Detailed Description

This Dorman drive shaft is built as a complete replacement assembly for rear driveline service where the original shaft is worn, damaged, or out of balance. The steel shaft uses a 3.5-inch diameter and 0.083-inch wall thickness, with an adjustable overall length to help match the vehicle’s driveline requirements. The included slip yoke supports proper engagement at the transmission or transfer case, and the assembly is supplied ready for installation without reused yokes or tubes. For buyers searching for a Ford F-250 drive shaft replacement or Ford F-350 drive shaft replacement, Dorman 986-005 provides a direct-service solution for common heavy-duty driveline repairs.

This part cross-references Ford OE 8C3Z4R602Y for the same application.

What It Helps Fix

• Vibration caused by a worn or out-of-balance driveshaft
• Clunking or driveline noise from damaged joints or yokes
• Excessive play from a worn slip yoke connection
• Driveline failure from cracked or bent shaft tubing
• Service issues on Ford F-250 and Ford F-350 driveline assemblies

Installation Notes and Tips

Verify shaft length, slip yoke engagement, and driveline configuration before installation. Because this assembly is pre-balanced, avoid adding weight or modifying the shaft during service. Inspect companion flange, transfer case output, and differential mounting points for wear before installing the replacement shaft. Confirm application details against the vehicle’s original driveline specifications for Ford F-250 and Ford F-350 service.

Quality Assurance

Dorman supplies this drive shaft as a new replacement assembly with new yokes, tubes, CV joints, and universal joints. The pre-balanced design supports consistent driveline operation after installation, and the steel construction is intended for regular-duty service.
