1302-15 – Flange Yokes – 1351-20 Series – Bolt Circle Dia 3.340″ – Pilot Dia 1.811, M

1302-15 is a Flange Yoke that plays a critical role in connecting the driveshaft to the transmission, transfer case, or differential. If you’re experiencing vibrations or unusual noises during acceleration, this yoke might be the culprit. A worn or damaged yoke can lead to misalignment, which often manifests as a clunking sound or excessive play in the driveline. This specific yoke, designed for 1351-20 Series applications, features a bolt circle diameter of 3.340 inches and a pilot diameter of 1.811 inches, ensuring a secure fit and proper alignment.

When diagnosing driveline issues, pay attention to the symptoms. If you notice a vibration that correlates with vehicle speed, it could indicate a failing yoke or U-joint. The 1302-15 yoke’s dimensions are crucial; the bolt hole diameter of 0.410 inches and the Cj to flat measurement of 1.750 inches are designed to match perfectly with compatible components.

• Check spline engagement depth before installation.
• Ensure proper phasing with the opposite yoke to avoid driveline vibrations.
• Verify that the bolt holes (4) align correctly with the companion flange.
• Inspect for wear or damage regularly to maintain driveline integrity.

Using the 1302-15 yoke not only restores functionality but also enhances the overall performance of your driveline system. Don’t overlook this essential component when addressing driveline concerns.
