Detailed Description

This Dorman drive shaft assembly is built for straightforward replacement when the original shaft is worn, damaged, or out of balance. The assembly includes new yokes, tubes, CV joints, and universal joints, and it arrives pre-balanced to reduce setup time during service. The steel construction, 2.5-inch shaft diameter, and 76.25-inch flange face-to-flange face length support a direct-fit driveline repair where the original dimensions match. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number 986-680 is also referenced as PT009547.

What It Helps Fix

• Driveline vibration caused by a worn or unbalanced shaft
• Clunking or driveline noise from worn universal joints
• Binding or rough operation from failed CV joints
• Damage to the original shaft tube or yokes
• Service issues related to incorrect shaft length or phase

Installation Notes and Tips

Verify compressed length, flange-to-flange length, slip yoke style, and bolt-on end configuration before installation. Confirm the shaft is phased correctly and that the vehicle’s driveline measurements match the listed 76.25-inch length and 1-inch maximum slip. Because this assembly is pre-greased and includes new joints, it is ready for installation once the vehicle-specific dimensions and mounting points are confirmed. Fits Chevrolet Silverado and GMC Sierra applications only when the original driveline specifications match this configuration.
