Detailed Description

Dorman 986-581 is engineered as a direct-fit rear drive shaft for Audi A4 allroad and Audi A4 Quattro models equipped with PR Code GH1 basic rear differential. The assembly uses steel tubing and bolt-on ends, with a fixed 65.75-inch compressed length and 0.083-inch wall thickness. Because the shaft is supplied as a complete assembly, it supports a straightforward driveline replacement when the original shaft is worn, damaged, or out of balance.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What This Drive Shaft Helps Address

• Driveline vibration from a worn or unbalanced shaft
• Noise from damaged joints or worn shaft components
• Loss of driveline smoothness under load
• Replacement needs after shaft tube or yoke wear
• Rear driveline service on Audi A4 allroad and Audi A4 Quattro models

Installation Notes and Tips

Verify PR Code GH1 before ordering. Confirm rear-position fitment, bolt-on end configuration, and overall length against the original shaft before installation. Inspect mating flanges, fasteners, and surrounding driveline components for wear or damage during replacement. Professional installation is recommended for driveline alignment and proper torque procedures.

Quality Assurance

Dorman supplies this drive shaft as a standard replacement assembly with new internal and external wear components. The pre-balanced design supports installation on the specified Audi A4 allroad and Audi A4 Quattro rear applications.
