A center bearing assembly is a crucial component in vehicles with a two-piece driveshaft, commonly found in rear-wheel and four-wheel drive systems. It supports the middle of the driveshaft, keeping it properly aligned and allowing it to rotate smoothly at high speeds. The assembly includes a bearing mounted in a rubber cushion, which helps absorb vibrations and reduce noise. When the center bearing wears out or fails, drivers may notice vibrations during acceleration, clunking noises or drivetrain misalignment. Replacing a faulty center bearing ensures smooth power delivery, reduces wear on other drivetrain parts and restores driving comfort.
