ZF 5838.117.012 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.117.012 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine housing encloses the differential gear set and supports the axle shafts, ensuring precise alignment under extreme torque loads. The SKU 5838.117.012 serves as the rigid backbone that absorbs torsional stress and maintains proper gear mesh, directly influencing drivetrain durability. When paired with a 5838109006: DIFFERENTIAL, this housing forms the sealed chamber that protects internal components from debris and contamination.

Symptoms of Failure

• Hypoid oil seepage at housing seams: Cracks or porosity in the casting cause gear oil to weep from the axle housing flanges, leaving visible residue on the chassis.
• Abnormal whining or howling during turns: A worn housing bore allows the 0750117075: TAPER ROLLER BEARING to shift, creating uneven gear contact patterns and audible distress.
• Increased backlash in the final drive: Housing distortion from fatigue loading permits excessive play between the ring gear and pinion, leading to driveline clunking on acceleration.
• Metallic debris in differential oil: Internal spalling of the housing surface contaminates the lubricant with ferrous particles, accelerating wear on the 2095209037: DIFFERENTIAL assembly.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG-series powershift transmissions commonly deployed in wheel loaders, graders, and telehandlers. Verified fitments include the WG180, WG200, and WG210 models. It also integrates with the 4482360002: AXLE BEVEL GEAR and 5838300811: THRUST WASHER for complete final drive restoration. Always cross-reference the OEM tag on your existing housing before ordering.
