Overview
The ZF 2097.117.018 REAR AXLE HOUSING is a structural core component within heavy-duty construction machinery drivelines. It encloses and supports the differential assembly, axle shafts, and final drive gears, ensuring precise gear alignment under extreme torque loads. As an OEM genuine part, SKU 2097.117.018 is engineered to withstand high stress from off-road applications, preventing housing distortion that leads to premature wear. This housing integrates directly with the 2097109012: DIFFERENTIAL and the 2093209096: DIFFERENTIAL to form a sealed, lubricated chamber for power transfer.
Symptoms of Failure
- Oil seepage at axle tube seals: Cracks or porosity in the housing cause lubricant loss, leading to insufficient gear lubrication.
- Whining or grinding noise during turns: Housing flexure misaligns the 0750117075: TAPER ROLLER BEARING, creating uneven gear contact.
- Vibration under load: Warped mounting surfaces allow the 2093309073: DIFF.HOUSING to shift, causing driveline shudder.
- Metal debris in differential fluid: Housing fractures generate metallic particles that accelerate bearing and gear failure.
