Autoround front wheel hub & bearing assembly for Toyota Corolla 2009–2019 — 5‑lug, integrated ABS tone ring, direct fit

The Autoround 512403 is a ready-to-install front wheel hub and bearing assembly engineered to replace the factory unit on Toyota Corolla (2009–2019), Pontiac Vibe (2009–2010) and Toyota Matrix (2009–2014).

This complete hub-and-bearing unit integrates the wheel hub, bearing and ABS tone ring into a single, pre-assembled part designed for a direct fit where the OE specification calls for a 5-lug, ABS-equipped hub with a 135 mm flange diameter and 74 mm hub pilot diameter. Autoround supplies this assembly as a quality-tested aftermarket replacement intended to restore wheel alignment, reduce noise and vibration, and simplify installation compared with pressed-in bearing repairs.

How does the 512403 assembly match OE fit and function?

The 512403 is manufactured to the critical dimensions and mounting geometry used by the original equipment so it installs without modification on compatible models. It includes the integrated ABS tone ring and mounting flange that match the factory bolt pattern and hub seat.

• 5 lug configuration for direct bolt-on replacement
• Flange diameter: 135 mm and hub pilot diameter: 74 mm
• Bolt circle diameter: 100 mm to align with factory studs
• Built-in ABS sensor ring for compatibility with vehicle anti-lock systems

What are the performance and durability features?

Autoround wheel hub assemblies undergo quality testing to meet or exceed OEM performance tolerances for bearing preload and rotational runout. The sealed bearing design helps keep contaminants out and lubricant in, extending service life under normal driving conditions.

• Sealed unit reduces maintenance and contamination risk
• Precision-machined mounting surfaces for consistent wheel runout
• Durable bearings and corrosion-resistant flange coating
• Manufactured to meet OEM-style dimensional and load requirements

How does installation compare to replacing just the bearing?

Because the 512403 ships fully assembled, it eliminates the need for a press or special bearing tools required to remove and install separate press-fit bearings. This reduces labor time and the risk of introducing alignment errors during installation.

• Pre-assembled hub and bearing—no pressing required
• Saves technician time and simplifies roadside repairs
• Direct bolt-on with existing wheel studs and mounting holes
• Includes ABS ring so electrical components remain compatible

Will this assembly work with my vehicle’s ABS and braking components?

Yes. The assembly includes an ABS tone ring designed to interface with the original ABS sensor on the listed models, preserving wheel speed signal accuracy for the anti-lock braking system. Always verify part compatibility with your VIN or existing hub dimensions before purchase.

• Integrated ABS tone ring for correct sensor readings
• Compatible with factory calipers and rotors when installed properly
• Designed to maintain original wheel speed signal integrity

Who is this for: The Autoround 512403 wheel hub and bearing assembly is intended for DIY mechanics, professional technicians, and fleet managers seeking a reliable, OE-dimension replacement for Corolla (2009–2019), Pontiac Vibe (2009–2010) and Matrix (2009–2014) front hubs. Choose this unit if you want a pre-assembled, ABS-ready hub that reduces installation time and restores proper wheel mounting geometry without pressing new bearings.
