3303-321 – Transmission Yokes – 1330 Series – 31/32 X 1.378 Splines – 1.886″ Hub Dia

3303-321 is a critical Transmission Yoke designed for 1330 Series applications. If you’re experiencing vibrations or driveline slippage, this yoke could be the solution. A worn or damaged yoke can lead to misalignment, causing excessive wear on U-joints and other driveline components. Symptoms like clunking noises during acceleration or deceleration often indicate a failing yoke.

This yoke connects directly to the transmission, providing a secure interface that allows for smooth power transfer. With a spline count of 31/32 X 1.378 and a hub diameter of 1.886 inches, it’s engineered to fit a variety of setups, including popular transmissions like the Turbo 400 (TH400) and Muncie models.

When installing the 3303-321, pay close attention to the following:

• Ensure proper spline engagement depth to avoid premature wear.
• Check for correct phasing with the opposite yoke to maintain driveline balance.
• Inspect the U-joint for compatibility; this yoke fits U-joints with a cap diameter of 1.062 inches.

Replacing a worn yoke with the 3303-321 restores driveline integrity and performance. Don’t overlook this component; it plays a vital role in your vehicle’s overall functionality.
