U-Joint Inspection and Replacement

A U-joint, short for universal joint, is a mechanical device used to connect two rotating shafts at an angle to each other. It is commonly used in automotive and industrial applications, such as driveshafts, steering systems, and machine linkages.

A U-joint consists of two yokes, each with a set of bearings and a cross-shaped component that connects them. The yokes are typically positioned at a 90-degree angle to each other, allowing the U-joint to transmit torque and rotational movement between two shafts that are not in a straight line.

U-joints are designed to compensate for minor misalignments between the shafts they connect, allowing for smooth and efficient power transfer. They are also flexible and can handle a range of angles and movements, making them ideal for use in a variety of applications. However, if a U-joint is worn or damaged, it can cause vibrations, noise, or even complete failure of the connected components. Regular inspection and maintenance of U-joints is important to ensure proper operation and prevent costly repairs.

The driveshaft and universal joints should be carefully inspected whenever any of the following symptoms occur:

  • Vibration or harshness at highway speed
  • a clicking sound whenever the vehicle is moving either forward or reverse
  • A clunking sound whenever changing gears, such as moving from drive to reverse.

The U-Joint can be defective and still not show noticeable free movement. A roper U-Joint inspection can only be performed by removing the driveshaft from the vehicle.

During a professional service the driveshaft is inspected for dents, foreign object debris, and excessive free movement. We will also lubricate any grease fittings.

The driveshaft must travels up and down as the vehicle moves over bumps and dips in the road. While rotating freely it continues transmitting engine power to the drive wheels. Unequal or incorrect U-joint working angles can cause severe vibrations.
