# Control arm replacement cost - **Typical cost:** $300-$850 per arm - **Parts:** $80-$400 - **Labor:** 1-3 hours per arm plus alignment - **Dealer:** $500-$1,200 ## Quick answer Replacing one control arm usually costs $300 to $850 at an independent shop, including the alignment most shops recommend afterward. A stamped-steel lower arm on a compact car is at the low end. Aluminum arms on luxury cars and multi-link suspensions, and large truck arms, cost the most. ## What is control arm and why does it need replacing? Control arms are the hinged links that connect each wheel's steering knuckle or hub carrier to the car's frame or subframe. Rubber bushings at the frame end let the arm pivot up and down as the suspension moves, and a ball joint at the wheel end lets the wheel steer. Most front suspensions have a lower control arm on each side, and many also have an upper arm. Multi-link designs use several smaller arms at each corner. Control arms rarely wear out as metal parts. What fails is usually the bushings or the ball joint built into the arm. Rubber bushings crack, tear and soften with age, heat, oil leaks and road salt, which lets the arm shift and changes the alignment. On many newer cars the ball joint is pressed or riveted into the arm and is not sold separately, so a worn joint means a new arm. A pothole or curb strike can also bend an arm outright. Many arms and bushings last 90,000 miles or more, but rough roads shorten that. ## How much does control arm replacement cost? | | Typical cost per arm | | --- | --- | | Parts | $80-$400 | | Labor | $200-$450 (1-3 hours per arm plus alignment) | | Total at an independent shop | $300-$850 | | Total at a dealer | $500-$1,200 | | Do it yourself (parts only) | $80-$400 | ## Cost by vehicle type | Vehicle | Typical cost per arm | | --- | --- | | Compact car | $300-$500 | | Midsize sedan | $320-$550 | | Small SUV/crossover | $350-$600 | | Full-size truck/SUV | $400-$750 | | Luxury/European | $500-$850 | Ranges are for an independent shop. Expect the high end or more for European luxury makes and dealer service. ## What changes the price? - **Arm design and material.** Stamped-steel arms on economy cars are the cheapest. Forged or cast aluminum arms on luxury and performance cars, and heavy truck arms, cost more, and some come only as complete assemblies from the carmaker. - **Arm or bushings only.** Some shops can press new bushings into the old arm, which saves on parts but takes more labor. A complete arm with new bushings and ball joint often costs about the same installed and leaves no worn parts. - **Upper, lower or multi-link.** Lower arms carry most of the load and usually wear first. Multi-link rear and front suspensions have several arms per corner, and a shop may recommend replacing more than one at a time. - **Rust and seized bolts.** Control arm bolts often pass through rubber bushings with steel sleeves that rust to the bolt. In road-salt states, seized bolts may need to be cut out, which adds labor and new hardware. - **Wheel alignment.** A new control arm changes the camber, caster or toe, so most shops require or strongly recommend an alignment, which adds about $100 to $200. Doing both sides together means paying for one alignment. ## Can you do it yourself? Difficulty: **Moderate**, about 2-3 hours per arm. Parts cost $80-$400, so doing it yourself saves the labor ($200-$450). ## What happens during the job? 1. Lift the car and check the control arm bushings and ball joint for cracks, tears and play with a pry bar. 2. Remove the wheel, disconnect the sway bar link and any sensor wiring, and separate the ball joint from the knuckle. 3. Unbolt the arm from the subframe or frame, cutting seized bolts if needed, and remove it. 4. Install the new arm, connect the ball joint and other parts, and tighten the bushing bolts with the suspension at ride height. 5. Refit the wheel, perform a wheel alignment and road-test for noise, pulling and steering feel. ## What should a fair quote include? - New control arm with bushings and ball joint if integrated - New mounting bolts and nuts where one-time-use - Torquing bushing bolts with the suspension at ride height - Wheel alignment - Inspection of the other side and nearby suspension parts ## How to pay less for control arm replacement - Ask for the worn bushing or joint to be shown to you so you know the arm truly needs replacing. - Replace both lower arms together if both are worn, so you pay for one alignment instead of two. - Choose a quality aftermarket arm with a warranty rather than the cheapest option or a dealer part. - On cars with separate ball joints and bushings, compare the cost of replacing only the worn piece. - Fix oil leaks that drip onto suspension bushings, since oil softens the rubber. ## Signs you need it - Clunk or knock over bumps or when braking - Steering wanders or pulls to one side - Steering wheel vibration or shimmy - Uneven tire wear on one edge - Cracked, torn or bulging rubber bushings - Car shifts or clunks when you brake hard ## Which models get the most suspension complaints? | Model | Suspension complaints to NHTSA | All complaints | | --- | --- | --- | | [Jeep Wrangler](/vehicles/jeep-wrangler) | 840 | 6,195 | | [Tesla Model 3](/vehicles/tesla-model-3) | 376 | 4,252 | | [Ford Explorer](/vehicles/ford-explorer) | 333 | 9,238 | | [Jeep Grand Cherokee](/vehicles/jeep-grand-cherokee) | 268 | 5,477 | | [Ram 1500](/vehicles/ram-1500) | 252 | 7,390 | | [Chevrolet Silverado](/vehicles/chevrolet-silverado) | 181 | 7,658 | | [Subaru Forester](/vehicles/subaru-forester) | 124 | 4,113 | | [Jeep Cherokee](/vehicles/jeep-cherokee) | 110 | 7,486 | | [Nissan Altima](/vehicles/nissan-altima) | 110 | 2,717 | | [GMC Sierra](/vehicles/gmc-sierra) | 91 | 5,041 | Owner complaints filed with NHTSA in the suspension category for 2015-2026 models of 63 popular cars.

