Lower control arm replacement typically costs between $300 and $800 per arm at an independent shop, or $400 to $1,000 at a dealership, depending on your vehicle make and model.
The control arm is the metal rod that connects your wheel hub to the frame and lets your wheel move up and down while steering. When it wears out, your car pulls to one side, the steering feels loose, or you hear clunking from the front end. Replacing it is not optional — a failed control arm can cause the wheel to collapse while driving.
The total bill breaks into two parts: the part itself and the labor to install it. The part usually costs $150 to $400 per arm. Labor runs $150 to $600 per arm depending on how accessible it is on your specific vehicle. Some cars have control arms that take 45 minutes to replace; others require removing the engine subframe and take three hours.
Key Takeaways
- Most vehicles need both control arms replaced at the same time, even if only one is visibly worn, because the other is usually close behind.
- Independent repair shops typically charge 30 to 40 percent less than dealerships for the same work.
- The part cost varies widely by vehicle — a Honda Civic control arm costs far less than a BMW or truck, and aftermarket parts cost less than OEM parts.
- Labor time depends on how the control arm bolts to your specific vehicle, not on how worn it is.
Why both arms usually need replacement at once
Control arms wear at roughly the same rate on both sides because they handle the same steering and suspension stress. If one has failed or is visibly worn, the other is typically within months of the same condition. Shops often recommend replacing both because a second failure weeks after the first repair means paying labor charges twice.
Some shops will replace only the bad one if you insist, but this is usually false economy. You will likely return for the second arm within a year, paying labor a second time. The parts cost difference between one and two arms is small; the labor cost difference is not.
How the part cost breaks down by vehicle type
A control arm for a Honda Civic, Toyota Corolla, or similar compact sedan runs $150 to $250 per arm from an aftermarket supplier. The same part from the dealership (called OEM, or original equipment manufacturer) costs $250 to $350. For a truck or SUV, expect $200 to $400 from aftermarket sources and $350 to $550 from the dealership.
Luxury vehicles and European cars are significantly more expensive. A BMW or Mercedes control arm can cost $400 to $600 from aftermarket suppliers and $600 to $900 from the dealership. If your vehicle has electronic suspension or all-wheel drive, the control arm may be more complex and cost more.
Aftermarket parts are made by companies other than the original manufacturer and are usually identical in function but cost 20 to 40 percent less. OEM parts come directly from the vehicle manufacturer and carry a longer warranty. Most independent shops use aftermarket parts unless you specifically request OEM.
Labor costs at different shop types
An independent repair shop typically charges $80 to $150 per hour in labor. A control arm replacement takes 1 to 3 hours per arm depending on the vehicle. On a straightforward job, expect $150 to $300 in labor per arm. On a vehicle where the control arm is buried under other components, labor can reach $400 to $600 per arm.
A dealership charges $120 to $200 per hour and often has longer diagnostic and scheduling wait times. The same 2-hour job that costs $160 to $300 at an independent shop costs $240 to $400 at a dealership, before parts. Dealerships do have the advantage of having the exact OEM part in stock and knowing your vehicle's specific quirks.
Chain shops like Firestone or Midas fall between independent shops and dealerships in price, usually $100 to $140 per hour. They often run promotions on suspension work, so calling ahead for a quote can save money.
What affects how long the job takes
The time to replace a control arm depends almost entirely on how it bolts to your vehicle. On a Civic or Corolla, the bolts are accessible from the top and bottom, and the job takes 45 minutes to an hour per arm. On a truck with a solid front axle, the control arm may require removing the wheel, brake caliper, and axle shaft, pushing the job to 2 to 3 hours.
Some vehicles require removing the engine subframe — the metal cradle that holds the engine and suspension together — to access the control arm bolts. This adds an hour or more to the job. Your mechanic can tell you the time estimate for your specific vehicle once you describe the year, make, and model.
Signs your control arm actually needs replacement
A worn control arm usually produces one or more of these symptoms: the front end clunks or creaks when you hit a bump, the steering wheel pulls hard to one side, the car drifts when you let go of the wheel, or the inside edge of the front tire wears faster than the rest. Some vehicles also trigger a suspension warning light on the dashboard.
A mechanic can confirm a bad control arm by lifting the vehicle and grabbing the wheel at 3 and 9 o'clock, then trying to move it side to side. Excessive play means the control arm or its ball joint has failed. This is a visual inspection that takes five minutes and costs nothing at most shops.
Do not ignore these symptoms. A completely failed control arm can cause the wheel to collapse while you are driving, especially during hard cornering or braking. This is rare but dangerous.
Getting quotes from different shops
Call or visit at least two independent shops and one dealership with your vehicle's year, make, model, and current mileage. Ask for a written quote that includes the part cost, labor cost per arm, and whether they recommend replacing one or both. Ask whether they use OEM or aftermarket parts and whether you can choose.
The lowest quote is not always the best choice if the shop has poor reviews or a reputation for rushing jobs. A control arm replacement is straightforward work, but poor installation can cause steering problems or uneven tire wear later. Check online reviews and ask whether the shop offers a warranty on the work — most reputable shops offer 12 months or 12,000 miles.
If you are not sure whether you need the work done, ask the shop to show you the worn part or take a photo. A visual inspection is free and takes minutes. This protects you from paying for work you do not actually need.
Frequently Asked Questions
Can I drive with a bad control arm?
You can drive short distances to a repair shop, but not safely for long. A worn control arm causes unpredictable steering and can fail suddenly during hard cornering or braking. The longer you wait, the higher the risk of an accident or damage to other suspension parts like the tie rod or wheel bearing.
Do I really need to replace both arms at once?
Not legally, but practically yes. Both arms wear at the same rate, so the second one usually fails within months of the first. Replacing both at once means one labor charge instead of two. If budget is tight, replace the bad one now and plan to replace the other within six months.
What is the difference between OEM and aftermarket parts?
OEM parts come from the vehicle manufacturer and cost 20 to 40 percent more. Aftermarket parts are made by other companies and are functionally identical. Both carry warranties. Aftermarket parts are fine for most vehicles; OEM is worth considering only if your vehicle is luxury or has electronic suspension.
How long does the repair take?
Most control arm replacements take 1 to 3 hours per arm. A straightforward job on a sedan might be done in an hour; a truck or luxury vehicle might take 3 to 4 hours for both arms. The shop can give you an exact time estimate once they see your vehicle.
Will replacing the control arm fix my steering pull?
Usually, but not always. A steering pull can also be caused by uneven tire pressure, a bent tie rod, or a wheel alignment problem. A good mechanic will check all three before recommending control arm replacement. After replacement, you may need a wheel alignment to may support the tires wear evenly.
