1503-22 – Transmission Yokes – 1551 Series – 20/22 X 0.959 Splines – 1.375″ Hub Dia

1503-22 is a critical component in the driveline of Mazda vehicles, specifically designed as a Transmission Yoke. This yoke features a spline count of 20/22 X 0.959, ensuring a precise fit for optimal torque transfer. If you notice vibrations or clunking noises during acceleration, it may indicate that the yoke is worn or improperly engaged. A worn yoke can lead to misalignment, which exacerbates wear on the U-joint and other driveline components.

With a hub diameter of 1.375 inches and a center U-joint to end measurement of 5.710 inches, the 1503-22 yoke provides the necessary dimensions for effective engagement with the transmission. The counter bore diameter of 625 inches allows for a snug fit, reducing the chance of play that can lead to premature failure. If you experience difficulty during installation, it’s crucial to check the spline engagement depth and ensure proper phasing with the opposite yoke.

Here are some key points to remember when working with the 1503-22 Transmission Yoke:

• Spline count: 20/22 X 0.959
• Hub diameter: 1.375 inches
• Center U-joint to end: 5.710 inches
• Counter bore diameter: 625 inches
• Designed for Mazda OE applications

Replacing a failed yoke with the 1503-22 restores proper function and enhances the reliability of your driveline system. Don’t overlook the importance of this component in maintaining the overall health of your vehicle.
