Critical fitment warning: The listing title identifies Honda Civic EX and Si, while the available compatibility text broadly states 2006–2011 Honda Civic without confirming trim or body style. Do not assume fitment for every Civic. Confirm the VIN, EX or Si trim where applicable, sedan or coupe body style, ABS configuration and connector, original rear hub dimensions, mounting pattern, and reference number before ordering.

Package Contents

The source identifies a wheel hub assembly but does not explicitly state the package quantity or confirm axle nuts, mounting bolts, clips, seals, dust shields, or other installation hardware. Review the product images and confirm the contents before ordering.

Installation Notes

Professional installation is strongly recommended. Wheel hubs are safety-critical components. Inspect the rear knuckle or spindle interface, ABS wiring and connector, brakes, wheel studs, tires, and related suspension parts. Clean and inspect all mating surfaces, route the ABS lead away from moving or hot components, and follow Acura or Honda torque procedures. Do not use an impact tool for final fastener torque. After installation, verify smooth rotation, correct wheel seating, brake operation, and that no ABS warning remains. Perform a controlled low-speed safety check before normal road use.
