How much should it cost to replace control arms?

For most cars, expect to pay roughly $300 to $1,000 per control arm when you replace it, depending on parts, labor, and vehicle specifics. This article breaks down the typical costs, what drives price differences, and how you can plan for the repair.

Understanding what drives the price

Control arms are a key part of your suspension. Replacing them involves parts cost, labor time, and sometimes a wheel alignment after the work is done. Additional costs may apply if the ball joint is built into the arm, if both arms need replacement, or if other suspension components wear out at the same time.

Parts versus labor: what typically makes up the bill

Below are the common cost ranges you’ll see for a single control arm, with the understanding that prices vary by vehicle make/model and by shop.

• Parts: 50 to 500 per arm. Aftermarket (non-OEM) arms are often in the lower end of the range, while dealer-furnished OEM arms tend to be higher. Some vehicles with integrated ball joints or premium designs can push parts costs higher.


• Labor: 1 to 3 hours per arm, depending on accessibility. Labor rates usually run from about $75 to $150 per hour in many regions, with higher rates at premium or urban shops.


• Alignment: 80 to 150 after replacing a control arm, since geometry changes can affect steering and tire wear.


• Extra components (if needed): Replacing worn tie rods, sway bar links, or bushings can add to both parts and labor costs.

Keep in mind that some vehicles require more time due to cramped engine bays or complex front suspensions, which can push labor toward the higher end of the range.

Typical price scenarios by configuration

Prices vary depending on whether you replace one arm or both, and whether the arm is upper or lower, or includes an integrated ball joint. The following scenarios illustrate common outcomes you might encounter at a shop.

Single arm replacement (front suspension, common cases)

In many mid-range vehicles, replacing one lower control arm with an aftermarket part typically runs about $300 to $600, including labor and alignment. OEM parts from the dealer can push the total toward $500 to $900 for a single arm.

Both arms replaced (both sides)

Replacing both sides at once is common when both are worn. Expect roughly $600 to $1,200 for aftermarket parts plus labor, with OEM parts potentially raising the total to around $1,000 to $2,000 or more, depending on the vehicle and shop rates.

Upper vs lower control arm

Upper control arms can be similarly priced to lowers, but some vehicles place upper arms in tighter spaces or use different mounting hardware, which can affect labor time. Overall costs can be similar, though some luxury or performance models push prices higher.

Factors that affect cost by vehicle type

Some cars are more expensive to service due to design and part availability. Consider these factors when estimating costs:

• Vehicle make and model: Premium brands or rare models often have higher parts costs and longer labor times.


• Accessibility: Cars with crowded engines or fault-prone front ends can require more labor.


• OEM versus aftermarket: OEM parts tend to be pricier but may offer a closer fit and longer warranty.


• All-wheel drive or independent suspensions: Some setups require more work and alignment steps than others.

Always check with the shop for a vehicle-specific estimate, as these categories can shift the price by hundreds of dollars.

How to save money on control arm replacement

Smart shoppers can manage costs without compromising safety. Consider these strategies:

• Ask for a written estimate that itemizes parts, labor, and alignment.


• Shop around for quotes from at least two or three reputable shops in your area.


• Consider aftermarket parts when appropriate, and confirm with your mechanic whether they are suitable for your car.


• Look into bundled repairs: if other suspension components show wear, replacing them together can reduce incremental labor time.


• Factor in alignment and tire wear: an alignment can help avoid uneven tire wear and save money long term.

Some shops offer price breaks for replacing both arms at the same time or scheduling a bundled service with an alignment included.

When to replace control arms versus other suspension components

Control arms wear out due to potholes, off-roading, and age. If you notice a clunking noise, excessive wheel play, uneven tire wear, or misalignment, a diagnosis is warranted. In some cases, worn bushings or ball joints are the real culprits, and replacing those parts without a full control arm replacement can be an option. A trusted technician can confirm the right course of action based on inspection and test drive.

Summary

Replacing a control arm typically costs between $300 and $1,000 per arm, driven by parts quality (aftermarket vs OEM), labor time, and alignment needs. If both arms require replacement, the total can rise accordingly. Accessibility, vehicle type, and whether the ball joint is integrated into the arm also influence the price. To manage costs, obtain multiple written estimates, consider aftermarket parts where appropriate, and plan for an alignment after the repair. A proactive approach and a reputable shop can help you secure a safe, cost-effective repair that restores proper steering and tire wear.

Are control arms worth replacing?

Yes, replacing control arms is worth it for safety and performance, especially if you notice symptoms like uneven tire wear, steering wheel vibrations, or clunking noises over bumps. Driving with damaged control arms is unsafe because they are crucial for steering stability and can lead to further damage to other suspension components. It is also recommended to replace them in pairs. 
Reasons to replace control arms

• Safety: A broken or worn control arm can cause you to lose control of the vehicle, especially at high speeds or during sharp turns. 
• Performance: Control arms connect the wheels to the vehicle's frame, so worn ones can lead to poor steering stability and a rougher ride. 
• Cost-effectiveness: While an initial replacement can be expensive, it prevents further damage to other, potentially more costly, suspension parts and tires. 
• Common wear and tear: Control arms can wear out over time, with many lasting around 90,000 to 100,000 miles, though rough roads and potholes can accelerate this wear. 

