bar link contains two ball joints on either end that connects to the sway bar and suspension component, which is usually the lower control arm.
What are Stabilizer Links?
A stabilizer bar system is part of most vehicle suspension systems. It is designed to reduce body roll and fine-tune the suspension by connecting the front wheels (left and right), and in many cases the rear wheels, through short links connected to a suspension component at each wheel. Stabilizer bars are also referred to as anti-sway bars, sway bars, anti-roll bars, and roll bars.
The stabilizer bar system consists of several components, including the stabilizer bar itself, stabilizer links, stabilizer link bushings or sockets, stabilizer bar to vehicle frame bushings, and bushing brackets to hold the bushings in place against the frame or unibody member. All of these components are designed to help force opposing sides of the vehicle to lower or rise to similar heights and reduce the body roll of the vehicle on curves, sharp corners, or over large bumps.
What are End Links on a Car?
End links, also known as sway bar links, serve as a connection between your vehicle’s sway bar (anti-roll bar) and the vehicle’s suspension. The sway bar helps to decrease the amount of weight transfer, keeping a greater contact patch of the tire on the ground, increasing the grip & performance of the vehicle. Whenever you change a vehicle’s ride height, the suspension geometry changes and in order to correct the angles that are changed, shortened or adjustable end links may be needed. The end link below is adjustable which can be shortened or lengthened in order to correct the sway bar angle.

2 Which Type Of Sway Bar Link Should I Choose?
Depending on the suspension design, the sway bar link used in a particular vehicle can vary and so there are a few different types available. The various categorizations are as follows:
Based On Size
Extended: Extended sway bar links are designed for vehicles that have been lifted or raised from their original ride height or modifications made to the suspension system.
Non-Extended: Non-extended sway bar links are meant for vehicles that have not undergone any modifications with the suspension system.
Based On Construction
There are three types of sway bar links based on their design. These are:
1. Ball Joint / Socket Style: This type of sway bar link contains two ball joints on either end that connects to the sway bar and suspension component, which is usually the lower control arm. Ball joints allow the sway bar and control arm to move relative to one another while still transferring the force from both sides. This type of sway bar link can be found in many modern independent suspension systems. The ball joints provide a flexible connection point which allows the sway bar and control arm to move freely relative to one another providing a smoother ride.
2. Bolt Type: A bolt-type sway bar link consists of a bolt with bushings on either end that connect the sway bar to the control arm. These bushings provide a softer connection point which provides a smoother steering response and a more comfortable ride.
3. Hybrid style: A hybrid sway bar consists of a bushing and bolt connection on one side and a ball joint on the other. This enables the sway bar to move with greater freedom on the ball joint end and has a supple connection on the bushing end combining the advantages of both styles of connections.
Based On Bushing Material
The bushing used in a bolt-type sway bar link can be made of different materials which offer different advantages. The factory-equipped bushings are usually made of rubber that is softer but provides a more comfortable ride. However, this ride comes at the cost of more body roll during turns due to the softer nature. Additionally, rubber bushings are cheap and maintenance-free—no need to lubricate them.
The other type of bushing used is polyurethane which is harder and much more durable which makes them last longer and minimizes body roll during cornering. One drawback to this is a firmer ride due to the hard nature of polyurethane bushings.
Metal bushings are made of metals such as iron and steel. They are commonly found in old car models and heavy trucks. They are preferred in heavy equipment due to their stiffness and ability to withstand stretching and abuse. They last a very long time but are prone to rust which can cause premature sway bar link failure. Metal bushings provide good handling performance but can be harsher on the ride quality.
What Are The Things I Should Consider When Buying New Sway Bar Links?
A. Bushing Material
Different types of bushings offer different advantages. It is important to buy the right type of bushing according to your specific needs. Rubber bushings are quite affordable and offer comfortable ride quality but can cause excess body roll when turning, whereas polyurethane bushings give a harsher ride but are firmer which provides better handling characteristics. Metal bushings are a long-lasting option but are vulnerable to corrosion and rapid wear if not lubricated regularly. They are ideal for heavy-duty applications as they can withstand more abuse before failing.
