What are the symptoms of bad ball joints?
Common symptoms of a bad ball joint include a clunking noise over bumps, a loose or wandering steering feel, and uneven tire wear. These signs suggest the suspension is not functioning as designed and should be evaluated promptly to avoid safety risks.
Ball joints connect the steering knuckle to the control arms and serve as pivot points for wheel movement. When they wear, you can experience noise, steering instability, and irregular tire wear. This article reviews the key symptoms, explains why they occur, and outlines the steps to take if you notice them.
Common symptoms motorists notice
The following signs are the most frequently reported indicators of a worn ball joint. While some symptoms may overlap with other suspension issues, ball joints remain a common failure point in many vehicles.
- Clunking or banging noise when driving over potholes, speed bumps, or rough pavement
- Squeaking, creaking, or grinding sounds when turning
- Loose, wandering, or imprecise steering; the vehicle may pull to one side
- Uneven or accelerated tire wear, especially on the inner or outer edges
- Excessive play or wobble in the wheel when inspected by a technician
- Vibration or shakiness in the steering wheel, more noticeable at highway speeds
- Visible damage to the ball joint boot (cracks or tears) or grease leakage around the joint
Noting any of these symptoms should prompt a professional inspection. A failing ball joint can compromise steering control and ultimately lead to more extensive suspension damage if left untreated.
What to do if you notice symptoms
Because ball joints work in concert with other suspension components, a mechanic will typically perform a visual inspection, check for play, and assess alignment and tire wear to confirm the diagnosis. If wear is confirmed, replacement of the ball joints is often recommended to restore proper handling and safety.
Some vehicles use sealed, pressed-in ball joints that require specialized tools for replacement. Driving with a bad ball joint can create unpredictable handling and increase the risk of a failure that could affect control of the vehicle.
Summary
Worn ball joints typically reveal themselves through noises, steering changes, and tire wear. If you notice clunks, a wandering steering feel, or unusual tire wear, schedule a professional inspection promptly. Replacing worn ball joints helps preserve steering performance and overall vehicle safety.
How much does it cost to fix ball joints?
The average cost to replace a single ball joint is between $250 and $500, which includes parts and labor. However, the total cost can vary significantly, from around $175 to over $1,750, depending on the vehicle, if the ball joint is integrated into a control arm, and whether it's a two-part (front and rear) replacement. Parts typically cost between $20 and $150, while labor can be $80 to $200 per hour, with the total job taking one to three hours.

Cost breakdown
- Parts: $20 to $150 per ball joint, but higher for OEM or branded parts.
- Labor: $80 to $200 per hour, with a total job taking 1 to 3 hours.
- Total (single ball joint): $250 to $500 for most mainstream vehicles.
- Total (twin replacement): $400 to $750, as it's common to replace both sides at once.
- Control arm replacement: If the ball joint is integrated into the control arm, the cost can jump to $600 to $750 for that part alone.
- Wheel alignment: A recommended $100 to $150 alignment after replacement is usually not included in the initial quote.
Factors that can increase the cost
- Integrated ball joints: Some modern designs require replacing the entire control arm assembly, which is more expensive than replacing just the ball joint.
- Vehicle type: European or sports cars can have higher parts and labor costs.
- Shop: Dealerships will likely have higher labor rates than independent shops.

What to do
- Get multiple quotes: Get quotes from different mechanics, as prices can vary significantly.
- Check the quote breakdown: Ensure the quote separates parts, labor, and the optional alignment.
- Consider DIY: If you're handy, replacing ball joints can be a DIY project, but it requires special tools and is often best left to professionals unless you have prior experience.
Can you drive with a bad ball joint?
No, you cannot and should not drive with a bad ball joint because it is a critical safety component and its failure can lead to a complete loss of steering control, serious accidents, and catastrophic failure where the wheel could come off. If you suspect a bad ball joint, avoid driving the vehicle and have it replaced immediately by a professional.
Risks of driving with a bad ball joint
- Loss of steering control: A failed ball joint can cause you to lose control of the vehicle, especially during turns or when hitting a bump.
- Catastrophic failure: A complete failure can cause the wheel to lean dramatically, and in a worst-case scenario, the wheel could detach from the vehicle.
- Further damage: Driving on a bad ball joint will cause more damage to other suspension and steering components, leading to higher repair costs.
- Accidents: The combination of lost control and potential for wheel detachment puts you and others at a high risk of a serious accident, potentially a rollover.
What to do if you have a bad ball joint
- Do not drive: As soon as you notice symptoms like clunking noises, shaky steering, or uneven tire wear, do not drive the vehicle.
- Tow the vehicle: Have the car towed to a mechanic for a professional inspection and repair.
- Get the ball joint replaced: A qualified mechanic needs to replace the worn ball joint to restore the safety and integrity of the suspension.
Is replacing ball joints a big job?
Replacing ball joints is an intermediate-to-big job that can range from manageable to very difficult depending on the vehicle and its condition. The difficulty depends on factors like the type of ball joint (press-in vs. bolt-on), accessibility, and if the parts are seized by rust. It's often recommended for those with experience and the right tools, or for a professional mechanic.

Factors that make it a bigger job
- Vehicle condition: Rust and age can make it difficult to remove seized ball joints, potentially increasing the time and effort needed significantly.
- Ball joint type: Bolt-on ball joints are easier to replace than press-in ball joints, which require a special ball joint press tool.
- Accessibility: On some vehicles, ball joints are in hard-to-reach locations, making the job more time-consuming.
- Integration with other parts: On some cars, the ball joint is integrated into the control arm, meaning the entire assembly must be replaced.

DIY vs. Professional
- DIY: You can tackle this job yourself if you have mechanical experience and the proper tools, such as a ball joint press and an impact wrench. Be prepared for it to take several hours, especially if it's your first time.
- Professional: It is highly recommended to have a professional perform the replacement if you are unfamiliar with suspension work or lack the necessary tools. A professional can also check the entire suspension system and ensure the work is done correctly. A final wheel alignment is often needed after the ball joints are replaced.

How do you know if your ball joints are bad?
Clunking Noises
One of the most common symptoms of a failing ball joint is a clunking or knocking noise from the front suspension, particularly when going over bumps or making turns. The sound occurs because a worn ball joint will have a lot of play, allowing the suspension to knock metal against metal.
