Product Details

Dorman 986-458 is a standard replacement drive shaft assembly engineered for rear-position service on 2021-2026 Cadillac Escalade ESV and 2021-2026 GMC Yukon XL applications. The aluminum shaft measures 80.125 inches in compressed length, with a 4-inch shaft diameter and 0.083-inch wall thickness. It uses a slip yoke at end 1 and a bolt-on connection at end 2, and it is supplied without a slip yoke, axle nut, or CV joints. This part cross-references Monroe Shocks & Struts (e.g., 84712238, 84816761) for the same application.

Common Issues This Part Can Address

• Vibration from a worn or out-of-balance rear driveshaft
• Clunking or driveline noise from worn universal joints
• Driveline play caused by damaged yokes or shaft tubing
• Loss of smooth power transfer to the rear axle
• Service replacement for a bent or fatigued drive shaft assembly

Installation Notes and Tips

Verify rear-position fitment by year, make, and model before installation. Confirm the slip yoke and bolt-on end configuration matches the original driveline setup, and compare the compressed length, shaft diameter, and wall thickness to the removed part. Because this assembly is pre-balanced, handle it carefully during installation to avoid affecting balance.

Quality Assurance

Dorman supplies this drive shaft as a complete standard replacement assembly with new yokes, tubes, and universal joints. The part is built for direct replacement service on the listed Cadillac Escalade ESV and GMC Yukon XL rear applications.
