All modern cars feature some kind of suspension system to make driving smoother. Control bushings are an important part of your suspension system that can break.
When a bushing is broken, it affects your car’s performance and stability, so you want to get it replaced sooner rather than later. On average, you can expect to pay about $350 to replace one bushing.
So replacing all four bushings on your car would cost around $1,200. The typical price range you can expect is between $200 to $500 per bushing, depending on the make/model of your car and your mechanic’s location.
Luxury brands and high-performance vehicles may cost upwards of $800 per bushing. Several things factor into the cost of replacing control arm bushings.
So we put together this comprehensive article on control arm bushing costs. We will talk about replacement costs for various popular models of cars and also talk about part costs.
Control arm bushings are an integral part of your car’s suspension system that works to minimize bumps and vibrations when driving. Bushings connect to the springs in the suspension system and are what allows the car’s wheels to move up and down when going over uneven terrain.
Without bushings, your tires would not be able to react properly to the road, and your ride would be a lot bumpier. More generally, bushings attach to the control arm, which itself attaches to the wheel axle.
Control arm bushings are also closely related to the ball joint, which allows your car’s tires to move side-to-side. These three components—control arm, bushings, and ball joint—collectively work together to provide a smooth riding experience while driving.
You can think of bushings like the cartilage in your shoulder joints. Cartilage absorbs shock and makes it easier to move your arm back and forth. Control bushings do the same for your wheels and tires.
Bushings often take a large brunt of the force from your tires and the ground as they sit parallel to the direction the force travels. As such, they can take a lot of wear and tear over time. Eventually, your bushings wear down and need to be replaced.

How Much Does it Cost to Replace Control Arm Bushings?
You can expect to pay an average of $350 per arm to replace control bushings. The typical price range is anywhere between $200 to $500 per arm. The following table has the average cost per bushing replacement. These figures are estimates, and your actual costs may differ.
|Make/Model||Price (per bushing)|
|BMW 3 Series||$550|
The range of bushing replacement costs hovers between $200 on the low end and $500 on the high end. More expensive luxury brands, such as Audi, can cost up to $800 per bushing.
Bushing Parts Cost
The actual bushing parts are fairly cheap. It is labor that is the most expensive. This is because the mechanic has to disassemble your wheel and suspension to remove the bushing and install a new one.
If you have the know-how, you can buy the parts and replace them yourself to save some money. You can buy control arm bushings for between $20 to $80per piece, so a set of four would run you anywhere between $80 to $300.
Here is a table showing the average cost for various control arm bushing replacements.
|Whitelines W53377A Control Arm Bushing||$65|
|MOOG K2007874 Control Arm Bushing||$30|
|A-Premium Lower Control Arm Bushing for BMW||$30|
|KYB SM5166 Control Arm Bushing||$10|
|Energy Suspension 4.3133G Central Arm Bushings||$30|
|Whiteline W63378 Rear Trailing Arm Bushing||$62|
|Prothane 14-210 Control Arm Bushing Kit||$97|

One of the best things about bushings is that many are universal and compatible with a wide range of cars, so you probably won’t have to spend time looking for a specific model.
That being said, some brands, suc as BMW and Mercedes, use signature parts that can’t be switched out with generics. Make sure you understand part compatibility options for your car before buying.
Most of the time, after you replace your bushings, you may need to re-align your suspension system so it is balanced. Fortunately, re-alignment is cheap and shouldn’t cost you more than $100 per session.
To keep your suspension and bushings in good condition, we recommend re-aligning your system once every two to three years.
Depending on the state of your control arms, you may also need to replace your ball joints. Like bushings, ball joints wear down over time and can be damaged by exceedingly rough terrain.
You can expect to pay anywhere between $200 to $300 to replace each ball joint. So replacing all four on a car would run you approximately $800 to $1,200 total.
One other component you may need to replace is your suspension springs. Like all springs, suspension springs lose rigidity over time and become less effective.
The typical car owner can expect to pay around $350 for a single suspension spring replacement. For all 4 springs, that would come out to around $1,400 for a full replacement.
Generally speaking, you cannot repair suspension springs so you have to replace them if something goes wrong.
The control arms are the main structural support of your car’s suspension system. They hold both the bushings and ball joints. If the mount holding the bushing or ball joint is broken, then you may have to replace the entire control arm.
You can replace a single bottom control arm for anywhere between $100 to $300. Similar to control bushings, the actual arm part is not very expensive. But replacement is labor-intensive as the mechanic needs a special tool to access and remove the arm.
