Overview
The ZF 2094.117.005 REAR AXLE HOUS. is a critical structural component designed to encase and protect the differential and final drive gears within ZF heavy-duty powertrains. Positioned at the output end of the transmission assembly, this OEM genuine housing absorbs immense torsional loads and maintains precise gear alignment under extreme operating conditions. As a genuine ZF part, SKU 2094.117.005 ensures factory-specified tolerances for durability in construction machinery applications. This housing works in concert with the 2094101011: TRANSMISSION HOUSING to form a sealed, rigid chassis for the entire driveline system.
Symptoms of Failure
- Persistent oil seepage from axle seals: When the rear axle housing develops hairline cracks or warpage, lubricant escapes past the 0750111371: SHAFT SEAL, leaving visible drips under parked equipment.
- Abnormal whining or grinding during turns: A compromised housing allows differential bearing preload to shift, creating metal-on-metal noise that intensifies under load.
- Premature gear tooth wear: Misalignment caused by a fatigued housing accelerates wear on ring and pinion sets, often detected during routine oil analysis.
- Vibration through the chassis at low speeds: Structural flex in the housing transmits harmonic vibrations that are absent with a rigid, undamaged unit.

Compatibility
This rear axle housing is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, graders, and heavy forklifts. It directly fits the WG180 and WG200 transmission families, as well as certain variants of the WG150 series. For proper sealing, always install a new 0634303085: O-RING and 2094301030: GASKET during replacement. The housing interfaces with the 2094301045: HOUSING and is secured using 0636011356: HEXAGON SCREW fasteners. A 0635460022: BALL is used in the detent mechanism, while the 2094301044: COVER protects the access port. Additional alignment is provided by the 0631306670: CYLINDRICAL PIN, and the fill/drain port uses a 4475280060: SCREW PLUG.
