Housing

Differential and main gear housings form a critical component of a vehicle's drivetrain, providing a secure enclosure for the gears and bearings that transfer power from the engine to the wheels. Located within the axle assembly, these housings protect internal components from contaminants and structural damage while maintaining proper gear alignment. Constructed from robust materials like cast iron or aluminum alloy, housings ensure durability under high stress and varying temperatures. Precise machining and sealing surfaces are essential for preventing leaks and maintaining lubrication. Examples within this Drivetrain > Differential & Main Gear > Housing category include housings for ZF differentials, such as part numbers 4481-371-180, 4481-371-179, and 4061-316-181, used in a variety of passenger and commercial vehicle applications.
