Detailed Product Overview

Dorman 986-390 is a steel rear drive shaft assembly built for BMW driveline replacement where the original shaft has worn joints, vibration, or balance issues. The assembly measures 57.625 in in compressed length and uses a 0.083 in wall thickness for the specified application. Because the shaft is supplied as a complete unit with new CV and universal joints, it reduces the need to rebuild individual driveline components during service. This part cross-references BMW OE number 26107638486 for the same application.

Compatible With 2012-2015 BMW 335i, rear; 2014-2016 BMW 435i, rear; and 2015-2016 BMW 435i Gran Coupe, rear. Use Dorman 986-390 when replacing a rear driveshaft on these BMW models and when the original shaft shows driveline noise, vibration, or joint wear.

Common Issues This Part Can Address

• Driveline vibration at speed
• Clunking or knocking from worn joints
• Noise from a damaged or out-of-balance shaft
• Wear in the original CV joint or universal joint
• Failure of the factory driveshaft assembly

Installation Notes and Tips

Verify rear application, compressed length, end configuration, and shaft diameter before installation. Inspect mating driveline components, mounting points, and seals for wear before fitting the replacement shaft. Because this assembly is not adjustable and does not include a slip yoke, confirm the vehicle configuration matches the listed BMW 335i, 435i, or 435i Gran Coupe rear application before service.

Quality Assurance

Dorman supplies this driveshaft as a complete replacement assembly with new internal wear components and pre-balanced construction for the listed BMW applications. Part number 986-390 is built to match the specified rear driveline fitment for 2012-2016 BMW 335i, 2014-2016 BMW 435i, and 2015-2016 BMW 435i Gran Coupe models.
