ZF 2098.109.003 DIFFERENTIAL | OEM Genuine Part

Overview

The ZF 2098.109.003 DIFFERENTIAL is a critical power distribution component engineered for heavy-duty construction machinery transmissions. This OEM genuine part sits within the final drive assembly, precisely transferring torque from the driveshaft to the axle shafts while allowing the wheels to rotate at different speeds during turns. The SKU 2098.109.003 is designed to withstand extreme loads and thermal stress in demanding environments such as wheel loaders, graders, and dump trucks. It integrates directly with the 2098117002: HOUSING and the 2098301052: REAR AXLE HOUS. to form a sealed, lubricated assembly that ensures smooth operation and long service life.

Symptoms of Failure

• Whining or howling noise during turns: Worn differential gears produce a distinct metallic whine when cornering, often indicating excessive backlash or pitting on the gear teeth.
• Oil leaks near the axle housing: A failing differential can cause fluid seepage past seals, leading to low lubricant levels and accelerated wear. This is commonly noticed as wet spots around the REAR AXLE HOUS..
• Vibration or shudder under load: Damaged spider gears or a cracked differential case create driveline vibration, especially when accelerating or climbing grades.
• Uneven tire wear or wheel hop: Internal binding or excessive clearance in the differential causes inconsistent power delivery, resulting in premature tire wear and jerky movement.

Technical Specifications

Compatibility

This differential is primarily used in ZF WG180, WG200, and WG310 series transmissions found in construction machinery. It also fits select models of the ZF 4WG-200 and 6WG-200 power shift transmissions. The part is designed to work with the 0636103300: STUD and 0637101164: HEXAGON NUT for secure mounting to the housing. Always verify your transmission model and axle configuration before ordering.
