Can I drive if my CV axle is bad?

No, it is generally not recommended to drive a vehicle if the constant velocity (CV) axle is bad or damaged. A faulty CV axle can pose serious safety risks and lead to further damage to your vehicle if driven in that condition.


What is a CV Axle?

A CV axle, also known as a constant-velocity joint, is a critical component in the drivetrain of a vehicle. It connects the wheel hub to the differential or transmission, allowing the wheels to rotate at different speeds while the vehicle turns. The CV axle enables smooth power transfer and allows the wheels to move up and down independently, providing a comfortable ride.


Signs of a Bad CV Axle

  • Clicking or popping noises: A damaged CV axle will often produce audible clicking, popping, or clunking sounds, especially when turning or accelerating.

  • Vibrations: A worn CV axle can cause noticeable vibrations in the steering wheel or throughout the vehicle.

  • Grease leaks: If the CV axle boot (the protective cover) is cracked or damaged, the grease inside can leak out, leading to further damage.

  • Difficulty turning: A bad CV axle can make it harder to steer the vehicle, especially at low speeds or when turning.


If you notice any of these signs, it's important to have your CV axle inspected and repaired as soon as possible to avoid further damage and ensure safe driving.


Risks of Driving with a Bad CV Axle

Driving with a bad CV axle can be extremely dangerous and lead to several problems, including:



  • Loss of control: A failed CV axle can cause the wheel to separate from the vehicle, leading to a sudden loss of control and increased risk of an accident.

  • Damage to other components: A bad CV axle can cause additional damage to the differential, transmission, or other drivetrain components if driven in that condition.

  • Safety hazards: A broken CV axle can cause the vehicle to become unstable, increasing the risk of a rollover or other serious accident.


For these reasons, it's crucial to address any issues with your CV axle as soon as possible and avoid driving the vehicle until the necessary repairs have been made.

How urgent is a CV axle replacement?


Driving a vehicle with a bad CV Joint is extremely dangerous and could prove costly in the long run by causing further damage to related parts. When you have a failing or bad axle shaft, you have a chance of having it completely fail while you are driving your vehicle.



Can a CV axle break transmission?


Yes, a bad CV joint can cause transmission problems, particularly if the issue leads to increased vibrations, misalignment, or unbalanced power delivery. It's important to address CV joint issues early to prevent damage to the transmission. For a thorough inspection, consider scheduling a Free Diagnostic Check.



What happens if you don't replace a bad CV axle?


The Constant Velocity is sealed by a boot. This boot may get damaged, and when this happens, the joint will wear out and eventually fail. If you drive a car with a damaged CV, the joint will disintegrate further, making driving impossible. You'll not be able to control the vehicle and may get involved in an accident.



Can a bad CV axle damage your transmission?


Ignoring a bad CV axle can lead to more severe issues, including: Damage to Other Components: A damaged CV axle can cause excessive wear on other drivetrain components, such as the transmission and wheel bearings, leading to costly repairs.



How long does it take a mechanic to replace a CV axle?


1.5-3 hours
Labor rates vary from shop to shop but normally it will take 1.5-3 hours to replace a CV axle depending on the make and model of the vehicle. The total labor cost will depend on how many axles you are getting replaced.



How much does it cost to replace a CV axle?


On average, a single axle replacement costs between $300 and $1,500, depending on the type of vehicle and labor hours. The cost of parts ranges between $760 and $1,030, while labor cost is between $170.00 and $180.



What happens when a CV axle fails while driving?


What happens if a CV joint fails? A CV joint failure can cause instability in the vehicle, resulting in strong vibrations in both the steering wheel and engine. Damage to the other components of your car can occur if the issue persists for too long, as contaminants will accumulate in the unprotected weakened joint.



How long can you drive on a bad CV axle?


You may be able to drive a few thousand miles with a bad CV axle, once it starts leaking lubricant, before it gets noisy. Once you can hear it clicking and feel it clunking you it will fail anytime within a few more minutes to maybe another thousand miles or so.



Will a bad CV axle stop a car from moving?


In severe cases, a broken CV axle can cause the vehicle to lose control or stop moving entirely, which can be dangerous, especially at high speeds. Addressing the symptoms early with a CV axle replacement or repair can prevent larger, more costly issues from occurring.



Is a CV axle expensive to fix?


On average, a single axle replacement costs between $300 and $1,500, depending on the type of vehicle and labor hours. The cost of parts ranges between $760 and $1,030, while labor cost is between $170.00 and $180.
