Control Arm Replacement
How much does control arm replacement cost? Most drivers pay between $300 and $750, with typical labor around 2–4 hours at a local shop.
Check if your quote is fair →Control arms connect the steering knuckle to the vehicle's frame or subframe, controlling the arc of wheel travel. Most include pressed-in rubber bushings and a ball joint. When bushings crack or the ball joint wears out, handling becomes imprecise and safety is compromised.

Control Arm Replacement prices near you will vary — labor rates typically run $85–$140/hr in major metros and $65–$100/hr in smaller markets.
What your mechanic does
- Raise and support the vehicle, then remove the wheel for access
- Disconnect the ball joint from the steering knuckle using a separator tool
- Remove the control arm mounting bolts from the subframe
- Install the new control arm and torque all fasteners with the suspension at ride height
- Perform a 4-wheel alignment after replacement
Signs you need this
- Clunking or popping noise from the front suspension over bumps or during turning
- Vague or wandering steering feel
- Visible cracking or tearing in rubber control arm bushings
- Vehicle pulling to one side during normal driving
Control Arm Replacement red flags to watch for
- Replacing the entire control arm when only the bushings are worn — bushing replacement is significantly cheaper and the right fix when the arm itself is undamaged
- Not including a wheel alignment in the quoted price — alignment is mandatory after this repair and omitting it from the estimate hides the true cost
- Replacing both control arms when only one side is confirmed damaged — the other side should be inspected and quoted separately
- Using low-quality aftermarket arms with no-name bushings that wear out within a year
DIY vs. shop: control arm replacement
Advanced
Doing it yourself
Control arm replacement involves disconnecting ball joints and bushings under load — you'll need a ball joint separator, a way to support the suspension, and some patience. The job itself is mechanical but can be physically demanding.
Going to a shop
Alignment is mandatory after control arm replacement and can't be done at home without specialized equipment. Factor that cost into your comparison. Torque specs on control arm bolts are often load-dependent (tighten with suspension at ride height).
Bottom line: Doable for an experienced home mechanic with the right tools — just know you'll still need to pay for an alignment.
Frequently asked questions
How much does control arm replacement cost near me?
Control Arm Replacement costs between $300 and $750 at most shops. The exact control arm replacement price near you depends on your vehicle, local labor rates, and whether any additional parts need replacing. Use Auto Ally to check if a specific quote is fair for your ZIP code.
Can I replace just the bushing instead of the whole control arm?
Technically yes, but pressing bushings requires a hydraulic press. Since a complete control arm often costs only marginally more, most shops replace the whole assembly.
How urgent is a worn control arm?
A worn bushing can wait briefly, but a worn ball joint is a safety concern — it can separate suddenly, causing a loss of steering control. Have it inspected and repaired promptly.
Why must I get an alignment after this repair?
The control arm position sets the geometry of the wheel. Changing the arm alters camber and toe settings, requiring professional alignment equipment to reset correctly.
How do I know if my control arm needs replacing?
Worn control arm bushings cause a clunking or knocking noise over bumps, vibration in the steering wheel, and wandering or pulling during acceleration or braking. A worn ball joint on the control arm produces a similar clunk and can cause sudden loss of steering control if it separates.
Can I drive with a bad control arm?
A worn bushing can be driven on cautiously for a short time. A worn or loose ball joint should be treated as urgent — if the ball joint separates while driving, the wheel can fold under the car and you'll lose steering control completely.
How long do control arms last?
Control arms themselves often last the life of the vehicle, but the bushings and ball joints they carry typically need replacement at 80,000–150,000 miles. Road salt, off-road driving, and rough roads accelerate bushing wear significantly.