Most independent shops charge $300 to $850 per arm in 2026, including the alignment, and dealers $500 to $1,200. A steel lower arm on a compact car is at the low end. Aluminum arms on luxury cars and large truck arms cost the most. Doing both sides shares one alignment. ### Can I drive with a bad control arm? For a short time with worn bushings, but it is not safe to ignore. A loose arm or worn ball joint can make the steering wander, the car shift when braking and the tires wear fast. A bent arm or a ball joint with heavy play needs attention right away. ### How do I know if my control arm is bad? Common signs are clunks over bumps or when braking, steering that wanders or pulls, a steering wheel shimmy and uneven tire wear. A shop lifts the car and checks the bushings for tears and the ball joint for play. A visibly bent arm after a pothole is also a clear sign. ### Should I replace control arms in pairs? Often yes, if both are worn. Arms on the same axle have the same miles and loads, so the other side is usually close behind. Replacing both at once avoids paying for a second alignment, but a single arm bent in a pothole can be replaced on its own. ### Do I need an alignment after replacing a control arm? Yes, in almost all cases. The control arm helps set the wheel's camber, caster and toe, and even a small change can make the car pull or wear tires quickly. Most shops include an alignment in the quote, and it typically adds $100 to $200. ### Is it cheaper to replace bushings or the whole arm? Bushings are cheaper as parts, but pressing them in takes more labor. A complete arm often costs about the same installed and also includes a new ball joint. On cars with integrated joints, the whole arm is usually the better value, so ask the shop for both prices. ### How long does it take to replace a control arm? Most shops need about 1 to 3 hours per arm, plus about an hour for the alignment. Rusted or seized bolts and multi-link suspensions add time. Replacing both front lower arms is often finished in half a day, and most shops can do it without keeping the car overnight. ### Can I replace a control arm myself? On many cars, yes, if you have a jack, stands, a ball joint separator and a torque wrench. Tighten the bushing bolts with the suspension at ride height to avoid tearing the new bushings. You still need a professional alignment afterward, so plan to drive straight to a shop. ### What causes control arm bushings to wear out? Age, heat, road salt and oil leaks harden and crack the rubber over time. Potholes, curb strikes, heavy loads and rough roads add stress. As the bushings soften, the arm moves more than it should, which causes clunks, alignment changes and uneven tire wear. ### Will a bad control arm fail inspection? In states with safety inspections, a control arm with torn bushings or a loose ball joint can fail. Inspectors check for excess play and visible damage in the front suspension. Even where there is no inspection, a worn arm affects steering and braking, so it is worth fixing. ## Sources - [Car Care Council: Car care guide](https://www.carcare.org/car-care-guide/) - [AAA: Approved Auto Repair](https://www.aaa.com/autorepair/) - [ASE: National Institute for Automotive Service Excellence](https://www.ase.com/) ## How long it lasts - [How often do you need a wheel alignment?](https://diagxcar.com/how-often/get-wheel-alignment): Check every 1-2 years ## Symptoms - [Why does my car pull to one side?](https://diagxcar.com/symptoms/car-pulls-to-one-side) - [What causes uneven tire wear?](https://diagxcar.com/symptoms/uneven-tire-wear) - [Why does my steering wheel shake at high speeds?](https://diagxcar.com/symptoms/steering-wheel-shakes-at-high-speed) - [Why does my car shake when I brake?](https://diagxcar.com/symptoms/car-shakes-when-braking) ## Other repair costs - [Coolant flush cost](https://diagxcar.com/cost/coolant-flush): $110-$260 - [Clutch replacement cost](https://diagxcar.com/cost/clutch-replacement): $1,000-$2,500 - [Crankshaft position sensor replacement cost](https://diagxcar.com/cost/crankshaft-position-sensor-replacement): $150-$500 - [Catalytic converter replacement cost](https://diagxcar.com/cost/catalytic-converter-replacement): $1,000-$3,000 - [CV axle replacement cost](https://diagxcar.com/cost/cv-axle-replacement): $250-$700 - [Car battery replacement cost](https://diagxcar.com/cost/car-battery-replacement): $150-$450 - [EGR valve replacement cost](https://diagxcar.com/cost/egr-valve-replacement): $250-$850 - [Camshaft position sensor replacement cost](https://diagxcar.com/cost/camshaft-position-sensor-replacement): $120-$350 - [Engine replacement cost](https://diagxcar.com/cost/engine-replacement): $4,000-$12,000 - [Brake rotor replacement cost](https://diagxcar.com/cost/brake-rotor-replacement): $300-$800 --- Source page: https://diagxcar.com/cost/control-arm-replacement Updated: 2026-11-03 General information, not a substitute for a qualified mechanic.
