A-Premium Rear Wheel Bearing and Hub Assembly 2-Pack (Rear, 5-Lug) — Pre-Greased Direct-Fit

A-Premium 2 x Rear Wheel Bearing and Hub Assembly is a direct-fit replacement 5-lug hub pair engineered to restore rear wheel stability and smooth rotation on compatible Subaru models.

This pair of pre-greased rear hub assemblies from A-Premium is designed to replace worn or noisy rear wheel bearings on a range of Subaru vehicles, including Forester (2014–2018), Impreza (select trims 2012–2021), and Crosstrek/XV Crosstrek models (2013–2021). Built with durable GCr15 and 65Mn steel, a four-hole flange and five wheel studs, these units accept the CV axle directly and match original equipment specifications to simplify installation and ensure proper fit with existing rotors, wheels, and nuts.

How will these hub assemblies address wheel noise and vibration?

If your vehicle exhibits unusual grinding, humming, or vibrations from the rear, worn bearings or damaged seals are often the cause. The A-Premium assemblies replace the bearing cage, seals, and spline interface to stop metal-on-metal wear and prevent grease leakage, helping eliminate the typical sounds and steering/wheel vibration associated with failing hubs.

• Includes new bearing cage and sealing components to stop lubricant loss.
• Pre-greased bearings reduce initial break-in noise and wear.
• Direct-fit splined hub accepts the CV axle to restore driveline smoothness.

Will these fit my Subaru model and how simple is installation?

These assemblies are made for rear-left and rear-right positions on specified Subaru model years and trims; compare the listed fitment to your vehicle before purchase. Because they match OE stud pattern, flange type, and spline interface, the hubs are a bolt-on replacement for mechanically competent DIYers or professional technicians using standard tools.

• Vehicle fitment: Forester 2014–2018, Impreza 2012–2014 (select trims), Impreza 2015–2021, Crosstrek 2016–2021 (select trims), XV Crosstrek 2013–2015.
• 5-lug stud pattern and 4-hole flange align with factory rotors and wheels.
• Pre-greased and ready to install—no separate bearing packing required.

What materials and specifications ensure durability?

A-Premium uses high-strength GCr15 bearing steel and 65Mn for key components to resist fatigue and wear under axial and radial loads. The wheel studs match original specifications for safe torque and fit, while the sealed design helps keep contaminants out and lubricant in for longer service life.

• Material composition: GCr15 steel bearing elements and 65Mn structural components.
• Wheel stud count: 5-lug; flange: 4-hole; axle spline: direct CV axle insertion.
• Reference part numbers: 512518, 28473FJ020 for cross-checking fitment.
