U-joints, or universal joints, are found along the driveshaft or driveshafts of a vehicle, at any point where the driveshaft has to change angle or attach to another component such as a differential. This type of coupling is capable of withstanding large amounts of torque. Proper lubrication ensures that these parts don’t experience any excess friction and won’t wear out prematurely.
Consult the vehicle’s manual for any manufacturer suggestions as to how often the U-joints along the drivetrain need to be inspected. Each time they are inspected, they should be lubricated. While the mechanic is underneath the vehicle, they should also inspect the driveshaft and other parts of the drivetrains to make sure that any symptoms of a U-joint issue weren’t actually caused by something else. For example, vibrations could be caused by an unbalanced wheel or damaged tire.
This service is extremely important if the vehicle is showing any signs that the driveshaft or U-joint is not functioning properly. These parts are under a massive amount of torque and the failure of a spinning shaft is very unpredictable.
