How expensive is it to replace a control arm?

Replacing a control arm typically costs between $300 and $900 per arm, including parts and labor, with variations based on vehicle type, arm (upper vs lower), and regional labor rates.

Control arms are key suspension links that connect the wheel hub to the vehicle frame and help maintain proper alignment and handling. Worn bushings or a failing ball joint can cause clunking, tire wear, and imprecise steering. Prices vary widely depending on whether you replace an upper or lower arm, front or rear suspension, and whether you use aftermarket or original-equipment parts.

Cost drivers

Understanding the factors that influence price helps car owners budget and compare quotes.

• Parts cost: Aftermarket parts are typically cheaper than OEM parts. A single control arm can range from roughly $60 to $350 for aftermarket parts, while OEM parts often land in the $100 to $500 range depending on the vehicle and brand.


• Labor time and rate: Labor for a control arm replacement generally runs from about 1 to 3 hours per arm, with shop rates varying by region (roughly $75 to $170 per hour in many markets).


• Arm type: Upper control arms are often more expensive than lowers due to construction and geometry, and some models require a ball joint replacement to be integrated into the arm.


• Suspension layout: Front independent suspension with precise alignment work can be more time-consuming than simpler setups; rear arms or multilink configurations may add complexity on some vehicles.


• Vehicle make and model: Luxury brands or European makes typically cost more, driven by parts price and labor specialists required.


• Ball joints and bushings: If the arm includes an integrated ball joint or worn bushings that must be replaced, the price rises accordingly.


• Alignment: A wheel alignment after replacement is common and can add about $75–$150 if not included in the initial quote.


• Related components: Worn tie rods, stabilizer links, or subframe bushings may be replaced in the same service, increasing the total.


• Region and shop): Labor rates vary by city and region; metropolitan areas tend to be higher than rural areas.

In sum, the total price for a single control arm replacement is shaped by the exact arm being replaced, the parts chosen, and how much ancillary work is needed.

Upper vs lower control arms

Upper control arms can be pricier than lowers because they often involve more complex geometry and sometimes integrated ball joints. Some vehicles require special tools or additional steps, which can extend labor time and push up the cost.

Front vs rear, independent vs solid axle

Front-end work for independent suspension systems tends to be more common and sometimes more labor-intensive due to alignment considerations. Rear control arms on some vehicles can involve different mounting points or multi-link configurations, potentially affecting price and duration.

What you get for your money

When you pay for a control arm replacement, you’re not just buying a single metal part—you’re purchasing a bundled service that often includes several components and follow-up needs.

• New control arm(s) with updated bushings and mounting hardware


• Ball joint replacement if the arm uses an integrated ball joint


• Mounting hardware and seals


• Optional or included alignment after installation


• Inspection of related components (tie rods, stabilizer links) and recommendations for replacement if worn


• Disposal of old parts; shop materials and disposal fees may apply

Concluding note: Be sure to confirm exactly what your quote includes—some shops include the alignment in the price, while others itemize it separately.

DIY vs professional service

While some experienced hobbyists may tackle suspension work, a control arm replacement requires proper tools, torque specifications, and an alignment. Improper installation can compromise steering safety and tire wear, so most drivers choose a professional shop. If you’re considering a DIY approach, check your vehicle’s service manual for correct procedures and consult local labor rates to compare against shop quotes.

Typical price ranges by vehicle type

Prices vary by the vehicle’s design, parts availability, and labor requirements. The ranges below are approximate per-arm totals in the United States as of 2024–2025, and can vary by region and shop.

• Economy/compact sedans: roughly $300–$700 per arm


• SUVs and crossovers: roughly $350–$900 per arm


• Luxury and European models: roughly $600–$1,200 per arm


• Heavy-duty trucks and vans: roughly $500–$1,000 per arm

Note: If you replace both arms on the same axle, multiply these figures accordingly, and expect alignment costs to apply. Some vehicles may require additional parts or a suspension kit, which can raise the total further.

Summary

Replacing a control arm is a mid-range repair whose cost hinges on arm type, parts choice, suspension design, and regional labor rates. Most single-arm jobs fall in the $300–$900 range, with higher prices for premium OEM parts, complex assemblies, or luxury vehicles. Always obtain a written quote that itemizes parts, labor, and alignment, and consider addressing related wear items at the same time to avoid future service calls.

Can I drive a car with a bad control arm?

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. 

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.
