Control arm replacement typically runs $300 to $800 per arm at a shop, or $150 to $400 in parts if you do it yourself

The total cost depends on which vehicle you own, whether you replace one arm or both, and whether the ball joint is welded or replaceable. A Honda Civic might cost $400 to $600 at a shop; a truck or luxury sedan can easily hit $1,000 or more per side. If you're doing the work yourself, you're paying for the part only — usually $150 to $300 — plus any tools you don't already own, like a ball joint separator or press.

Labor at a shop typically runs $200 to $400 per arm, depending on how long the job takes at your local rate. Some vehicles make the job straightforward; others require removing the wheel, brake components, and steering knuckle, which adds time. Getting a quote from your shop before you commit is the only way to know what you'll actually pay.

Key Takeaways

  • Shop labor ranges from $200 to $400 per arm; parts range from $150 to $300, so total cost at a shop is usually $300 to $800 per arm.
  • Luxury vehicles, trucks, and all-wheel-drive models often cost significantly more because the job takes longer or parts are more expensive.
  • If you replace one arm, the other side may wear out soon after, so shops often recommend doing both at once to avoid a second visit.
  • DIY replacement requires a ball joint separator or press, jack stands, and basic socket tools — tools you may need to rent or buy.
  • Dealership pricing is typically 20 to 40 percent higher than independent shops for the same work.

What the parts themselves cost

A replacement control arm runs $150 to $300 from an auto parts store or online retailer, depending on the vehicle. Economy cars and common models like Civics and Corollas sit at the lower end; trucks, SUVs, and European brands cost more. Some vehicles use a single-piece arm with the ball joint already attached; others use a separate ball joint that you install yourself, which can save $50 to $100.

OEM (original equipment manufacturer) parts from the dealership cost 30 to 50 percent more than aftermarket equivalents. A Civic control arm from Honda might be $250; the same part from an aftermarket supplier might be $120. Both work, though OEM parts come with a longer warranty. If you're doing the work yourself, aftermarket is the standard choice.

Check the part number against your vehicle's year, make, model, and engine size before ordering. A wrong part will not fit, and returns can take weeks. Most online retailers let you enter your VIN and show you the correct part automatically.

Labor costs at independent shops versus dealerships

An independent mechanic typically charges $200 to $350 per arm in labor, based on a flat rate or hourly rate (usually $80 to $150 per hour). The job usually takes 1 to 2 hours per arm, depending on how accessible it is on your vehicle. Some shops charge a flat rate for the job; others charge by the hour. Ask which method they use before you commit.

Dealerships charge $250 to $400 per arm in labor, sometimes more. They use OEM parts by default, which adds to the total bill. A dealership control arm replacement that costs $600 at an independent shop might cost $900 to $1,100 at the dealer — not because the work is better, but because the parts and labor rates are higher. Dealerships are worth considering only if your vehicle is under warranty or if the independent shops in your area have long wait times.

Why shops recommend replacing both arms at once

If one control arm is worn enough to need replacement, the other side is usually close behind. Both arms wear at similar rates because they experience the same road conditions and mileage. Replacing only one arm means you'll likely be back in a few months or a year for the other side, paying labor costs twice.

Shops often recommend doing both at once to save you money in the long run and to avoid a second service visit. If you're on a tight budget, replacing one is fine — the car will drive safely — but budget for the second arm sooner rather than later. Some shops offer a small discount if you do both at the same time, so ask.

Tools and equipment you'll need for DIY replacement

At minimum, you need a jack, jack stands, a socket set, a ball joint separator (or a way to press the ball joint out), and a torque wrench. The ball joint separator is the tool most people don't own; it costs $30 to $60 to buy or $10 to $20 to rent from an auto parts store. A press can also remove the ball joint, but that usually means a trip to a shop with a hydraulic press.

You'll also need safety glasses, a work light, and patience. The bolts holding the arm in place are often tight, and the ball joint can be stubborn to separate from the steering knuckle. Penetrating oil (like PB Blaster) applied the night before makes the job easier. If you've never done suspension work, budget extra time — the job can take 3 to 4 hours per arm if you're moving slowly and checking your work.

Some vehicles make this job harder than others. Front-wheel-drive cars are usually straightforward; all-wheel-drive vehicles and trucks sometimes require removing additional components. Check a repair manual or YouTube video for your specific vehicle before you start, so you know what you're getting into.

When to replace control arms and what triggers the cost

A worn control arm usually shows up as a clunking noise from the front end when you hit bumps, or as uneven tire wear. Your mechanic may spot it during an inspection and recommend replacement. Some vehicles wear them out faster than others — rough roads, potholes, and aggressive driving all accelerate wear.

If you ignore a bad control arm, the steering knuckle can move excessively, which damages the ball joint, wheel bearing, and tie rod. That turns a $400 repair into a $1,000 repair. Getting it done sooner rather than later is cheaper in the long run. If your mechanic recommends it, the cost is worth paying to avoid bigger problems down the road.

Frequently Asked Questions

Can I drive with a bad control arm?

You can drive short distances, but it's not safe for regular use. A worn control arm causes loose steering, uneven tire wear, and clunking noises. The longer you wait, the more damage spreads to the ball joint and wheel bearing, which makes the repair more expensive. Have it inspected by a mechanic and replaced soon.

Do I need to replace the ball joint too?

Not always. If the ball joint is separate from the control arm and still in good condition, you can reuse it. If it's welded to the arm or visibly worn, replace it at the same time. Your mechanic can tell you during the job. Replacing both together costs a bit more but saves you from coming back later.

How long does control arm replacement take at a shop?

Most shops complete one arm in 1 to 2 hours. If you're doing both arms, expect 2 to 4 hours total. Some vehicles are faster; others take longer because of how the suspension is designed. Ask your shop for an estimate before they start work so you know when to expect your car back.

Is an aftermarket control arm as good as OEM?

Yes, for most vehicles. Aftermarket parts meet the same safety standards and come with a warranty. They cost less because the manufacturer doesn't have the brand markup that OEM parts carry. OEM parts are worth considering only if your vehicle is under warranty or if you want the longest possible warranty on the replacement part.

What if I only replace one control arm?

The car will drive safely, but the other arm will likely wear out within months or a year. You'll end up paying labor costs twice. If budget is tight, replacing one is acceptable, but plan to do the other side soon. Some shops offer a discount if you return within a certain timeframe to do the second arm.
