Overview
It is a crossover U-joint that converts a Detroit 7260 series joint to a 1310 series joint. It is non-greasable, with inside and outside snap rings, and it is positioned at the front driveshaft at the front axle. It is a direct fit.
The joint is interchangeable with existing parts, so it can be fitted without a change in part number. It uses a computer-designed bearing plate and a manufacturing process that holds close tolerances.
The joint has a bearing cap diameter of 1.078 inches on the inside and 1.062 inches on the outside. The outside snap ring to snap ring measurement is 3.219 inches, and the inside snap ring to snap ring measurement is 2.125 inches. Check those dimensions against the joint you are replacing before ordering.

Choosing and inspecting a U-joint
A U-joint lets the driveshaft carry power through an angle, and a crossover joint is used where the yoke and cross size differ between the driveshaft and the axle. Because this joint is non-greasable, its service life depends on keeping water and grit out of the bearing caps and on checking the joint at each inspection. Matching the joint to the driveline angle matters as much as matching the size.
Driveshaft joints often wear together, so inspecting the other joints in the driveline when one is replaced is a good habit. Worn snap rings, loose bearing caps or a clunk when shifting between drive and coast are signs to look for. Any vibration at highway speed that appears after a joint change should be checked before continuing, since it can point to driveline angles or balance.
- Check the driveline angles when the front axle is lifted
- Inspect the other U-joints during the same job
- Replace the snap rings with the joint when they are worn
