ZF 996 397 004 00 Axle Differential Output Seal

The ZF 996 397 004 00 is a genuine OEM axle differential seal designed to maintain a fluid-tight barrier at the differential output/axle interface. Manufactured by ZF — one of the world's leading suppliers of driveline and chassis technology — this seal is engineered to OEM specifications for precise fitment and long-term durability.

Differential output seals play a critical role in preventing gear oil from leaking past the axle shaft where it exits the differential housing. A worn or damaged seal can result in gear oil loss, leading to differential damage, increased wear on internal components, and potential drivetrain failure if left unaddressed.

Key Features:

• Genuine ZF OEM part — engineered to exact factory specifications
• Seals the differential output/axle shaft junction to prevent gear oil leakage
• Resistant to heat, gear oil, and the mechanical stress of rotating axle shafts
• Direct OEM replacement for proper fit without modification
• Manufactured by ZF, a globally recognized leader in driveline technology

Replacing a leaking differential seal promptly helps protect costly drivetrain components. This is a genuine ZF part, ensuring the same quality and performance as the original factory-installed seal.