B. Sway Bar Link Style
Sway bar links are available with varied connection types as discussed earlier. The links can be attached to the suspension components either by a ball joint or directly bolted with bushings or can have both a bushing and ball joint on either end. The type of sway bar you need to choose depends on the original type your vehicle came with. Check the existing sway bar link type and buy the same type of link.
C. Greasable Vs Non-Greasable Design
Some sway bar links need to be lubricated regularly for the best performance and to prolong component life. Bushings, as well as ball joints, need to be greased regularly to prevent wear and tear. Failing to lubricate them can cause excess wear in metal bushings and ball joints that will cause the link to fail eventually. To counter this, maintenance-free components or non-greasable design is used which does not require regular greasing of the ball joint or bushings. However, these designs generally have a shorter lifespan compared to greasable designs. Maintenance-free or non-greasable sway bar links are ideal for compact and sedan cars where the wear and tear on various suspension components is lower. Whereas for heavy-duty applications, the greasable design is recommended.

5 What Are The Warning Signs That My Sway Bar Link Is Failing?
Sway bars are made of long-lasting and durable metal bars but the bushings and ball joints on sway bar links are susceptible to wear and tear and can fail over time with prolonged use. A broken sway bar link can affect the handling and steering performance of the vehicle, increasing body roll, and reducing steering response. This makes it necessary to find failure which is evident from the following signs of failure.
How Long Do Sway Bar Links Last?
The lifespan of sway bar links depends on the quality of the parts and how well they are maintained. Car owners need to replace their sway bar links once throughout the car’s entire lifespan. Expect them to last at least 50,000 miles. However, if you drive down roads that are excessively bumpy and rough, the links may only last around 50,000 miles. The links provided by the manufacturer on your new car will last a long time. Useful life of 150,000 miles is not unusual.
Poor Handling / Loose Steering Wheel
A broken sway bar link can be dangerous and must be dealt with immediately as it will result in handling issues. Poor handling can also rise if the front or rear sway bar link’s bushings are corroded. You may also notice your steering wheel to be a bit lose and the vehicle will start swaying as you make a turn.
Unusual Noises
As the sway bar link ball joints wear, the metal components within start to contact each other which is evident from grinding or knocking noise coming from the suspension as you make a turn or drive over a bump. Similarly, torn bushings in the sway bar links will cause metal-on-metal contact causing a grinding or clunking noise. If the sway bar link is faulty, then it can detach from the frame completely. This can result in the sway bar links hitting other suspension components and will produce a metal clunking noise from the wheel wells.
Increased Body Roll
Since sway bar links are connection points between the suspension and the sway bar itself, faulty or broken sway bar links can cause increased body roll. This is because the weight transfer that is possible due to the sway bar connection is broken and so the vehicle tends to lean or roll as you negotiate a turn. You will experience body roll especially while cornering affecting the handling and the steering performance of the vehicle.
6 Can you Drive with a Broken Sway Bar Link?
You can still drive your car with a broken sway bar link, but the performance of the vehicle will be affected. The sway bar link is responsible for stabilizing the vehicle by reducing how much your car leans when turning. If the sway bar link is broken, the car’s stability will be compromised, and the steering wheel will loosen, resulting in an unstable drive.
If your sway bar link is broken, it is recommended that you drive at much lower speeds, less than 50 km/h. Your drive may not be as smooth because your steering wheel would be looser, but you won’t have to risk losing control of your car, as you would if you were driving at a higher speed.
How Important are Sway Bar Links?
Sway bar links are an important part of your vehicle’s suspension system. They connect the sway bar to the suspension and help to reduce body roll when turning or driving on uneven surfaces. Without functioning sway bar links, your car’s handling and stability can be compromised. Here are some of the benefits of functioning sway bar links:
- Improved Handling: Sway bar links help to reduce body roll and keep your car level when turning or driving on uneven surfaces. This can help to improve handling and make your car easier to control.
- Better Stability: When your car is stable, it is less likely to roll over or lose control. Sway bar links help to keep the car level and prevent it from tipping over.
