Is It Safe to Drive With a Bad Stabilizer (Sway) Bar?
You can usually drive a short distance at low speeds with a bad or disconnected stabilizer (sway) bar, but it is risky and not recommended. Handling will be compromised, especially in turns or emergency maneuvers. Avoid highways and fix the issue as soon as possible to prevent loss of control and potential secondary damage.

What the Stabilizer Bar Does—and Why It Matters
The stabilizer bar, also called a sway bar or anti-roll bar, links the left and right sides of your suspension. Its job is to reduce body roll in corners, keeping the vehicle flatter and the tires more evenly loaded. When the bar, its bushings, or end links fail, your vehicle’s ability to corner predictably and maintain traction declines—most noticeably during quick lane changes, off-ramps, or evasive maneuvers.
Is It Safe to Drive With a Bad Stabilizer Bar?
In everyday, low-speed conditions on straight roads, many vehicles will still move without immediate catastrophe if a stabilizer bar or link fails. However, safety margins shrink dramatically when you need to turn sharply, brake while turning, or navigate uneven pavement. The risk is higher for taller vehicles (SUVs, vans, pickups) due to a higher center of gravity. Stability control systems can help but cannot fully compensate for a missing or ineffective sway bar.
How Risk Changes by Situation
Driving with a compromised stabilizer bar becomes more dangerous as speed, load, and cornering forces increase. That means freeway ramps, high-speed lane changes, mountain roads, towing, and wet or icy conditions are particularly hazardous.
Common Signs Your Stabilizer Bar or Links Are Failing
Watch for these practical indicators before the problem escalates. Identifying them early can help you avoid unsafe driving conditions and reduce repair costs.
- Clunking or knocking over bumps, especially from the front suspension
- Excessive body roll or “floaty” feeling in turns
- Loose, imprecise steering or sudden understeer/oversteer
- Visibly broken or dangling sway bar link(s)
- Cracked, worn, or missing sway bar bushings
- Uneven tire contact sensation on bumpy corners
If you notice one or more of these symptoms, reduce speed, avoid aggressive driving, and schedule an inspection promptly. Early repairs often involve inexpensive parts like bushings or links.
What Can Go Wrong If You Keep Driving
Continuing to drive with a bad stabilizer bar or links increases safety risks and can lead to additional wear or damage. Here’s what you could face.
- Loss of stability in turns, increasing the chance of skids or spin-outs
- Longer, less controlled stopping during turning/braking combinations
- Higher rollover risk in tall vehicles during abrupt maneuvers
- Potential secondary damage from a loose link or bar striking nearby components
- Failure of safety inspections; possible insurance scrutiny after a crash
While not all failures cause immediate mechanical breakdown, the reduced control can turn routine situations into emergencies—especially at speed.
If You Must Drive Before Repair
Sometimes you need to reach a shop. If driving is unavoidable, take deliberate steps to reduce risk during the short trip.
- Keep speeds low and increase following distance
- Avoid highways, sharp turns, and sudden lane changes
- Minimize load and roof cargo; ask passengers to sit centrally and low
- Choose the flattest, smoothest route possible
- Check tire pressures and ensure other suspension components are intact
- Be gentle with steering, braking, and throttle inputs
These precautions do not make the drive “safe,” but they can help you reach a service facility with reduced risk.
Repair Options, Time, and Typical Costs
Most stabilizer bar issues involve worn bushings or broken end links, both of which are relatively straightforward fixes compared with major suspension work.
- Sway bar end links: $20–$100 each (parts); 0.5–1.0 labor hour per side
- Sway bar bushings: $10–$50 (parts); 0.5–1.5 labor hours
- Complete sway bar replacement: $150–$600 (parts); 1–3 labor hours
- Labor rates vary widely by region; expect roughly $75–$175 per hour
Most shops can complete link or bushing replacements the same day. Replacing the bar itself takes longer but is still a routine job on many vehicles. Ask for torque-to-spec on fasteners and an inspection of adjacent components.
DIY Considerations
DIY is feasible for experienced home mechanics with proper tools, rust-penetrant, and safe lifting equipment. Always support the vehicle correctly and follow torque specifications; suspension fasteners are critical for safety.
