Can you drive a car with a bad sway bar?
No—driving a car with a bad sway bar is unsafe. The stabilizer bar helps limit body roll in corners, and when it’s damaged, handling can become unpredictable, increasing the risk of loss of control. If you suspect a problem, arrange a professional inspection and repair as soon as possible.
What a sway bar does
The stabilizer bar, or sway bar, links the left and right sides of the suspension to help equalize roll forces when the vehicle cornering. It works with springs and shocks to minimize body lean, improve steering feel, and keep tires in contact with the road during turns.
Core components
The following list outlines the main parts involved in a sway bar system. Understanding them helps explain how failure can affect handling.
- Sway bar (stabilizer bar) itself
- End links that connect the bar to the suspension
- Bushings that mount the bar to the chassis
- Mounting brackets and bolts
- Fasteners and related hardware
Problems with any of these parts can reduce effectiveness or cause the bar to separate from the vehicle, affecting handling especially during cornering or over irregular surfaces.
Safety implications and driving implications
Damage to the sway bar alters how the car behaves in corners and during quick lane changes. Even a degraded bar can make the car feel unstable, increase body roll, and prolong stopping distances in emergency maneuvers. Warning signs may appear gradually or suddenly, depending on the damage.
- Excessive body roll when turning or changing lanes
- Clunking, banging, or squeaking noises from the suspension, especially over bumps
- Visible damage or looseness in end links, bushings, or mounting points
- Uneven or accelerated tire wear due to altered suspension geometry
When these symptoms are present, driving at speed or in demanding conditions is risky, and a professional inspection is advised before continuing to drive.
Should you drive now? Steps to take
To minimize risk, follow these precautions. Do not travel long distances or drive aggressively until a qualified mechanic has inspected and repaired the system.
- If symptoms are present, limit driving to a safe, slow speed and avoid corners, ramps, or uneven surfaces as much as possible.
- Plan to have the vehicle towed or transported to a repair facility rather than attempting a long drive.
- Visually inspect only if safe to do so; look for obvious signs such as a broken link or loose mounting hardware, but avoid reaching under moving parts.
- Schedule service promptly with a qualified technician; inform them of the suspected sway-bar issue so they can plan the inspection.
These steps prioritize safety while ensuring the vehicle is repaired correctly and efficiently.
Repair options and estimated costs
Replacement is typically straightforward, but costs vary based on vehicle make, whether parts are front or rear, and local labor rates. The following are common options and rough price ranges as of 2024–2025.
- Sway bar end links replacement (front or rear): parts roughly $20–$120; labor $50–$150
- Sway bar bushings replacement (with mounts or brackets as needed): parts roughly $20–$60; labor $50–$150
- Sway bar assembly replacement (if bar itself is bent or severely damaged): parts roughly $40–$250; labor $100–$250
- Additional costs to consider: wheel alignment is not always required, but tire inspection and road test may add to the labor time
For some vehicles, especially modern or high-performance models, replacing multiple components or both front and rear sway bars may be necessary, which increases total cost and downtime.
Summary
A functioning sway bar is a key part of a vehicle's stability in turns. A bad sway bar can compromise handling, increase body roll, and raise the risk of loss of control, particularly at speed or in emergency maneuvers. If you notice symptoms or suspect a problem, avoid driving aggressively, and seek an inspection and repair promptly. Addressing the issue typically involves replacing end links and bushings, and, in more severe cases, the bar itself, with costs varying by vehicle and region.
How bad is it to drive with a bad sway bar?
Yes, it can be dangerous to drive with a bad sway bar because it compromises your vehicle's stability and handling, especially during turns or sudden maneuvers. While you may still be able to drive slowly, you risk losing control, causing an accident, or potentially damaging other suspension components.

Safety risks of a bad sway bar
- Reduced stability: A bad sway bar, particularly a broken link, reduces the vehicle's ability to resist body roll, making it feel wobbly and unstable, especially at higher speeds.
- Poor handling: Your car will lean more in corners, and steering may feel less precise or delayed.
- Emergency maneuver issues: In an emergency, you could lose control during a sudden lane change or swerve due to decreased traction.
- Risk of further damage: A broken or loose sway bar can shift and get lodged in other parts of the suspension or even damage tires.
- Potential for catastrophic failure: If a sway bar link breaks completely, it can lead to more significant issues or even a catastrophic failure of the suspension system.
What to do if you have a bad sway bar
- Drive cautiously: If you must drive, do so at a slower speed and avoid highways or sudden movements. Stick to surface streets and drive very gently.
- Avoid sharp turns: Take turns much slower than you normally would to minimize the effect of the sway bar's failure.
- Get it inspected immediately: Have a mechanic inspect the sway bar system as soon as possible and replace the necessary parts to restore your vehicle's handling and safety.

How much is it to replace a sway bar on a car?
The cost to replace a sway bar typically ranges from $150 to $650, but it can be higher depending on the vehicle and the specific parts needed. Replacing just the sway bar end links or bushings is often less expensive, while a full sway bar replacement can push the cost over $1,000 on certain vehicles, especially if the subframe needs to be lowered or special systems are involved.
Cost breakdown
- Sway bar end links or bushings: These are the most common replacements and are typically the cheapest option.
- Total cost: $150 to $500 per axle.
- Parts: $20 to $100.
- Labor: $70 to $100 per hour, making up the majority of the cost.
- Entire sway bar replacement: This is a more extensive and costly job.
- Total cost: $200 to over $1,000.
- Higher costs: May occur on vehicles with complex or active anti-roll systems (like some Land Rovers or Mercedes) or those requiring the subframe to be removed for access.
Factors that influence cost
- Vehicle make and model: Labor and part prices vary significantly between different vehicles. Exotic or luxury cars will often be more expensive.
- Parts needed: The cost depends on whether only bushings or end links are needed, or if the entire bar needs to be replaced.
- Labor rates: The cost of labor varies by shop, with dealerships typically being more expensive.
- DIY vs. professional installation: If you are mechanically inclined, you can save significantly on labor costs by replacing the end links or bushings yourself, as they are often a relatively simple job with the right tools.
How long can you drive with a broken sway bar?
If your vehicle is primarily used for short, low-speed trips, you might get away with driving for a while. However, for longer commutes or high-speed driving, you should prioritize replacing the bad links as soon as possible to avoid safety risks and further damage.
How urgent are sway bar links?
If you notice loose or broken sway bar links, replacing them as soon as possible is crucial to preventing further damage to the suspension system.
