The KUSATEC 512401 is a direct-fit rear wheel bearing and hub assembly engineered as a factory-style replacement for compatible Subaru, Scion FR-S and Toyota 86 models.

This replacement hub assembly restores rear wheel mounting, smooth rotation and secure wheel fastening for vehicles that list part number 512401 or equivalent references. Manufactured from medium carbon steel with improved sealing and protective-coated hub bolts, this assembly is designed to meet OEM dimensions and fitment for rear-left and rear-right positions where a 5-lug, 27-spline hub with M12x1.25 flange bolts is required.

Will this hub assembly fit my car?

This KUSATEC hub is produced according to OEM dimensional standards and inspected at the factory to ensure compatibility and consistent operation. The design focuses on matching bolt pattern, spline count and pilot dimensions so the wheel and brake components seat correctly.

• PCD: 100.2mm; flange bolt thread: M12x1.25; number of flange bolt holes: 4
• Material: medium carbon steel for durable hub life and strength
• Sealing improved to reduce contamination and lower noise or vibration

What are the notable quality and installation features?

KUSATEC supplies a finished hub with protective-coated bolts and enhanced seals to simplify installation and resist corrosion. The product photos are real shots of the actual unit so installers can verify appearance and key features before purchase.

• Protective coating on wheel hub bolts helps prevent rust and eases wheel nut torqueing
• Factory inspection to meet OEM-style tolerances and reduce runout
• Designed for stable operation with minimized noise and vibration
• Direct-replacement form factor—intended for straightforward bolt-on installation

Do I need special tools or parts to install it?

Standard wheel-hub service tools are typically sufficient, but follow vehicle-specific service manual steps for torque values and installation order. If your vehicle uses an ABS sensor assembly mounted separately, ensure that ring and sensor alignment are correct after replacement.

• Common tools: jack, stands, torque wrench, socket set and breaker bar
• Confirm torque specs from your vehicle manual for M12x1.25 flange bolts and wheel nuts
• ABS: this unit ships without an ABS sensor—reuse factory sensor or install compatible sensor if required
• Visual check: verify hub pilot (56mm) and brake pilot (58mm) seating before final torquing
