3104-28 – End Yoke – 28 Splines – 1.218″ Splines Dia

The 3104-28 End Yoke is specifically engineered to connect the driveshaft to the transmission or differential in FORD 9 applications. This yoke features 28 splines with a diameter of 1.218″, making it a vital component in the 1310 Series. The series designation is essential as it determines the cap diameter and cross width of the mating U-joint, ensuring proper fitment and torque transfer.

With a hub diameter of 1.812″, the 3104-28 provides a robust interface to handle the torque loads typical in high-performance and heavy-duty applications. The 4.000″ Cj to end length allows for necessary axial movement, accommodating suspension travel without compromising the integrity of the driveline. This axial movement is critical in maintaining alignment and preventing premature wear on the U-joint and yoke.

When installing the 3104-28, it’s important to:

• Verify spline engagement depth to ensure proper fit.
• Check phasing with the opposite yoke to maintain balance.
• Never force spline entry to avoid damaging the splines.

Additionally, the through hole measures 2.425″, allowing for secure attachment to the companion flange or driveshaft tubing. The style designation UB indicates a specific configuration that aligns with common installation practices in the field. Overall, the 3104-28 End Yoke is a reliable choice for any driveline setup requiring precision and durability.
