Overview
The ZF 2095.117.046 REAR AXLE HOUS. is a critical structural component designed to encase and protect the differential and final drive gear set within ZF heavy-duty transmissions. As an OEM genuine part, this housing serves as the rigid backbone for the rear axle assembly, absorbing torsional loads and maintaining precise gear alignment under extreme operating conditions. The SKU 2095.117.046 is specifically engineered for construction machinery applications, ensuring that the differential gears and bearings remain securely positioned during high-torque operations. This housing directly interfaces with the 2095309059: DIFF.HOUSING to create a sealed environment that prevents contamination while supporting the 2095109020: DIFFERENTIAL assembly.
Symptoms of Failure
- Visible oil seepage at axle seals: When the rear axle housing develops stress fractures or porosity, hydraulic fluid escapes, leaving wet patches around the hub or differential cover. This is a common “axle housing oil leak” issue in ZF WG transmissions.
- Unusual whining or grinding noises: A cracked or warped housing allows the 0750117075: TAPER ROLLER BEARING to shift out of alignment, producing a rhythmic metallic sound during turns or under load.
- Premature differential gear wear: Misalignment caused by a deformed housing accelerates tooth surface fatigue on the 2095209037: DIFFERENTIAL components, leading to reduced power transfer efficiency and eventual gear seizure.
- Vibration through the chassis: A compromised housing cannot dampen driveline oscillations, resulting in noticeable shaking at speeds above 15 mph, often misdiagnosed as wheel imbalance.

Compatibility
This rear axle housing is primarily designed for ZF WG180, WG200, and WG250 series transmissions used in wheel loaders, telehandlers, and graders. It also fits select ZF 4WG-200 and 6WG-250 power shift transmissions manufactured between 2008 and 2020. The housing accommodates both standard and limited-slip differential configurations. Always verify the axle flange pattern against your existing unit before installation.
