There isn't a single digit in a Chevrolet VIN that definitively indicates 4-wheel drive. The information about drivetrain (4WD, 2WD, AWD) is encoded within a combination of characters, usually found in the eighth position (sometimes also involving characters in positions 9 and 10). However, the specific code varies depending on the model year and model of the Chevrolet vehicle.
To determine if a specific Chevrolet vehicle is 4WD, you need to look up the VIN's decoding information using a VIN decoder (many are available online) or consult a Chevrolet parts and service manual for the specific vehicle year and model.
