What size is the axle nut on a 1999 Toyota Camry?
The axle nut on the front wheels of a 1999 Toyota Camry generally uses a 30 mm socket across flats. Always verify for your exact vehicle before work, as there can be small variations.
In the 1999 Camry, part of the XV20 generation, the outer CV joint on the front axle is secured by an axle nut that is typically a 30 mm hex size. While 30 mm is the common standard for this model year, production tolerances or aftermarket parts can lead to slight differences. This article outlines how to confirm the correct size and what to do if your nut differs.
How to verify the correct axle nut size
To avoid damage and ensure you have the right tool, follow these steps to confirm the exact size for your vehicle:
- Check the factory service manual or the official Toyota repair guide for the exact nut specification and any related torque instructions for your trim and drivetrain.
- Visually inspect the nut and measure the distance across flats (the width from one flat edge to the opposite flat edge) with a caliper or a ruler to determine the hex size in millimeters.
- Attempt a test fit with a socket from your toolkit, starting with a 30 mm socket and trying slightly larger or smaller sizes if the fit isn’t right, to avoid rounding the nut.
- If you’re replacing the nut, use a genuine OEM or OEM-spec fastener and follow the manual for any washer, temperature treatment, or thread-lock requirements.
- If you’re unsure, contact a dealership or parts supplier with your VIN to confirm the exact nut size for your specific vehicle configuration.
In practice, most 1999 Camry front axle nuts will fit a 30 mm socket. If you find a different size, stop and verify with the service manual or measure the nut directly before proceeding with removal or replacement.
Summary
For a 1999 Toyota Camry, the front axle nut is typically 30 mm across flats. Always verify against the vehicle’s repair documentation or measure the nut to confirm the exact size before performing maintenance. Proper sizing helps prevent tool damage and ensures proper hub retention.
