5504-01 – End Yoke – 1550 Series – 1.609″ Splines Dia – 2.500″ Hub Dia

The 5504-01 End Yoke is essential for connecting the driveshaft to the transmission, transfer case, or differential in DANA 80 applications. With 37 splines measuring 1.609″ in diameter and a hub diameter of 2.500″, this yoke is part of the 1550 Series. The specific spline count and dimensions are crucial for ensuring compatibility with the correct U-joint, which is vital for maintaining driveline integrity.

Using a yoke that doesn’t match these specifications can lead to improper fitment, resulting in excessive wear or even catastrophic failure. For instance, a yoke with a different spline count or diameter may not properly engage the U-joint, leading to vibrations or driveline noise. This can compromise the entire driveline system, making it essential to select the right part.

When installing the 5504-01, keep these key points in mind:

• Check spline engagement depth to ensure proper fit.
• Verify phasing with the opposite yoke to prevent driveline vibrations.
• Never force spline entry; align carefully to avoid damage.
• Inspect the mating components as a system for optimal performance.

In summary, the 5504-01 End Yoke is a reliable choice for those working on DANA 80 applications, ensuring a secure connection and smooth operation.
