* Solid Front Axle: If it has a solid front axle (more common on 4x4 models), you're likely looking at a 1 1/16" (27mm) nut. However, it's *crucial* to verify this with a socket before attempting removal.
* Independent Front Suspension: If it has independent front suspension (more common on 2x4 models), the size will be different and likely smaller. You'll need to consult a repair manual specific to your truck's configuration to determine the correct size.
To find the correct size:
1. Consult a repair manual: A Haynes or Chilton manual for your specific year, model, and drivetrain will provide this information.
2. Check the truck: Carefully examine the nut itself. The size is usually stamped or cast into the nut, or you can measure it with calipers.
3. Use a socket set: Try a range of sockets until you find one that fits perfectly. Start with the 27mm if it's a 4x4, but be prepared to try other sizes.
WARNING: These nuts are very tight. You'll need a high-quality socket, a breaker bar, and potentially an impact wrench to remove them. Improper tools can easily damage the nut or the axle.
