How To Identify U Joints
What U Joint Series Do I Have?
Universal joints, also called U joints, are a very vital part in the operation of your drive shaft and having the right series of U joint is crucial. There are many different series of u-joints. We carry a wide selection of U-joints for many different series. In the event that there is a u joint that we do not stock in our inventory, we can easily order the part for you, along with other parts.
When identifying U-joints, the first thing to identify is whether the U-joint has inside or outside snap rings.
After identifying the configuration of the snap rings, then it’s time to find the dimensions of your U-joint. You will need to find the diameter of one of your u-joint’s caps. This needs to be done for u-joints with inside or outside snap rings. The other dimension that you need to find varies between the two types of u-joint configurations.
For u-joints with inside snap rings, you will see a groove on all of the u-joint caps. You will need to measure from the edge of one snap ring groove straight across to the edge of the other snap ring groove. For U-joints with outside snap rings, you will need to measure from the edge of one u-joint cap straight across to the edge of the other u-joint cap.
With these dimensions, it will be easy to identify what series of U-joint that you have. Another way to identify a u-joint is by properly measuring the pinion yoke.
Each diagram below will show you which measurements to take in order to identify your u joint.
