What are the symptoms of a damaged outer CV joint?
2 Answers
Here are the symptoms of a damaged outer CV joint in a car: 1. During vehicle startup and driving, there will be rhythmic abnormal noises from the CV joint, accompanied by steering deviation. In severe cases, wheel power transmission may be interrupted, especially noticeable during turning acceleration, affecting normal vehicle operation. If the CV joint is not replaced promptly, it may cause damage to other front axle components such as steering ball joints, tie rod rubber bushings, and even the entire suspension system. Most CV joint failures occur due to damage to the rubber sealing boot, which leads to lubricant leakage and causes abnormal wear on the outer CV joint. 2. The most obvious characteristic of outer CV joint damage is that the car operates normally during straight-line driving, but produces clicking noises from the front wheel area during turns. In severe cases, steering may become impossible.
When the outer CV joint fails, there are quite a few symptoms. The one I'm most familiar with is the metallic clunking sound when turning, especially during low-speed steering or cornering, as if the tires are gnawing on something—it's particularly grating. This condition is often caused by wear or grease leakage, where the grease drips onto the ground, leaving an oily residue. Over time, the vibration intensifies, making the car feel unstable in direction, with slight steering wheel tremors. In severe cases, the wheel's balance is disrupted, leading to accelerated tire wear or even sudden drivetrain disengagement while driving, which can be dangerous. I remember seeing a car once that wasn't repaired in time—it wobbled like it was dancing while driving. So, once you hear unusual noises or spot grease leakage, get it checked immediately. Repairs aren't expensive; just replacing the CV joint will do the trick, preventing bigger issues. Regular maintenance of the driveshaft can extend its lifespan.
