Question

Quizplus · Accepted Answer

Driveshaft U-joints are not necessarily engineered to last the life of the vehicle and can wear out or fail, requiring replacement. Replacing driveline propeller shaft assemblies is not always a common shop practice, as individual components like U-joints can often be replaced without needing to replace the entire assembly.
