When you think about the parts that keep your car moving, you probably picture the engine and the transmission. But one of the most essential components in transferring power to your wheels, especially in front-wheel-drive and many all-wheel-drive vehicles, is the CV joint. Short for a “constant velocity” joint, this critical part ensures your wheels get consistent power while allowing for smooth movement as the suspension travels and the wheels turn.
Unfortunately, CV joints don’t last forever. When they begin to fail, they can cause serious drivability issues and lead to further damage if ignored.
What Does a CV Joint Do In Your Vehicle
The CV joint sits at each end of the axle shaft, connecting it to the wheel and transmission. Its job is to maintain even torque while the suspension moves and the wheels turn. Without it, your car wouldn’t be able to maintain power to the wheels during cornering or while going over bumps.
To protect the joint and keep it lubricated, a rubber boot, known as a CV boot, covers it and holds it in grease. When this boot cracks or tears, dirt and moisture can enter, causing the joint to wear down quickly.
Common Symptoms of CV Joint Trouble
Most drivers won’t notice CV joint wear right away, but once the symptoms appear, they’re hard to ignore. One of the most telltale signs is a clicking or popping noise when turning, especially if the sound gets louder the more sharply you steer. This noise typically means the outer CV joint is worn and struggling to keep up with the movement of the wheels.
Another symptom is noticeable vibration while driving. If the inner CV joint is worn, you can feel a rhythmic shake, often tied to acceleration. It can feel similar to unbalanced tires or a warped brake rotor, but if the vibration worsens with throttle input, the CV joint may be to blame.
In more advanced cases, you may hear knocking sounds, especially when shifting between drive and reverse. You might also see grease splattered inside the wheel well, which is a strong indicator that the CV boot has failed and the joint is exposed.
What Happens If You Ignore CV Joint Issues
A failing CV joint doesn’t heal on its own. Once the protective boot is damaged, the joint wears out quickly. If left untreated, it can eventually break apart entirely, resulting in a complete loss of power to the wheel. This usually happens during a turn or while accelerating, and it can leave your car stranded on the spot.
Worse yet, a damaged CV joint can affect other components in the drivetrain or suspension if it fails while the car is in motion. That’s why it's crucial to take early signs seriously and have your vehicle checked promptly.
How Long Should CV Joints Last
Under normal conditions, CV joints can last well over 100,000 miles. But their longevity depends heavily on the condition of the CV boots. If the boots stay intact and the grease remains sealed, the joint may last the life of the vehicle. However, exposure to road salt, potholes, and extreme driving conditions can cause them to wear down more quickly.
If you're driving a higher-mileage vehicle or frequently hear clicking sounds on turns, it’s wise to have the CV joints inspected, even if no obvious damage is visible yet.
Diagnosis and Repair Options
Fortunately, a worn CV joint isn’t the end of the world. If caught early, your technician may only need to replace the damaged boot and repack the grease. If the joint itself is already worn, a new axle shaft (which includes the CV joints) is typically the most efficient and cost-effective fix.
It’s also a good idea to inspect both sides of the vehicle when one CV joint is found to be damaged. If one has failed due to age or mileage, the other may not be far behind.
