Measuring the Universal Joint

1. Take apart the universal joint

Disassemble the universal joint for measuring properly. Click the link below for a handy reference for replacing your U joint. PDF document from Weasler®.

2. Measure the U Joint

When you measure your universal joint, measure the length from one outer end to the other (D). You will also need to record the width of one end of the universal joint (C). Use these numbers to find the right size of a universal joint.

On the Domestic type like this one, the snap ring can be of type A or B.
