ZF 2093.317.029 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2093.317.029 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encases the differential and axle shafts, providing the rigid support necessary to transmit torque from the transmission to the wheels while withstanding extreme loads and shock from uneven terrain. The housing also serves as a reservoir for lubricating oil, ensuring all internal gears and bearings operate under optimal conditions. As a direct replacement for the original equipment, SKU 2093.317.029 guarantees precise fitment and metallurgical integrity, preventing misalignment that can lead to premature wear of internal components like the 2093109024: DIFFERENTIAL.

Symptoms of Failure

When the ZF 2093.317.029 rear axle housing becomes compromised, operators will notice distinct performance issues. Oil leaks around the axle seals or housing mating surfaces are the most common early indicator, often caused by hairline cracks or porosity in the casting. A second critical symptom is unusual gear whining or grinding noises from the rear axle, which occurs when the housing has warped, allowing the 0750117075: TAPER ROLLER BEARING to lose its preload. You may also experience vibration during acceleration or turning, a sign that the housing’s mounting points have fatigued, leading to driveline imbalance. Finally, contaminated or metallic debris in the axle oil indicates internal wear from a cracked housing that has allowed foreign particles to enter the assembly.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF’s heavy-duty transmission series commonly found in wheel loaders, graders, and dump trucks. It is a direct fit for the ZF WG180 and ZF WG200 power shift transmissions, as well as the ZF 4WG-200 series. The housing also integrates with the ZF 5WG-210 series used in larger articulated haulers. When replacing this housing, it is essential to also inspect the 2093209095: DIFFERENTIAL and the 2093309071: DIFF.HOUSING for wear, as these components share the same load path.

Frequently Asked Questions

Q: Can I install this housing without replacing the bearings?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING whenever the housing is swapped, as old bearings may have worn unevenly against the damaged housing, leading to premature failure of the new part.

Q: What causes cracks in the rear axle housing?
A: The most common cause is repetitive shock loading from operating on uneven terrain, combined with loose axle mounting bolts that allow the housing to flex beyond its design limits. Always torque bolts to factory specifications.

Q: Does this housing come with pre-installed seals?
A: No, the housing is supplied as a bare casting. You will need to install new oil seals and the 0631100223: SPRING PIN separately to ensure a leak-free assembly.
