What size is the hub nut on a Hilux?
Hub nut size on a Toyota Hilux isn’t a fixed figure across all models. Front axle hub nuts are typically around 30–32 mm across flats, but the exact size depends on the generation, market, and axle design.
Over the Hilux’s many generations and regional variants, wheel hub assemblies can differ. To be certain, refer to the specific service manual for your year and market or measure the nut directly. The following guide outlines common sizes and how to verify them for your vehicle.
Identifying the correct size for your Hilux
Hub nuts are usually described by their across-flats measurement. The sizes you’re most likely to encounter on front hubs are:
- 30 mm across-flats
- 32 mm across-flats
- 34 mm across-flats (less common, on some older or region-specific variants)
Note that some Hilux front hubs use different mounting hardware or locking mechanisms (such as ABS variations or 4x4 configurations), which can affect the exact nut required. Always verify the correct size before purchasing or installing a replacement.
How to confirm your exact hub nut size
To avoid ordering the wrong size, verify with direct measurement and official documentation. Use the following steps:
- Check the owner’s manual or workshop manual for your exact model-year and market specification.
- Inspect the existing hub nut with a caliper or ruler to measure across flats—the distance across the two parallel sides of the nut.
- If the old nut is available, bring it to an auto parts store or Toyota dealer to match the size in person.
- Confirm whether your Hilux uses a cotter pin, locking tab, or thread-locking compound, as this can influence installation and re-torque requirements.
After confirming the correct size, follow the service manual’s torque specification and any retorque or safety procedures to ensure proper wheel attachment.
Notes on installation and safety
Using the wrong hub nut size or improper torque can lead to wheel detachment or hub damage. If you’re unsure, have a qualified mechanic perform the replacement and any subsequent alignment checks. The front hub assembly is critical to wheel security and braking performance on the Hilux.
Summary
The hub nut size for a Toyota Hilux varies by generation and drivetrain configuration. Common sizes you may encounter are 30 mm, 32 mm, or occasionally 34 mm across flats. Always verify with your vehicle’s manual or by measuring the nut directly, and follow the manufacturer’s torque and installation guidelines for safe operation.
