Technician B is correct because a ring gear tooth pattern check indeed indicates if the drive pinion depth is correct, which is essential for proper gear engagement and operation. Technician A's statement is incorrect because backlash (the clearance between the meshing teeth of gears) being okay does not necessarily mean that the side bearing preload (the force applied to bearings) is also okay; these are two separate adjustments.
