Overview
This OEM genuine ZF 2093.304.022 GEAR is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the final drive assembly, this gear transfers rotational force from the differential to the axle shafts, ensuring smooth torque delivery under heavy loads. The SKU 2093.304.022 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged gears in commercial vehicle drivelines. When installed alongside a 5838109012: DIFFERENTIAL, this gear maintains proper mesh alignment and reduces backlash in the gear train.
Symptoms of Failure
- Whining or howling noise during acceleration: A worn 2093.304.022 gear produces a distinct high-pitched whine that intensifies under load, often mistaken for wheel bearing noise. This indicates tooth surface pitting or misalignment.
- Intermittent gear slipping under heavy torque: When the gear teeth lose their hardened profile, the transmission may momentarily lose drive engagement, especially when climbing grades or hauling maximum payloads.
- Metallic debris in differential oil: Flakes or silver-colored particles in the lubricant signal advanced wear of the gear’s tooth flanks. This symptom often accompanies failure of the 0750117075: TAPER ROLLER BEARING, which supports the gear shaft.
- Vibration through the chassis at highway speeds: Uneven gear wear creates rotational imbalance, transmitting vibration through the driveline and into the vehicle frame.

Compatibility
This gear is specifically designed for ZF WG100, WG130, and WG131 transmissions found in medium-duty trucks, buses, and agricultural machinery. It also fits select variants of the WG180 and WG200 series when used with the 2093209023: DIFFERENTIAL assembly. Always verify the tooth profile and shaft spline count against your existing component. The gear interfaces directly with the 5838300626: DIFFERENTIAL HOUSING to maintain proper axial clearance.

Frequently Asked Questions
Q: Can the 2093.304.022 gear be used in a ZF WG180 transmission without modification?
A: While the gear shares tooth geometry with WG180 variants, we recommend comparing the shaft spline count and overall diameter. Some WG180 units require a different differential housing, such as the 5838300626, to accommodate this gear.
Q: What torque specification should be used when installing this gear?
A: The retaining nut should be torqued to 280-320 Nm (207-236 lb-ft) when using a new spring pin (0631329088). Always replace the thrust washers (5838300811, 5838300753, or 5838300818) during installation to prevent premature wear.
Q: How do I identify if my gear is the 2093.304.022 or a different variant?
A: Measure the outside diameter (142 mm) and count 37 teeth. The part number is also stamped on the gear’s inner bore. If the gear shows pitting on more than 15% of tooth surfaces, immediate replacement is required.
