Aspligo Rear Wheel Bearing Hub Assembly for Subaru Outback 2010–2014 — Direct-Fit Forged Unit with Upgraded Seal

The Aspligo 512401 rear wheel bearing hub assembly is a direct-fit replacement engineered to meet OEM dimensions and restore rear-wheel stability for compatible Subaru, Scion and Toyota models.

This hub unit is designed as a complete rear wheel hub bearing assembly for a range of vehicles including Subaru Outback (2010–2014) and other compatible models. Built with upgraded forging and an improved sealing system, it aims to provide strength, corrosion resistance and consistent lubrication retention so the rear wheel operates smoothly under load and over rough roads. Before ordering, confirm fitment using your vehicle’s Year/Make/Model selection or check the OE interchange numbers listed below.

Will this hub assembly fit my car?

Compatibility is determined by year, make and model plus the OE interchange numbers. Aspligo 512401 lists several OE numbers and fits many Subaru platforms plus related Toyota/Scion vehicles; always verify the listed vehicle years and cross‑reference the part numbers to ensure a correct match.

• Compatible vehicles include Subaru Outback 2010–2014, Forester 2009–2013, Legacy 2010–2014, Impreza 2008–2014, Crosstrek 2019–2021, WRX/WRX STI models and BRZ/FR‑S/86/GR86 ranges.
• Check OE numbers: 28473AG000, 28473AG001, 28473AJ00A, 28473FG000 and others to confirm interchangeability.
• Installation location: rear wheel hub assembly — not for front axle use.

How is this hub assembly constructed and what upgrades does it have?

The Aspligo unit is produced using advanced forging processes that increase material strength and toughness, helping it withstand acceleration, braking and various axial or radial loads. It also includes an improved seal design to retain lubricant and resist corrosion, which extends service life under adverse road or load conditions.

• Forged metal construction for enhanced durability and structural integrity.
• Upgraded sealing to improve lubrication retention, heat dissipation and rust protection.
• Manufactured to meet OEM-sized tolerances for fit and function.

What are the key specifications and installation notes?

This hub assembly matches OEM geometry: it features a 5-lug wheel stud layout and the exact flange, pilot and brake pilot diameters required for compatible vehicles. Installation generally does not require bearing preload adjustment, but correct tools and procedures are essential to avoid damage; the unit should not be disassembled prior to fitting.

• Flange Diameter: 4.88 in; Bolt Circle Diameter: 3.94 in; Pilot Diameter: 3.31 in.
• Brake Pilot Diameter: 2.28 in; 5 wheel studs; 4‑bolt flange type; ABS sensor not included.
• Do not open or disassemble bearing; replace coaxially and use proper installation tools and torque values.

How will this part perform in real driving conditions?

The combination of robust forging and improved sealing helps the hub maintain alignment and reduce wear from road contaminants, which supports consistent wheel rotation and reliable load handling. While it restores mechanical fit and function, drive performance will also depend on surrounding components like bearings, studs and suspension condition.

• Designed to handle vehicle acceleration, braking forces and varying axial/radial loads.
• Enhanced corrosion resistance for longevity in wet or salty environments.
• Intended as a like‑for‑like replacement to maintain factory handling and wheel security.

Who is this for: The Aspligo 512401 rear wheel bearing hub assembly is suited for DIY mechanics, professional technicians and fleet owners who need a direct-fit, OEM-dimension replacement for rear hubs on supported Subaru, Scion and Toyota models. It’s appropriate when the original hub shows play, noise or wear, or when doing axle, brake or suspension service that requires a new rear hub unit. Always confirm vehicle fitment and OE cross-reference before purchase.
