Under normal circumstances, u-joints last a long time. Some even last the lifetime of the vehicle. But sometimes a U-joint can fail unexpectedly. When that happens, you have to replace it ASAP. Neglecting to replace a failed u-joint will likely result in serious issues such as:
· Driveshaft damage
· Transmission failure
· Differential damage or failure
· Unsafe driving conditions
When one of your u-joints fails, you'll notice. You will notice some symptoms. It's important to know what to look for so you can address a failed u-joint before the damage becomes irreparable.
1. Replace Your U-Joints When You Hear A Clunking Sound
When a u-joint fails, it produces noises. The noise can be steady or intermittent. Even if the radio is turned down, it is generally loud enough to hear.
A clunking sound is a common indication that a u-joint is about to fail. This occurs when transitioning from forward to reverse or backward to forward. This indicates that at least one u-joint is starting to fail. The good news is that replacing the u-joint soon usually results in no more damage.
2. Replace Your U-Joints When You Feel Drivetrain Vibration
The most prevalent cause of excessive drivetrain vibration is u-joint failure. When a u-joint fails, the driveshaft may start to move outside of its regular rotation. In other words, it becomes excessively loose. This creates drivetrain vibration, which is most evident at high speeds. You can sometimes feel the tremor through the floorboards and shift lever.
What Happens When You Don't Replace Your U-Joints
Ignoring these symptoms can result in a u-joint that self-destructs. The driveshaft is then free to bang on the bottom of the vehicle, leading to even more damage. You'll face some dire consequences if you don't replace your u-joints ASAP. Most commonly:
· Significant driveshaft damage
· Transmission failure due to a damaged output shaft seal
· Differential failure due to a damaged pinion seal
