SKF BR931103 Wheel Bearing and Hub Assembly - Rear

SKF Rear Wheel Bearing Hub Assembly BR931103

SKF BR931103 is a rear wheel bearing and hub assembly built for Subaru applications that need precise wheel-end support, stable braking feel, and consistent hub stiffness. It is engineered with SKF wheel-end technology and uses a double row angular contact ball bearing design for demanding driving conditions.

Compatible with 2015-2021 Subaru Legacy rear, 2015-2021 Subaru Outback rear, and 2019-2021 Subaru Ascent rear, this SKF wheel bearing kit is a direct-fit service part for rear hub replacement. The BR931103 also cross-references Subaru 28473AL00A for the same application.

Key Features

• Rear wheel bearing and hub assembly for Subaru Legacy, Outback, and Ascent
• SKF BR931103 part number for catalog and service matching
• Double row angular contact ball bearing arrangement
• Increased bearing capacity with improved hub stiffness
• Encoder-style ABS provision for vehicles equipped with wheel speed sensing
• Rectangular flange shape with defined pilot and flange dimensions for accurate fitment
• Designed to reduce downtime by combining the needed wheel-end components into one service assembly

Detailed Description

SKF BR931103 is a rear wheel bearing and hub assembly developed for Subaru rear wheel-end service. It is built around SKF’s wheel-end engineering and uses a HUB G3 bearing type with an encoder ABS configuration. The assembly includes the hub and bearing architecture needed for rear hub replacement on 2015-2021 Subaru Legacy, 2015-2021 Subaru Outback, and 2019-2021 Subaru Ascent models.

Dimension details include a 2.205 wheel pilot diameter, 2.283 brake pilot diameter, 3.3070 hub pilot diameter, 5.4330 flange diameter, and 5.4330 flange offset. The rectangular flange shape supports proper mounting geometry, while the angular contact bearing design is intended to improve hub stiffness and load handling compared with a conventional tapered bearing hub. Use BR931103 when servicing a Subaru Legacy rear wheel bearing hub assembly, Subaru Outback rear hub assembly, or Subaru Ascent rear wheel bearing replacement.

What This Part Helps Fix

• Rear wheel bearing noise or roughness
• Excessive hub play or looseness
• ABS wheel speed signal issues related to the encoder-equipped hub
• Uneven braking feel caused by worn rear hub components
• Vibration or instability from a worn rear wheel-end assembly

Installation Notes and Tips

Confirm rear position and vehicle application before installation. Inspect the knuckle, axle interface, and mounting surfaces for wear or corrosion before fitting the new hub assembly. Because this part uses an encoder ABS design, verify sensor alignment and wheel speed system operation after installation. For best results, follow Subaru service procedures and torque specifications during reassembly.

Quality Assurance

SKF has more than 100 years of wheel-end engineering experience, and BR931103 is manufactured to SKF quality standards for long service life and safety-focused performance. This part is built for consistent fitment and dependable rear hub service on Subaru Legacy, Subaru Outback, and Subaru Ascent applications.
