Overview
The ZF 2097.311.002 WHEEL STUD is a critical OEM genuine fastening component engineered for heavy-duty construction machinery drivelines. This stud secures the wheel hub assembly directly to the transmission output flange, ensuring precise torque retention and axial alignment under extreme load conditions. As a factory-spec part, the SKU 2097.311.002 is machined from high-tensile alloy steel to withstand the cyclic stresses of off-road operation. It sits at the interface between the axle shaft and the wheel end, working in concert with the 2093109002: DIFFERENTIAL to transfer rotational force without fastener fatigue.
Symptoms of Failure
- Wheel wobble or vibration at low speeds: A worn or stretched wheel stud allows lateral play in the hub, causing uneven tire wear and driver feedback through the steering wheel.
- Intermittent clicking during turns: When the stud loses clamping force, the wheel end can shift relative to the 2093209095: DIFFERENTIAL housing, producing metallic clicking sounds under load.
- Loose lug nut torque retention: If the stud threads are stripped or the shoulder is deformed, lug nuts will repeatedly back off even after proper torquing, indicating imminent fastener failure.
- Visible corrosion or cracking near the flange: Stress fractures or rust pitting on the stud shank signal material fatigue that can lead to catastrophic wheel separation.

Compatibility
This wheel stud is designed for ZF heavy-duty transmissions and drive axles commonly used in wheel loaders, graders, and excavators. It is a direct fit for the WG180, WG200, and WG310 series power shift transmissions. The stud also integrates with the 0750117075: TAPER ROLLER BEARING and the 2093309071: DIFF.HOUSING in final drive assemblies. Always verify thread pitch and shoulder length against your existing hub before installation.

Frequently Asked Questions
Q: Can I reuse the old wheel stud if it looks intact?
A: No. ZF recommends replacing wheel studs whenever the hub is disassembled. Even minor thread wear can lead to torque loss and eventual wheel separation under heavy construction loads.
Q: Does this stud require thread locker during installation?
A: Yes. Apply a medium-strength thread locker (Loctite 243 or equivalent) to the stud threads before torquing to the OEM specification of 450 Nm. This prevents loosening from vibration.
Q: Will this stud fit the WG180 transmission with a 10-bolt hub?
A: Yes. The 2097.311.002 is the correct OEM stud for WG180, WG200, and WG310 series hubs using M22 threads. Always confirm your hub bolt pattern and stud shoulder length before ordering.
