General Information:

The Constant Velocity (CV) axle is a key component of your vehicle’s drivetrain, responsible for transferring power from the transmission to the wheels. It allows for smooth rotation of the wheels, even as they turn or when the suspension moves up and down. Over time, the CV axle can wear out, especially if the protective CV boot is damaged, leading to grease leakage and potential axle failure.

How to Detect the Problem:

- Clicking Noise When Turning: One of the most common signs of a failing CV axle is a clicking or popping noise when making sharp turns.

- Vibrations While Driving: A worn-out CV axle can cause excessive vibrations that increase with speed.

- Grease on the Inside of Your Tires: A torn CV boot will leak grease, which may splatter onto the inside of the wheel and surrounding area.

- Difficulty Steering: A damaged CV axle can affect the handling and steering of your vehicle, making it difficult to control.

How the Problem is Fixed:

- CV Boot Replacement: If the CV boot is the only component damaged, replacing it might prevent further damage to the axle.

- CV Axle Replacement: If the axle itself is worn out or damaged, it will need to be replaced with a new one.

- Lubrication and Inspection: The new axle is properly lubricated and the surrounding components are inspected to ensure they are in good condition.

How Long It Takes to Fix:

- Inspection: 30 minutes to 1 hour.

- Replacement: 1 to 3 hours, depending on the make and model of the vehicle and whether one or both axles need replacement.

How Often It Should Be Checked:

- Routine Maintenance: CV axles should be inspected during regular maintenance visits, especially if the vehicle has high mileage or is used in rough driving conditions.

- At Signs of Trouble: Immediately if you notice any clicking noises, vibrations, or grease leakage, as these symptoms indicate potential CV axle issues.
