The U-joint is a critical component in a vehicle’s drivetrain, allowing the driveshaft to transmit power at varying angles between the transmission and the differential. Over time, these joints can wear out due to constant motion, lack of lubrication, or heavy loads, leading to symptoms like vibrations, clunking noises, or even complete failure. The replacement restores the driveshaft’s ability to transfer power efficiently and quietly, eliminating vibrations and preventing further damage to oth
