Ball Joint Replacement Cost

Average Cost

• Single ball joint replacement: $200–$450
• Both front ball joints (common to do together): $350–$700
• Control arm with integrated ball joint: $400–$800 per side
• Alignment required after replacement: $100–$175 additional

Symptoms of Worn Ball Joints

• Clunking or knocking noise from front suspension over bumps
• Steering wander or pulling to one side
• Uneven tire wear
• Vibration in the steering wheel
• Excessive play felt when lifting the wheel and checking for movement
• Squeaking from front suspension when going over speed bumps (early stage)

How Dangerous Are Bad Ball Joints?

A worn ball joint can separate from the control arm while driving, causing the wheel to collapse inward or outward. This results in an immediate loss of steering control. Ball joint failure at highway speeds is life-threatening. If a shop tells you a ball joint is worn, take it seriously — this is not a repair to defer.

Upper vs. Lower Ball Joints

Most vehicles have lower ball joints that bear the vehicle's weight (load-bearing) — these wear faster. Upper ball joints are present on double-wishbone suspensions and wear more slowly. MacPherson strut suspensions (most front-wheel-drive cars) only have lower ball joints. Always replace in pairs on the same axle if one is worn — the other is likely close behind.

Ball Joint vs. Control Arm

On some vehicles the ball joint is pressed into the control arm and must be replaced as an assembly — this costs more but is sometimes the only option. On others, the ball joint is a separate serviceable component. A shop can tell you which applies to your vehicle. For high-mileage vehicles, replacing the whole control arm is often recommended since the bushings wear at the same rate.
