What is a 3/8″ Drive Universal Joint Socket?
A 3/8″ drive universal joint socket is a specialized tool designed to fit and work with universal joints, also known as U-joints. These sockets are typically used in automotive applications to install or remove U-joints from driveshafts, propeller shafts, and other rotating components. Key features of a 3/8″ drive universal joint socket include its compact size, robust construction, and compatibility with various U-joint types. Common applications include routine maintenance, repairs, and replacements in cars, trucks, and other vehicles.

Types of 3/8″ Drive Universal Joint Sockets
Spline Drive Sockets
Spline drive sockets are designed to fit U-joints with splined ends. They offer a secure and precise fit, reducing the risk of slippage during use. Common sizes include 13/16″ and 1-1/8″ splines, and they are compatible with a wide range of U-joints. The splined design ensures that the socket remains firmly in place, even under heavy torque.
Ball Drive Sockets
Ball drive sockets are designed for U-joints with ball-and-socket designs. These sockets typically have a cup-shaped interior that fits over the ball portion of the U-joint, providing a snug and secure fit. Common sizes include 1″ and 1-1/4″ ball drives, making them suitable for various U-joint types. The ball drive design allows for smooth and efficient installation and removal.
Hex Drive Sockets
Hex drive sockets are designed to fit U-joints with hex-shaped ends. They are commonly used in applications where a more straightforward and robust fit is required. Common sizes include 7/8″ and 1″ hex drives, and they are compatible with a wide range of U-joints. The hex drive design ensures that the socket can apply maximum torque without slipping.
