Detailed Description

This Dorman drive shaft is built for rear driveline replacement on the BMW 640i and is engineered around the listed OE-style dimensions and mounting style. The assembly uses a bolt-on end on one side and a splined end on the other, with a steel shaft and a 0.083 in wall thickness for a direct-fit service solution. It is also multi-piece and overall length adjustable, with a maximum slip of 1 in to help match the original driveline setup. This part cross-references BMW OE numbers 26107632630 and 26108693401 for the same application.

Installation Notes and Tips

Verify compressed length, flange-to-flange dimensions, and end types before installation. Confirm the rear application on the BMW 640i and inspect mating components, including flange surfaces and adjacent driveline hardware, for wear or damage before mounting the new shaft. Because the assembly is pre-balanced, avoid altering the shaft before installation.
