What size is the hub nut on a Toyota Hilux?
The hub nut size on a Toyota Hilux is not universal; it varies by model year and drivetrain. In practice, many Hilux front hubs use a hex size in the 30–32 millimeter range, but you should verify against your exact vehicle specification.
This article explains why hub-nut sizes differ across Hilux generations, how to identify the correct size for your specific truck, and steps you can take if you need to replace the nut or its retaining hardware. The information aims to help owners and technicians avoid damage from using an incorrect socket or torque.
Understanding hub nuts on the Hilux
The hub nut, or axle nut, secures the wheel hub to the axle and helps preload the bearing. Different Hilux generations used variations in hub hardware, so the exact hex size can shift between older and newer models, as well as by market or trim level. Using the correct size is essential to avoid rounding the nut, damaging the hub, or compromising bearing preload.
Common hub-nut sizes seen on Hilux fronts
Because the Hilux has evolved across generations, the hex size on the front axle nut has varied. The following sizes are commonly reported by technicians and owners, but you should confirm with the exact vehicle documentation for your year and market.
- Older Hilux generations (late 1990s to early 2000s) commonly use a 30 mm hex axle nut.
- Many newer Hilux models (mid-2000s to present) commonly use a 32 mm hex axle nut.
Sizes can vary by market, trim, and any mid-cycle updates, so always verify with the service manual or dealer for your specific vehicle.
How to confirm your vehicle's exact size
To avoid guesswork, follow these steps to identify the correct hub-nut size for your Hilux without risking damage.
- Refer to the official Toyota Hilux service manual for your vehicle’s VIN; locate the wheel hub/axle section to find the axle nut size.
- Check the OEM parts diagram or Toyota Genuine Parts catalog for your year and market; the diagram will list the axle nut size and part number.
- Physically measure the nut: try sockets that fit snugly across the flats to determine the correct hex size, or use a hex gauge to confirm the exact measurement.
- When in doubt, contact a Toyota dealer or a trusted mechanic with access to VIN-specific data for the precise specification and torque value.
Knowing the exact size ensures you use the correct tool and avoid rounding the nut or injuring the wheel bearing assembly during removal or installation.
Safety and installation notes
Always follow a manufacturer’s torque specifications when reinstalling the axle nut, and use a new nut and any required locking washer or cotter pin as specified for your model. If you’re unsure about the size or torque, seek professional service rather than improvising with a mismatched socket.
Summary
The hub nut size on a Toyota Hilux is not a one-size-fits-all detail; it typically falls in the 30–32 mm hex range, but exact sizing depends on the generation, market, and drivetrain. To ensure proper fit and bearing preload, verify the size against your vehicle’s service manual, factory diagrams, or a dealer with your VIN. When replacing, use the correct nut and follow the specified torque values to maintain safety and performance.

What size socket fits a Toyota axle nut?
The most common Toyota axle nut socket size is 39mm, but the size can vary depending on the specific model and year. Some older 4WD Toyota models may use a larger 54mm socket, while other vehicles like certain Tacomas can use a 30mm socket. It's essential to confirm the exact size for your vehicle before purchasing a socket.
Common sizes
- 39mm: This is the most common size for many modern Toyota trucks, SUVs, and cars.
- Specific examples include the 2007-2010 Sequoia, Tundra, and 2008-2010 Land Cruiser.
- 54mm: Used for many older 4WD models such as the 4Runner (1986-1995), Land Cruiser (1975-2007), and Pickup Truck (1979-1995).
- 30mm: Found on certain vehicles like the 2012-2017 Toyota Camry.
- 28mm: Used on some Tacoma models, such as the 1995-2000 4WD versions.
Before you begin
- Confirm your vehicle's specific size: Always verify the correct size for your vehicle's make, model, and year.
- Get the right type: Many Toyota axle nuts use a 12-point socket, but some smaller, older ones may use a 6-point socket.
- Note the length: Axle nuts can be recessed, so a deep-well socket is often necessary.
- Consider impact sockets: Using a high-quality, impact-grade socket is highly recommended for loosening or tightening these very tight nuts, suggests this YouTube video and this YouTube video.
