Detailed Description

This Dorman drive shaft assembly, part number 986-573, is built as a complete replacement for rear driveline service where the original shaft is worn, damaged, or out of balance. The steel shaft uses a 60-inch compressed length, 3-inch diameter, and 0.083-inch wall thickness, with a slip yoke at one end and a universal joint at the other. It is supplied as a standard replacement assembly with no adjustable overall length, making it a straightforward option for vehicles that match the listed fitment.

Inspect related driveline components, mounting points, and driveline angles during replacement to help ensure proper fitment and smooth operation.
