Overview
The ZF 2093.317.065 REAR AXLE HOUSING is a critical structural component engineered to encase and protect the differential assembly within heavy-duty construction machinery drivelines. This OEM genuine part serves as the rigid foundation that supports axle shafts and bearings, ensuring precise gear alignment under extreme torque loads. The SKU 2093.317.065 is specifically designed to withstand high-stress environments in wheel loaders and graders, functioning as the central hub that transfers rotational force from the transmission to the wheels. When paired with a 2093109029: DIFFERENTIAL, this housing maintains optimal gear mesh integrity during demanding operations.
Symptoms of Failure
- Hydraulic oil seepage from axle housing seals – Visible fluid accumulation around the housing mating surfaces indicates compromised structural integrity, often caused by thermal stress fractures or corrosion.
- Abnormal whining or grinding noise during turns – Worn housing bores allow excessive play in the 0750117075: TAPER ROLLER BEARING, producing metallic chatter that intensifies under load.
- Premature differential gear wear – Housing distortion misaligns the 2093209094: DIFFERENTIAL, causing uneven tooth contact patterns and accelerated pitting on ring and pinion sets.
- Vibration through the chassis at low speeds – Cracks in the housing casting create harmonic oscillations that resonate through the drivetrain, particularly noticeable during reversing maneuvers.

Compatibility
This rear axle housing is engineered for ZF WG180 and WG200 series power shift transmissions commonly deployed in construction machinery. It directly interfaces with the 2093309078: DIFF.HOUSING assembly and supports final drive configurations in models such as the WG180/200/220. The housing accommodates both standard and limited-slip differential carriers, making it suitable for Caterpillar, Volvo, and Case wheel loader applications requiring robust rear axle support.

Frequently Asked Questions
Q: Can the 2093.317.065 housing be repaired if cracked?
A: Welding is not recommended due to ductile iron’s heat-affected zone embrittlement. Replacement with this OEM genuine part ensures proper load distribution and avoids catastrophic failure.
Q: Does this housing include bearing races or seals?
A: No. The housing is supplied as a bare casting. You must install the 0750117075: TAPER ROLLER BEARING and appropriate oil seals separately.
Q: What is the typical service interval for this axle housing?
A: Under normal construction duty, inspect for cracks every 2,000 hours. Replace immediately if any deformation is detected to prevent damage to the 2093109029: DIFFERENTIAL assembly.
