What size is the axle nut on a 2004 Chevy blazer?

The size of the axle nut on a 2004 Chevy Blazer depends on whether it's a 2WD or 4WD model, and even then, there might be slight variations depending on the specific axle assembly. There's no single definitive answer.

To find the correct size, you need to:

1. Consult your owner's manual: This is the best place to start. It should specify the size in the specifications section or the maintenance section.

2. Check the nut itself: If you can access the axle nut, you can measure it with a socket wrench or caliper. This is the most reliable method.

3. Use a repair manual specific to your Blazer's year, make, and model: A Haynes or Chilton manual will often list the size.

4. Check online parts stores: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to search for parts based on your vehicle's VIN or details. Looking up axle nuts for your specific Blazer model will reveal the size.

Without knowing the specific details of your Blazer (2WD or 4WD, specific trim level, etc.), it's impossible to provide the correct axle nut size.