Factors that Affect the Cost of Replacing Control Arm Bushings
- Control arm type. There are two major types of control arms: upper and lower arms. Upper arms are smaller and usually play a support role, while lower control arms are larger, more durable, and take the brunt of the weight. lAs such, lower control arms bushings are usually more expensive to repair because they need to be bigger and stronger. Some cars don’t even have upper control arms.
- Materials. Most control arm bushings consist of an outer metal sleeve, inner metal sleeve, and a rubber or polyurethane bushing that absorbs shock. High-grade materials such as stainless steel or neoprene rubber are more durable and higher-quality but are consequently more expensive.
- Car make/model. Most bushings are designed to work with a wide range of vehicle makes/models. However, some car manufacturers use specific parts that can’t be replaced with generics. Typically, luxury brands require special repairs from a registered mechanic.
- Vehicle age. Older cars are usually less expensive to repair than newer cars. That being said, it might be hard to find parts compatible with certain older models.
Signs of Broken Control Bushings
Here are the most common signs of broken control bushings.
If you have a broken bushing, the most obvious sign will be decreased stability when driving. If you notice your car vibrating more than usual, or there is a lot of feedback from debris on the road, then one of your control bushings could be kaput.
Uneven Tire Wear
The control arm bushings absorb shock impact from the road and give your tires room to move up and down. If a bushing is broken, that tire will experience more force than normal. The result is that the treads on your tire can wear down faster. If the sides of your tire treads are uneven, then your control bushing might be the culprit.
Vibrating Steering Wheel
By absorbing vibrations, the bushings also prevent any vibrational feedback in the steering wheel. If a bushing is broken, you might feel vibrations and rattling when you turn your car wheel or press on the brakes. Broken bushings may also make it harder to turn your car’s steering wheel.
Control bushings are not directly connected to your car’s braking system, but they can still negatively affect it. A broken bushing can make braking less efficient, as the control arm can’t absorb any of the force that friction generates on the tires.
Clunking or Rattling Noise
Another common sign of a broken control arm bushing is a clunking or rattling sound coming from your tires when you turn. Without the support of the bushing, other parts on your control arm might start to grind against one another.
Frequently Asked Questions
What do control arm bushings do?
Control arm bushings work to reduce vibration and shock when driving on uneven roads. The arm bushings work with the control arm and ball joints to let the wheels move up/down and side-to-side while driving. Without bushings, your car ride would be much bumpier.
How much do replacement control arm bushings cost?
Most car owners can expect to pay about $300 to completely replace a single bushing. That means you can expect to pay around $1,200 to replace all four bushings simultaneously.
Generally, parts cost between $100 to $200, while labor costs between $200 to $300. Depending on your car make/model, replacement costs may be higher.
How often should I replace control arm bushings?
The exact lifespan of your control arm bushings depends heavily on how often you drive and what kind of terrain you normally drive on. Assuming you mostly drive on paved roads and drive on rocky terrain infrequently, your control arms should last at least 100,000 miles.
Keep in mind that various things can decrease bushing life space, such as failing to inflate or rotate your tires, or neglecting to tune up your suspension.
Can I drive my car with broken control arm bushings?
A broken control arm bushing will not render your car undrivable, but it can cause other problems. Neglecting a bokeh bushing can damage your entire suspension system and damage your tires, both of which can be very expensive to fix.
So it’s in your best interest to get a broken bushing fixed quickly.
Can I replace only my control bushings?
Most of the time, when replacing your control bushings you should at least consider replacing other parts of your suspension system. Bushings break down from time and use, so if they are worn down then other parts of your suspension like the ball joints and springs might be worn down too.
Sometimes, you can just replace your bushings and leave everything else intact. Generally speaking, you should replace all four bushings at the same time to keep your suspension as even as possible.
How long does it take to replace control bushings?
Mechanics normally need a special tool to access the control arms and attachments, which adds extra labor time and costs. It should take a pro between an hour to two hours to change a bushing, depending on your car and the extent of the damage.
So it can take anywhere between four to eight hours to change out a set of four.
Control bushings are an important yet underappreciated part of your car’s suspension system. Many people don’t even know they exist, so when there is a suspension problem, they don’t know what’s wrong.
Bushings are relatively cheap to replace compared to other car parts, but the costs can add up quickly as you normally have to replace all of them at once.
So, when shopping around for control arm bushing replacements, make sure you get quotes from several mechanics to compare prices. You can most likely save $50 to $100 just by finding the right mechanic.
