TECHNICIAN 2 IS CORRECT.
Wheel bearing is typically used for guiding and supporting shafts and sometimes axles. Wheel bearing has its own special grease, which is specifically designed for high friction surfaces. Most bearing wheels in cars and trucks are typically lubricated with NLGI {National Lubricating Grease Institute] Number 2.  Effective lubrication is needed to ensure that a wheel bearing has a long life.
