Technical Details and Specifications

The FAG 103332 wheel bearing and hub assembly is designed with exacting tolerances to match BMW factory specifications. The 5-lug wheel stud pattern with a bolt hole diameter of 112 mm (4.409 inches) supports secure wheel mounting. The brake pilot diameter of 67 mm (2.638 inches) ensures the brake rotor seats correctly, reducing vibration and wear. The hub pilot diameter of 98 mm (3.858 inches) centers the hub on the axle flange, maintaining alignment and reducing stress on suspension components. The flange diameter of 140 mm (5.512 inches) with four inlet mounting holes provides a stable connection to the knuckle. Additionally, the included ABS tone ring with a multipol encoder (MPE) supports the vehicle’s anti-lock braking system by delivering accurate wheel speed data.

Applications and Problem Resolution

• Replaces worn or damaged wheel bearing and hub assemblies on compatible BMW models
• Addresses wheel vibration or noise caused by bearing wear
• Restores proper ABS sensor function with integrated tone ring
• Corrects wheel alignment issues related to hub pilot wear
• Eliminates brake rotor misalignment due to damaged brake pilot diameter

Installation Notes and Tips

Ensure the hub assembly is installed using proper torque specifications for the wheel studs and mounting bolts. Verify the ABS tone ring is correctly positioned to avoid sensor errors. Clean the mounting surfaces thoroughly before installation to prevent contamination and ensure accurate fitment. It is recommended to inspect related suspension and brake components during replacement to maintain overall system integrity.
