ZF 2099.109.046 DIFFERENTIAL | OEM Genuine Part

Overview

The ZF 2099.109.046 DIFFERENTIAL is a critical OEM genuine component designed for heavy-duty construction machinery transmissions. This differential assembly sits within the final drive housing, distributing torque evenly between the left and right axle shafts while allowing for speed differentiation during turns. As a core element of the drivetrain, the SKU 2099.109.046 ensures smooth power transfer and reduces tire scrub on uneven terrain. When paired with a robust DIFF.HOUSING, this part maintains precise gear alignment under extreme loads.

Symptoms of Failure

• Whining or grinding noise during turns: Worn internal gears cause audible friction, especially when cornering under load.
• Oil leaks near the axle housing: Degraded seals or housing cracks allow lubricant to escape, leading to contamination.
• Uneven tire wear or vibration: A failing differential disrupts wheel speed balance, causing premature tire scalloping and chassis shudder.
• Clunking on acceleration or deceleration: Excessive backlash from worn gear teeth produces metallic impact sounds.

Technical Specifications

Compatibility

This differential is engineered for ZF WG180, WG200, and WG310 series transmissions commonly found in wheel loaders, graders, and telescopic handlers. It directly replaces the earlier 2093209094: DIFFERENTIAL variant in many applications. For proper installation, ensure the SPRING PIN is correctly seated to prevent gear walk. The unit also interfaces with the DIFFERENTIAL AXLE for final torque delivery.