Signs that you need to replace control arms

• Vibrations: You may feel vibrations through the steering wheel. 
• Noises: A clunking or banging sound from the front of the car when going over bumps or potholes. 
• Uneven tire wear: Tires may show uneven wear patterns due to improper wheel alignment. 
• Steering issues: The steering wheel may not be straight or feel loose. 

What to consider

• Replace in pairs: It is best to replace control arms in pairs to maintain proper balance and alignment. 
• Replace the whole assembly: If the bushings are worn out, replacing the entire control arm assembly is often the most practical solution, as it includes new bushings and can also include a new ball joint. 
• Professional inspection: Have a professional inspect your suspension to determine the best course of action and provide an accurate estimate. 

How many hours to replace a lower control arm?

Replacing a single lower control arm typically takes 1 to 1.5 hours in a professional shop, though the total time can range from 2 to 4 hours or more depending on the vehicle, the mechanic's experience, and potential complications like rust or integrated ball joints. If you are doing it yourself for the first time, it could take 4 hours or more, especially if you have to replace other parts or don't have a lift. 
Factors that influence the time

• Vehicle make and model: Different vehicles have different designs, which can make the job easier or more difficult. 
• Rust and corrosion: rusted-on bolts and components can significantly increase the time needed to remove them. 
• Integrated vs. separate components: If the ball joint is integrated with the control arm, it's a single job. If they are separate, it will add to the total time. 
• Mechanic's experience: An experienced mechanic can often complete the job in the lower end of the time estimate, while a less experienced DIYer will likely need more time. 
• Other necessary repairs: It's common to replace other parts at the same time, such as the tie rod ends or sway bar links, which will add to the total labor time. 
• Need for an alignment: After replacing a control arm, you should always get a wheel alignment, which adds to the overall time and cost. 

Is a control arm an easy fix?

Replacing control arms is a moderately complex task that requires specific tools and mechanical aptitude, and is not considered an easy job for a beginner. The difficulty can vary depending on your vehicle, but common challenges include rusted parts, especially seized ball joints, and the need for a final wheel alignment. 
Factors that make the job more difficult

• Rust and corrosion: Rusted bolts and seized parts can make disassembly very difficult and time-consuming. 
• Specialized tools: You will need a good socket and wrench set, a torque wrench, and a ball joint separator or pickle fork, notes AutoZone and CarParts.com. 
• Vehicle-specific challenges: Some vehicles have design features, such as a torsion bar or engine components that are in the way, that can make the job much harder or require additional steps like cutting sheet metal. 
• After-job alignment: After replacing a control arm, you must get a front-end alignment, as the new parts will change the suspension geometry. 

When it might be easier

• If you are experienced with car maintenance, such as servicing your own brakes, you will likely be able to handle the job. 
• On many modern vehicles, it is often easier to replace the entire control arm assembly, which comes with a new ball joint and bushings, rather than just replacing the bushings separately. 
• If your vehicle's suspension is not heavily rusted, the job will be much smoother. 

What to consider before starting

• Assess your skills and tools: Be honest about your comfort level and if you have all the necessary tools, especially a torque wrench and a ball joint separator. 
• Check for rust: If the control arm bolts look heavily rusted, consider having a professional do the job. 
• Factor in the alignment: Remember to budget for and schedule the final alignment after the installation is complete. 

Can I drive with bad control arms?

No, you should not drive with a bad control arm because it is extremely dangerous and can lead to a complete loss of steering control, especially at high speeds or during turns. While minor wear may allow for very limited short-distance driving, any symptoms like clunking noises, steering wheel vibration, or poor handling mean you should avoid driving and have the vehicle repaired immediately to prevent further damage and accidents.
 
Dangers of driving with a bad control arm

• Loss of control: A bad or broken control arm can compromise your ability to steer, making it unsafe to drive, especially when turning or driving at high speeds. 
• Component failure: Continued use can lead to complete failure, which could cause wheel detachment from the suspension system, leading to a serious accident. 
• Further damage: Driving with a bad control arm can cause other suspension components, such as ball joints and the steering rack, to wear out prematurely and fail, leading to much more expensive repairs. 
• Vibration and instability: You may experience vibrations, "death wobble" (violent steering wheel shaking), and poor handling, which are all signs of a compromised suspension system. 

What to do

• Do not drive: If you suspect your control arm is bad, do not drive the vehicle. 
• Get it towed: Have the vehicle towed to a trusted mechanic for inspection and repair. 
• Have it inspected: A professional can properly diagnose the problem and replace the necessary parts to ensure your vehicle is safe to drive again.
