How do I know my u-joint size?

Table of Contents

You measure from the outer side of the lock ring groove side to side. This gives you the width of the joint lock. You still need to measure the overall width of the joint to make sure it is compatible with the bolt-on yoke.

What is a trunnion u-joint?

A non-constant velocity universal joint consisting of two yokes connected by a cross through four bearings and driveable by external sources. Drive member with four equally spaced trunnions in the same plane and four bearing cups with attaching parts. Also referred to as a universal joint kit or u-joint kit.

How many U-joints does a Silverado have?

you will find three U-joints on a Chevy Silverado. The rear U-joint is in the rear end of the vehicle. The front U-joint is in the front of the vehicle, and the axle is in the middle. The middle U-joint is where the front left tire and the front right tire are attached to the axle.

What is the difference between a 1310 and 1350 U joint?

Size and strength. The 1310 series joint is what you would expect to find stock in most Jeep or small trucks. A 1350 series joint/shaft is what you might find in many full size trucks. While it’s not 100% accurate, you could say that a 1310 is a “half ton” joint and a 1350 is a “one ton joint”.

What is the difference between a 1350 and 1410 U joint?

1350 joints are found in 1-ton trucks and use the wider body of the 1330 joint but with larger trunnions and caps. 1410 joints use a wider body but the same-size caps as a 1350 joint, making them perfect for high-horsepower, high-angle applications.

What are the different types of U-joints?

There are two types of universal joints, defined by their number of bending joints:

Single joint: has only one bending aspect and is capable of operating at up to a 45-degree angle.
Double joint: utilizes two bending joints, the double u-joint can operate at angles up to 90 degrees.

Are U-joints and ball joints the same?

It depends exactly what you want. Ball joints and universal joints aren’t directly comparable as universal joints can transmit torque (as in drive shafts) whereas ball joints just provide location. There isn’t an inherent difference in friction between the two as this will depend on manufacturing tolerances.