- Safer Driving: The proper functioning of sway bar links is crucial for safe driving. They help to improve the car’s handling and stability, which can prevent accidents and keep you and your passengers safe.
1 What Does A Sway Bar Do And Why Do I Need Them?
The primary purpose of a sway bar is to prevent the leaning of the vehicle which normally occurs during a turn. While making a turn, the force is distributed towards the outside (weight will shift to the left if you are making a right turn). This will raise the outer wheels. But, with a sway bar, the inner and outer tires are maintained at the same level which levels the entire vehicle. Sway bars ensure that your vehicle doesn’t roll too much while you handle turns. They also help to maintain the overall stability and prevent uneven wheel contact.
Safety – An important reason most vehicles have sway bars. If your vehicle upends too much, it can be dangerous as it may even topple. Apart from the obvious danger of a rollover, sway bars prevent the sliding of the vehicle in turns. This in turn avoids the wheel from losing grip and causing skidding. It will be harder to control your vehicle especially while turning or while applying brakes.
What Are The Functions Of Sway Bar?
There are two important functions of sway bar:
- It reduces the car body’s tendency to lean. The roll stiffness of the vehicle will affect the leaning of the body but it does not affect the shifting of weight from the inside to the outside wheels.
- It controls the handling balance of the vehicle. Understeering or oversteering behavior will force a vehicle to lean. The proportion of roll stiffness at the front will also change the front and rear axles’ reactions. This forces the outer front wheel to run at a higher or lower slip angle. This situation is kept under control by the sway bars.
How many sway bars does a car have?
Most cars typically have two sway bars—one for the front suspension and one for the rear suspension. These sway bars are designed to help control body roll and improve stability during turns, contributing to better handling characteristics. The front sway bar is usually located near the front axle, connecting the left and right front suspension components, while the rear sway bar is positioned similarly for the rear suspension.
How important is a sway bar?
A sway bar is a crucial component in a vehicle’s suspension system, playing a vital role in enhancing stability and handling. It reduces body roll during turns, helping to keep the vehicle level and improving overall control. The sway bar’s significance lies in its ability to distribute forces between the left and right sides of the suspension, minimizing the impact of weight transfer during maneuvers. This results in improved traction, reduced sway, and a more predictable driving experience, particularly in corners or challenging road conditions. In essence, a sway bar contributes significantly to a vehicle’s safety, handling performance, and the overall driving experience.
What Are The Factors I Should Consider Before Buying Sway Bars?
1. Aftermarket Sway Bars
The right sway bar for your vehicle depends on how you drive and where you drive. Are you a full-time racer? Then aftermarket sway bars can be an ideal choice. Though the aftermarket sway bars are stiffer, they can improve the performance and the handling characteristics of the vehicle.
2. Stiffness
When going around turns, the outer wheels have a tendency to lift up due to various forces. A stiffer sway bar can help in such situations by lowering the outer end and leveling the vehicle which will increase traction at the wheels making you corner faster and with more confidence. This is why an increase in stiffness is often preferred when wanting track focused handling dynamics from your vehicle.
The stiffness is measured with regard to factory sway bars stiffness. So a stiffer sway bar for a particular vehicle will carry a 50% or 100% stiffer stock sway bar distinction on it. Use this percentage to decide how much stiffer you want your sway bars and consequently how much sturdier you expect your suspension to handle during cornering.
If you are using your vehicle on a daily basis just for normal driving then stock sway bars are perfect. Unless your factory sway bars allow body roll, then opt for an increase of about 50% stiffer bars. Sway bars with stock stiffness will offer you a factory-like ride quality.
If you drive regularly on the track or have a track car, then the sway bars with increased stiffness is usually your ideal choice. However, every vehicle is different and so is their suspension. This means you may have to use a trial and error method to determine the best stiffness sway bars for your car. It all depends on your personal preference and what you want from your vehicle. Remember that stiffer sway bars will also impact the everyday ride quality and you may find your ride to be a bit harsher due to the increased stiffness.

How Can Sway Bar Affect My Vehicle’s Dynamics?
