170-82-21X – Yoke Shafts – SPL170 Series – 3.858″ Splines dia – 38 Spline

The 170-82-21X Yoke Shaft is a crucial component for maintaining driveline integrity, particularly in SPL170 Series applications. If you’re experiencing vibrations or unusual noises during acceleration, it’s worth checking the yoke shaft. A worn or damaged yoke can lead to misalignment, resulting in excessive wear on the U-joint and other driveline components.

This yoke shaft features a spline diameter of 3.858 inches and a count of 38 splines, ensuring a secure fit and reliable performance. The spline length measures 9.193 inches, providing adequate engagement for smooth operation. Additionally, the centerline to end measurement of 11.811 inches is critical for maintaining proper driveline geometry.

• Check spline engagement depth to ensure proper fit.
• Verify phasing with the opposite yoke to prevent vibrations.
• Inspect for signs of wear, such as scoring or pitting on the splines.
• Use Boot Cap Part 109-30-2-94M for optimal sealing.
• Ensure correct alignment during installation to avoid premature failure.

In summary, the 170-82-21X is not just another yoke shaft; it’s a vital part of your driveline system. By replacing a worn or damaged yoke shaft with this specific model, you restore the driveline’s functionality and prevent further damage to associated components. Trust the specifications of the 170-82-21X to deliver the performance you need.
