How to measure a yoke & u-jointFind the correct u-joint quicklyWhen all you have from a vehicle is a yolk or a u-joint use the SKF yoke / u-joint ruler to determine the correct driveshaft series you are working with. Once you determine the correct series refer to the current SKF u-joint catalog to find the correct UJ part number for the application.

How to measure a yoke and u-jointThis simple tool will allow you to locate the correct u-joint for the vehicle. Cut out the rulers and follow these steps to help determine the correct parts for your application.

Wing-style yokesStep 1. Measure across the inside

of the pilot diameter making sure the ruler is over the center of each opposing

bolt hole.Step 2. Result is shown on right

hand side of ruler – 7C in this example

Step 3. Refer to the SKF u-joint catalog pages in order to cross reference the appropriate UJ series part number for the vehicle.

Half-round pinion yokeStep 1. Measure inside the yoke

across the flangesStep 2. The corresponding

driveshaft/u-joint series will be located on the ruler – 1350 in this example

Step 3. Refer to the SKF u-joint catalog pages in order to cross reference the appropriate UJ series part number for the vehicle.

Measuring a u-jointStep 1. Measure across cap to cap

as shown.Step 2. The u-joint series will be

shown on the right hand side of the ruler – 1350 in this example

Step 3. Refer to the SKF u-joint catalog pages in order to cross reference the appropriate UJ series part number for the vehicle.

Full-round driveshaft yokeStep 1. Measure from the outside

of the yoke ears. (In this example we use a flange yoke)

Step 2. The corresponding driveshaft/u-joint series will be located on the opposite ear – 1350 in this example.

Step 3. Refer to the SKF u-joint catalog pages in order to cross reference the appropriate UJ series part number for the vehicle.
