Overview
The ZF 2097.211.021 REAR AXLE SHAFT is a critical torque-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational force from the differential assembly directly to the wheel hubs, ensuring precise power delivery under heavy load conditions. As a hardened steel shaft, it maintains axial alignment within the axle housing while withstanding high torsional stress. The SKU 2097.211.021 is precision-machined to OEM tolerances, making it a direct replacement for worn or damaged shafts in ZF driveline systems.
Symptoms of Failure
- Rear axle oil leakage near wheel hub: Worn shaft seals or surface scoring allow gear oil to escape, leaving visible drips on the brake drum or tire sidewall.
- Vibration during acceleration at highway speeds: A bent or fatigued shaft creates rhythmic shaking through the chassis, often mistaken for tire imbalance.
- Grinding noise from differential area when turning: Spline wear on the shaft end causes metal-on-metal contact with the 2093109021: DIFFERENTIAL side gears, producing a distinct growl.
- Intermittent loss of drive power: Stripped splines on the shaft fail to engage the 2093209096: DIFFERENTIAL unit, causing sudden wheel slip under load.

Compatibility
This rear axle shaft is designed exclusively for ZF WG-series powershift transmissions. Confirmed fitment includes the WG100, WG130, and WG131 models used in agricultural tractors and construction loaders. It interfaces directly with the 2093309073: DIFF.HOUSING and requires the 0750117075: TAPER ROLLER BEARING for proper axial support. Do not use this shaft in WG180 or WG200 series without verifying housing dimensions.

Frequently Asked Questions
Q: Can I install this shaft without replacing the taper roller bearing?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings accelerate shaft seal failure and cause premature spline wear.
Q: Will this part fit a ZF WG180 transmission?
A: No. The WG180 uses a longer axle shaft with a different spline count. Always verify your transmission model tag before ordering the 2097.211.021.
Q: How do I confirm the shaft is genuine OEM?
A: Authentic ZF parts have a laser-etched part number and a matte black oxide finish. Counterfeit shafts often show rough machining marks near the spline root.
