Detailed Description
The Dorman 986-497 drive shaft is built for rear fitment on the Mercedes-Benz 300SD from 1981 through 1985. It is a complete assembly with new yokes, tubes, and universal joints, and it is pre-balanced to reduce the need for additional driveline preparation before installation.

What It Helps Address

- Loss of smooth power transfer to the rear axle
- Replacement needs after shaft damage or corrosion
Installation Notes and Tips
Verify rear application, compressed length, shaft diameter, and bolt-on end configuration before installation on the Mercedes-Benz 300SD. Inspect mating flanges, driveline angles, and surrounding components for wear before mounting the new shaft. Because this assembly is pre-balanced, avoid altering the shaft or adding modifications that could affect balance after installation.
Quality Assurance
