Common Problems This Part Can Address

• Wheel bearing noise from the front axle area
• Steering vibration or wheel shake at speed
• Brake pulsation related to hub runout
• ABS warning light caused by wheel-speed signal issues
• Uneven wheel rotation or looseness at the hub

Installation Notes and Tips

Verify bolt circle diameter, wheel pilot diameter, and brake pilot diameter before installation to confirm the correct BMW front hub application. Clean the mounting surface thoroughly and inspect adjacent suspension and brake components for wear that could affect hub performance. Because this assembly is used on non-driven front positions, confirm the vehicle configuration matches the listed fitment before ordering.