Inspection and Legal Notes
In regions with periodic safety inspections, broken sway bar links or bushings typically result in a fail. While it’s generally not illegal to drive to a repair shop, knowingly operating a vehicle with a safety-related defect can raise liability issues after a collision. Document your repair appointment if you must drive.
Bottom Line
Driving with a bad stabilizer bar is possible but unsafe—particularly at higher speeds or in emergency situations. Limit any driving to a short, low-speed trip to a repair facility, and address the issue promptly to restore proper handling and safety margins.
Summary
A failing stabilizer bar or its components undermines vehicle stability, especially in turns. You can often nurse the car at low speeds for a short distance, but it’s not advisable beyond reaching a shop. Look for clunks, excess body roll, and loose steering; replace worn links or bushings promptly. Repairs are typically quick and moderately priced, restoring the predictable handling your vehicle’s safety systems expect.
How long can you drive with a bad sway bar?
You can drive with a bad sway bar, but it is not recommended for any extended period, especially if you can’t avoid high-speed driving or aggressive maneuvers. While your car might remain driveable, a bad sway bar significantly reduces vehicle stability, increasing body roll in turns and making the handling feel “looser”. This compromised handling, particularly in the front, can lead to a loss of control in emergency situations, putting you and other drivers at risk.
Why a bad sway bar is a safety risk
- Increased body roll: Sway bars (or anti-roll bars) are designed to prevent the car’s body from leaning excessively during turns. A bad or broken sway bar allows for more body roll, making the car feel less stable.
- Compromised handling: With a broken sway bar, the suspension’s ability to manage body weight during cornering is significantly reduced. This can lead to vague steering and unpredictable handling.
- Risk of loss of control: While a car might still be drivable with a broken sway bar, you can’t predict when you might need to perform an evasive maneuver. A broken sway bar increases the risk of losing control, especially on highways or at high speeds.
What to do if you have a bad sway bar
- Drive slowly and cautiously: If you must drive with a bad sway bar, significantly reduce your speed and avoid aggressive steering or hard braking.
- Stick to surface streets: Stay off highways and interstates where you may need to change lanes or handle higher speeds.
- Get it replaced ASAP: A bad sway bar is a serious safety issue. Have the faulty sway bar or sway bar links inspected and replaced by a mechanic as soon as possible.
How much does it cost to fix a stabilizer bar?
The average cost for a Stabilizer Bar Link Kit Replacement is between $125 and $186. Labor costs are estimated between $62 and $91 while parts are priced between $63 and $96. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
Can I drive my car without a stabilizer bar?
Yes, you can drive a vehicle without a stabilizer bar (also known as a sway bar), but it is not recommended for normal driving because it significantly worsens handling and makes the vehicle much less stable, leading to increased body roll, unpredictable handling, and reduced traction. You should only do so in an emergency or for short distances, driving extremely slowly and cautiously, especially when cornering or changing lanes.
Why Driving Without a Stabilizer Bar Is Risky
- Increased Body Roll: The primary function of a sway bar is to reduce the amount your car leans or “rolls” when turning. Without it, the car will lean much more, making it feel unstable.
- Reduced Traction: The uneven suspension movement caused by a lack of a sway bar can lead to reduced traction, particularly when turning.
- Unpredictable Handling: Driving without a stabilizer bar makes the vehicle harder to control, especially in quick maneuvers, potentially leading to understeer (the car doesn’t turn enough) or oversteer (the rear of the car slides out).
- Safety Hazard: The instability and potential for sudden loss of control make it dangerous to drive a car without a stabilizer bar, particularly on high-speed roads or in emergencies.
When You Might Drive Without One
- Emergency Situation: In an absolute emergency, you may need to drive a short distance to safety, but you must proceed with extreme caution.
- Off-Roading: Some off-road enthusiasts disconnect their sway bars for greater wheel articulation (flex). However, they are typically limited to low-speed off-road use only and are reconnected for road travel.
In summary, while technically possible, driving without a stabilizer bar is a significant safety risk that should be avoided whenever possible.
What happens if the stabilizer bar breaks while driving?
Reduced Handling and Stability: The sway bar (or stabilizer bar) helps reduce body roll during cornering. A broken link can lead to increased body roll, making the vehicle feel less stable and harder to control, especially during turns.
