Technician A says that one reason OEMs have eliminated the initial (break-in) lube drain on a new or rebuilt differential carrier is improved machining precision of current geartrain components.Technician B says that because synthetic gear lubes have superior ability to suspend abrasive contaminants,OEMs no longer require a break-lube change.Who is correct?

A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Geartrain Components

The individual parts that make up a geartrain, including gears, shafts, bearings, and casings, working together to transmit power in machinery.

Abrasive Contaminants

Hard particles or materials that can cause wear or scratching on surfaces they come into contact with, often found in working environments.

Machining Precision

The degree of accuracy and exactness in shaping parts by cutting, boring, drilling, or grinding, crucial for the proper functioning of mechanical systems.
