Too Afraid to Ask

U joints are parts that help connect different parts of a car's drivetrain. They allow those parts to move freely even when they are not perfectly aligned.

Technical Definition

U joints, or universal joints, are mechanical components that allow for the transmission of torque and rotation between two shafts that are not in a straight line. They are commonly found in drive shafts of vehicles, enabling flexibility in movement.
