ZF 4481.333.048 DIFFERENTIAL AXLE | OEM Genuine Part

Overview

The ZF 4481.333.048 DIFFERENTIAL AXLE is a critical OEM genuine component engineered for the demanding environment of construction machinery. This part functions as the primary torque distribution unit within the final drive assembly, allowing the left and right wheels to rotate at different speeds while maintaining traction during turns and uneven terrain operation. As a genuine ZF part, SKU 4481.333.048 ensures precise gear mesh and load-bearing capacity, directly influencing the stability and efficiency of heavy equipment transmissions. It sits between the axle housing and the planetary gear set, converting rotational power from the driveshaft into usable wheel motion while absorbing significant torsional stress.

Symptoms of Failure

When the ZF 4481.333.048 differential axle begins to fail, operators may notice grinding noises during turns—a clear indicator of worn gear teeth or bearing surfaces. Another common symptom is uneven tire wear or wheel hop, often caused by differential case distortion or spider gear degradation. Oil leaks from the axle housing seals frequently accompany failure, as the differential axle’s movement can compromise adjacent gaskets and housings. Finally, slipping or delayed engagement when shifting from forward to reverse suggests the differential axle is no longer maintaining proper preload, leading to power loss under load.

Technical Specifications

Compatibility

This differential axle is designed for integration with ZF’s heavy-duty transmission families, specifically the WG180 and WG200 series, which are common in wheel loaders, graders, and dump trucks. It also fits select models within the WG150 and WG250 ranges where differential axle dimensions match. For precise fitment, always verify the axle housing and gear ratios; the 4481.333.048 is typically paired with a 4.56:1 or 5.13:1 final drive ratio.
