CV Joint Symptoms: A Comprehensive Guide

Learn the symptoms of a failing CV joint

CV joints usually fail after the rubber boot is damaged. The boot allows the CV joint to flex in turns while still retaining all the lubricating grease. However, once the boot wears and leaks or is torn, the spinning axle shaft flings all the grease out of the joint, and road grit can enter. Between the lack of lubrication and the influx of grit, the joint doesn’t stand a chance. It wears out quickly and fails. Here are the most common CV joint symptoms

1) A torn CV boot will fling grease onto the tire and in a circular pattern around the joint. That’s the first sign of CV joint failure

Once the joint loses grease, it will start to wear. As road grit enters the joint, the wear will accelerate

2) A failing CV joint makes a clicking oro popping sound in sharp turns at low speeds

Without any grease, the ball bearing and lands wear. When you’re in a sharp turn the worn parts will make a repeating clicking sound. Once a joint starts clicking, the wear will accelerate rapidly

3) A bad CV joint can cause a knocking/clunking noise

You hear a knock or clunk sound when you shift into drive and the transmission transfer torque to the drive shaft. Then you’ll hear a knocking sound as you take off from a stop or it may be worse in reverse. The sound will be rhythmic since the play in the joint will repeat with each revolution.

4) CV joint vibration at higher speeds

A worn CV joint can cause vibration at a higher speed because the joint is out-of-balance due to wear. The vibration can feel like a tire imbalance or even a bad tire. But the one different thing is that the vibration will change when you accelerate or decelerate as the torque changes affect the worn parts differently.

It’s important to note that some of these symptoms, such as clicking noises or vibrations, may also be indicative of other issues, such as worn suspension components or wheel bearings. Therefore, it’s crucial to have a professional mechanic inspect your vehicle and properly diagnose the root cause of the problem.

Neglecting a failing CV joint can lead to more severe consequences, including complete joint failure, which can result in loss of control or even a breakdown. By staying aware of the symptoms and addressing any issues promptly, you can help ensure the safety and longevity of your vehicle.
