How can you tell 2004 Nissan Xterra 4 wheel drive?

To determine if a 2004 Nissan Xterra is equipped with four-wheel drive (4WD), check for a 4WD shift lever or button inside the vehicle, typically located near the gear shifter. You can also look for markings on the rear of the vehicle, such as "4WD" or "4x4," which indicate its drivetrain type. Additionally, inspect the vehicle's owner manual or check the VIN (Vehicle Identification Number) for drivetrain specifications. Lastly, examine the undercarriage for a transfer case, which is part of the 4WD system.
