On a 2002 Chevy Silverado/Sierra 1500 (assuming that's the truck you mean by "2 2002 Chevy truck") with a V6 engine, the drive wheel configuration depends on whether it's a 2WD or 4WD model:
* 2WD: The drive wheels are on the rear axle.
* 4WD: All four wheels are drive wheels.
There is no single "drive wheel side" in the 4WD configuration.