Front-Wheel Drive (FWD), Rear Wheel Drive (RWD), and All-Wheel Drive (AWD) cars behave differently. So when you upgrade the sway bars, they will respond differently.
1. Front Wheel Drive (FWD)
To turn and transmit power to the ground, the front-wheel-drive relies on front tires. Front-wheel-drive cars usually tend to under-steer. By fixing a stiffer rear sway bar, you can reduce the under-steer. If you are planning to upgrade the front sway bar, you ought to be careful, as too much stiffness can cause the inside front wheels to lift. As front tires transmit power to the ground, they can drastically affect the handling of the vehicle and the grip negatively.
2. Rear Wheel Drive (RWD)
They usually tend to oversteer, as they allow the rear of the car to pivot around the front. By fixing a stiffer front sway bar on a rear-wheel drive, you can reduce the oversteer. To minimize the body roll, you can always stiffen the front sway bars, but you will have to keep in mind that they don’t affect the suspension dynamics negatively.
3. All Wheel Drive (AWD)
A combination of both the front and rear-wheel-drive is the All-Wheel-Drive cars (AWD). All-Wheel-Drive cars can either oversteer or understeer. In simple terms, if your All-Wheel-Drive car over-steers, then install a stiffer front sway bar and if it under-steers, then fix a stiffer rear sway bar. Adjustable sway bars are also available in the aftermarket where you can either stiffen or soften them, depending on what you are looking for.
4. Things To Be Noted
It doesn’t mean that stiff sway bars are always better. Increasing the stiffness of a rear-sway bar can reduce understeer in a front-wheel drive. But, an overly stiff rear sway bar will induce oversteer, which makes it difficult for driving. In a similar way, an overly stiff front sway bar will probably under-steer in a rear-wheel drive. It’s all about “balance” when it comes to suspensions.
Now that you are aware of the importance of a sway bar, the next question is, “Do I need a new one”. Most of the time it’s not always the sway bar that causes the actual problem, but other related components such as sway bar link, sway bar bushings, sway bar frame bushings, sway bar end bushings, and much more. Before we get to know the symptoms, let’s see what are sway bar bushings and sway bar links.
Top Picks For Sway Bar At PartsAvatar
2 What Do Sway Bar Bushings Do And Why Do I Need Them?
At times, trouble can arise in your vehicle not just because of the sway bars, but other related components such as sway bar bushings and sway bar links that connect them. Sway bar bushings connect the sway bar and the vehicle’s frame. As you make sharp turns, these bushings keep the vehicle under control and stable. With the sway bar bushings in place, the sway bar can rotate and flex freely within the rod’s position. Also, it ensures that the swaying rod stays or fits in place, relative to the rest of the vehicle. Before we get to know the symptoms of failing sway bar bushings, let’s look into the different types available.
Which Type Of Sway Bar Bushings Should I Choose?
1. Metal Bar Bushings
Made of metals such as iron and steel, these bushings can be easily found in heavy trucks and old car models. They have the ability to withstand the stretch and abuse because of their stiffness and hence they are preferred in heavy equipment. However, they are vulnerable to corrosion and you will have to always lubricate regularly to prevent squeaking sounds and to prolong their life. They are also much stiffer and have no give which can result in a slightly harsher ride.
2. Rubber Bushings
Rubber bushings are the common ones that you can find in modern cars. Because of their ability to withstand friction, heat, and cold, rubber is usually preferred. They are cost-effective and easy to maintain. You also don’t have to lubricate them constantly. These bushings have shorter lifespans compared to other types as rubber naturally is less sturdy than other materials. They can stretch easily when put under extreme stresses resulting in torn or broken bushings which affect suspension alignment
3. Urethane/Polyurethane Bushings
One of the better solutions that manufacturers have come up with, to replace the rubber bushing is urethane/polyurethane bushings. They are stiffer when compared to rubber and hence they are the better option for holding the alignment of suspension parts such as leaf springs, control arms, and more. This reduces body roll and provides more traction while making turns. They are as rigid as metal bushings, but they don’t wear out quickly. But, they are expensive compared to the above two.
