What sound does a damaged CV joint make?

[EvangelineFitz]

The most obvious sign of inner CV joint damage is a "clicking" noise coming from the transmission area when accelerating or driving on uneven roads, accompanied by CV joint grease leakage. In severe cases, abnormal sounds may also occur when turning the car. Below is relevant information about CV joints:1. There are two common types of CV joints in cars: one is the fixed-type ball cage joint (RF joint), which allows only relative rotation between the driving and driven shafts without axial displacement during torque transmission, typically used near the wheels (commonly referred to as the outer CV joint); the other is the sliding-type ball cage joint (VL joint), which not only allows relative rotation but also axial displacement during torque transmission, usually installed near the drive axle (commonly known as the inner CV joint).2. In most cases of CV joint damage, the "clicking" noise occurs mainly during acceleration when the vehicle is under load, rarely during coasting. Intermittent acceleration and deceleration can help detect excessive play in the front axle's CV joints. Excessive CV joint play may cause slight front wheel vibration during startup and noticeable power transfer fluctuations when releasing the throttle.

I last encountered this issue while taking a highway curve when a sudden metallic clicking sound came from under the car, very much like marbles rattling in a tin can. The noise was most noticeable during hard acceleration in turns and diminished when straightening the wheel. It was accompanied by slight vibrations transmitted to the steering wheel. Upon inspection, I found the driveshaft boot torn with all the grease leaked out. This kind of sound can't be ignored - delaying repairs could ruin the entire driveshaft. Ultimately, replacing the CV joint assembly fixed the problem.

My experience with older cars taught me that the first sign of a failing CV joint is abnormal noises when turning. My station wagon always makes a clicking sound when turning right, similar to the crisp sound of hard plastic repeatedly snapping, with the frequency increasing as speed rises. Once, when fully loaded and climbing a slope while turning, it suddenly changed to a metallic screeching sound, which scared me into getting it fixed immediately. The veteran mechanic said that when the inner CV joint wears out, there might be a dull sound even when driving straight, while the outer CV joint mainly makes noise when turning under load. If you wait until you hear a loud bang while driving, it's likely that the ball bearings have seized.

Last week, my neighbor's car made noises when going over speed bumps, so he asked me to test drive it. At low-speed turns, there was a distinct rhythmic clicking sound from the wheel area, like tapping the brake disc with a screwdriver. After lifting it on a hoist, we found the left outer CV joint boot was torn, allowing dirt to enter and wear down the ball track. The mechanic warned that the noise initially resembles a pebble stuck in the tire but can progress to a harsh metal scraping sound, especially becoming more frequent in rainy conditions when water gets in.

During car repairs, I've seen severely worn CV joints where the loose steel balls rattling inside the cage grooves create noise. Typical symptoms progress in three stages: initial phase shows brief clicking sounds when turning; intermediate phase develops continuous tapping noises resembling gear grinding; final stage escalates to metallic clunking sounds. Once, a customer's car suddenly produced firecracker-like popping noises from the chassis during acceleration - when towed in, we found the CV joint had disintegrated and shattered the transmission housing. If you hear abnormal noises daily, it's best not to continue driving to prevent steel balls scattering and damaging other components.

I remember my driving instructor demonstrating the sound of a CV joint failure: he deliberately loosened the CV joint bolts, and during slalom driving, a rhythmic clicking sound emerged in the car, resembling a second hand ticking but duller. Later, my own car made a similar noise when turning left uphill, and inspection revealed the outer CV joint had excessive clearance of 2mm. The repair shop owner said this sound is particularly easy to misdiagnose—some people mistake it for a driveshaft issue and repair it as such. In reality, you just need to listen for the location: CV joint noises always vary with steering angle, while rattling over bumps indicates suspension problems.
