Overview
The ZF 2098.209.006 REAR AXLE SHAFT is a critical driveline component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational torque from the differential assembly directly to the wheel hubs, ensuring smooth power delivery under heavy load conditions. As a precision-machined shaft, it interfaces with the 2098109042: DIFFERENTIAL and the 2098309011: CROWN WHEEL to complete the final drive reduction. The SKU 2098.209.006 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit without modification. This axle shaft is housed within the rear axle casing and supports the 2099209001: DIFFERENTIAL assembly, making it indispensable for maintaining gear alignment and load distribution in commercial vehicle powertrains.
Symptoms of Failure
- Rear axle oil leakage near wheel hub: A worn 2098.209.006 shaft can damage the seal contact surface, causing gear oil to weep from the hub. This is a common long-tail search query for fleet maintenance teams.
- Vibration or shudder during acceleration: When the axle shaft splines wear, rotational imbalance occurs, leading to noticeable driveline vibration that intensifies under torque.
- Clunking noise from rear differential: Excessive play between the shaft and the 2098309010: DIFFERENTIAL HOUSING produces metallic knocking sounds, especially when shifting between drive and reverse.
- Uneven tire wear or wheel wobble: A bent or fatigued shaft causes lateral runout, resulting in premature tire degradation and steering instability at highway speeds.