4. Greasable/Non-Greasable Bushings
Greasable sway bar bushings have a special channel allowing the lubricant to flow through the surface of the bushings. This helps to minimize friction and noise. They last for a long time providing a smooth and safe ride. For non-greaseable bushings, you don’t need any grease to operate. They are affordable and easy to maintain. But they are not long-lasting and may start to squeak over time.
What is a sway warning?
Sway warning is a feature in some modern vehicles that provides a warning to the driver when the vehicle exhibits signs of swaying or unintentional lane departure. Using sensors and cameras, the system monitors the vehicle’s position within its lane and alerts the driver if it detects swaying or drifting without the use of turn signals. This technology aims to enhance driver awareness, promoting safer and more controlled driving by preventing unintentional lane departures.
How to tell if sway bar bushings are bad?
Worn or damaged sway bar bushings can negatively impact your car’s handling and stability. Here are some signs that your sway bar bushings may be bad
1. Excessive Noise: If you hear clunking, squeaking, or rattling noises, especially when going over bumps or during turns, it could indicate worn or damaged sway bar bushings.
2. Poor Handling and Stability: Bad sway bar bushings can result in decreased stability and compromised handling, especially during turns. You might notice increased body roll or a feeling of instability.
3. Uneven Tire Wear: Irregular wear on your tires can be a sign of poor suspension components, including sway bar bushings. If you observe uneven tire wear, it’s worth checking the condition of the bushings.
4. Visible Damage or Displacement: Inspect the sway bar bushings for visible signs of damage, such as cracks, tears, or pieces missing. Additionally, if the bushings are displaced from their proper position, they may need replacement.
5. Oil Leaks: Some sway bar bushings are lubricated, and leaks of the lubricating oil may occur if the bushings are damaged. Inspect for any signs of oil around the bushing area.
6. Excessive Play in the Sway Bar: If you can easily move the sway bar by hand or notice excessive play when pushing or pulling on it, the bushings may be worn out.
7. Changes in Steering Responsiveness: Worn sway bar bushings can affect the responsiveness of the steering. If you notice changes in how your car responds to steering inputs, it could be a sign of bushing wear.
If you suspect an issue with your sway bar bushings based on these signs, it’s advisable to have your vehicle inspected by a qualified mechanic. They can assess the condition of the bushings and recommend replacements if necessary to ensure optimal performance and safety.
What Are The Warning Signs Of A Bad Sway Bar Bushings?
With the proper care, the sway bar bushings can last for a long time. However, bushings will wear out eventually. A damaged sway bar bushing will not be able to support the sway bar. Following are some of the signs of bad sway bar bushings.
1. Squeaking Noise From The Car
Just like any other joint, you will have to lube the sway bar bushings regularly. This reduces the friction between the metal surface of the bushings and the sway bar that are in contact with each other. This acts as a protective layer, keeping the rust away. If there is no sufficient lubrication, then the bushings will grind against the sway bar. You’ll probably hear squealing or squeaking noise while making sharp turns or while driving through rough terrain. This is a sign that your sway bar bushings are worn out. Squeaky noise can also arise if the sway bar and its bushings are corroded.
2. Sluggish Response By Your Vehicle
As you drive your car daily, you may have a good knowledge of how your car handles on the road. But, is your car responding too slow while making quick turns? Does your vehicle seem less stable while turning in the corner? This is an early warning sign that the sway bar bushings are warning-out. If the sway bar bushings are worn-out, they will not be able to hold the sway bar in position as they may move freely, especially while making turns. This can be dangerous as the car will lose control and become unstable, thereby increasing the risk of an accident.
3. Rattling/Knocking Noise Beneath The Car
The sway bar is located under your car. If the sway bar bushings are worn-out, torn, or completely broken, they will not be able to hold the sway bar steadily. This unstable rod will produce a rattling or knocking noise every time the car bounces. The noise will eventually get louder when you try to steer your vehicle on either side. You can hear this noise, from the front of your vehicle, every time you step your foot on the floorboard.
