What size is the axle nut on a Honda Accord?
The typical front axle nut on many Honda Accord models is 30 mm across flats, though some years use a 32 mm nut. Rear axle nut sizes vary by generation. For exact specs, check your specific year and drivetrain in the factory service manual or a trusted parts database.
Why the size isn’t universal
Honda redesigned hub assemblies and CV joints across generations. As a result, the axle nut diameter and head size have changed in some model years. The front axle nut secures the CV axle to the wheel hub; the rear axle design can differ more between generations, sometimes requiring a different size.
Common front axle nut sizing
In most Accord generations, the front axle nut across flats is 30 mm. Some model years or trims may require a 32 mm nut. To be certain, refer to the year-specific service manual or a parts database by VIN.
Before selecting a tool, ensure you know the exact year and drivetrain. The front axle nut is most often 30 mm across flats but can be 32 mm on particular variants.
Rear axle nut sizing
Rear axle nut diameter varies more by generation and whether the car uses a particular suspension or drivetrain setup. Many older Accords used a smaller rear hub nut, while newer generations may differ. Verify the exact size for your year and model in the service manual or official parts catalogs.
With the rear axle, the size is less standardized across generations, so checking the manual is essential before attempting work.
How to verify the correct size for your car
Use these practical verification methods before attempting maintenance:
- Consult the owner's manual or factory service manual for your year, engine, and drive type to find the exact axle nut size and any locking features.
- Inspect the existing nut: if you have the nut off or can view it, measure the distance across flats with a ruler or caliper to determine the correct size.
- Ask at a Honda dealership or a reputable auto parts store with your vehicle’s year, model, and drivetrain; staff can confirm the correct nut size quickly.
- Check reliable online databases or forums that list year-by-year hardware specs for Honda Accords.
Using the exact size ensures you’ll use the proper socket and avoid rounding the nut or damaging the hub. Always verify with official documentation for your specific car.
Summary
In short, the front axle nut on many Honda Accords is 30 mm across flats, with some generations using 32 mm. Rear axle nut sizes vary more by generation. The most reliable approach is to confirm the exact size and any torque requirements from your model’s factory service manual or a trusted parts database that matches year, engine, and drivetrain.
