Detailed Description

This Dorman drive shaft is built as a direct replacement for rear applications on 2018-2022 Subaru Crosstrek and 2019-2022 Subaru Forester. The assembly measures 63 inches in drive shaft length and uses a steel tube with 0.065 in. wall thickness for a service-ready replacement. It is pre-greased, includes universal joints, and arrives pre-balanced to reduce the setup work normally associated with driveline repair. This part number 986-691 is also referenced by interchange number 27111FL120.

What It Helps Fix

• Vibration from a worn or out-of-balance rear driveshaft
• Clunking or driveline noise from worn universal joints
• Binding or rough rotation caused by damaged CV joints
• Driveline play related to worn yokes or tube damage
• Loss of smooth power transfer to the rear axle

Installation Notes and Tips

Verify rear fitment by model year before installation. Confirm the slip yoke and bolt-on end configuration matches the vehicle, and inspect related driveline components for wear before mounting the new assembly. Because this shaft is phased at 90 degrees and pre-balanced, install it in the correct orientation and torque all fasteners to the vehicle manufacturer’s specifications.

Quality Assurance

Dorman supplies this as a standard replacement driveline assembly with new major wear components already installed. The pre-balanced design and new yokes, tubes, CV joints, and universal joints support consistent fit and function for rear driveline service on Subaru Crosstrek and Subaru Forester applications.
