How To Measure for a Driveshaft

Vehicles can contain one or multiple driveshafts to allow mobility, depending on the size of the vehicle itself. The driveshaft is responsible for transferring torque and engine rotation into vehicle motion during the shifting process. Without this vital component, you cannot drive the vehicle. When working on your car or truck, be sure you know how to measure for a driveshaft to install this essential part successfully.

Driveshaft Configuration

To properly measure your auto driveshaft, you will need to know the configuration. Each type of vehicle uses a driveshaft differently. There are four main configurations. Determining the one you'll need will depend on whether the vehicle features front-wheel, four-wheel, front-engine, or rear-wheel drive.

Understanding Parts

If your vehicle has front-engine or rear-wheel drive, the driveshaft will have to be longer to connect the rear axle to the transmission. The driveshaft connects these components as they are in different locations, often at opposite ends of the vehicle. Motorcycles, trains, and even boats use driveshafts to transfer power between parts.

Properly Measuring

These are the four most common types of configurations for driveshafts:

Flange to the End Yoke: You will measure from the U-joint to the flange face from the center of the joint.

Flange to Flange: You will measure the face of one flange to the face of the other.

End Yoke to the Spline: You will measure from the center of the U-joint to the spline's tip.

End Yoke to End Yoke: You will measure from the center of one of the U-joints to the center of the other U-joint.

You should familiarize yourself with the terminology of the driveshaft and its surrounding components.
