Overview
The ZF 2098.340.061 LIFTING ARM is a critical OEM genuine component engineered for the final drive and axle assembly of heavy-duty construction machinery. This part functions as the primary mechanical interface between the transmission housing and the axle support structure, ensuring precise alignment and load distribution during high-torque operations. As a genuine ZF part, SKU 2098.340.061 guarantees exact fitment and metallurgical integrity, preventing premature wear in adjacent drivetrain components such as the 2098109042 DIFFERENTIAL and the 2098309011 CROWN WHEEL. Its robust design directly supports the 2099209001 DIFFERENTIAL assembly, making it indispensable for maintaining driveline rigidity under extreme loads.
Symptoms of Failure
- Abnormal axle housing vibration: A worn lifting arm causes misalignment, leading to rhythmic shaking during acceleration or turning, often misdiagnosed as a failing 2098309010 DIFFERENTIAL HOUSING issue.
- Oil seepage at mounting points: Cracks or deformation in the arm create gaps where transmission fluid escapes, leaving visible residue near the axle flange.
- Intermittent gear grinding noises: Loss of structural support allows the crown wheel and pinion to drift out of mesh, producing a metallic chatter under load.
- Uneven tire wear patterns: When the lifting arm fails to maintain proper axle geometry, the differential carrier shifts, causing accelerated scrub wear on drive tires.

Compatibility
This lifting arm is designed for integration with ZF’s WG180, WG200, and WG240 series transmissions commonly found in wheel loaders, telehandlers, and graders. It specifically mates with the 2098309009 DIFFERENTIAL HOUSING and the 2098309031 AXLE BEVEL GEAR assembly. For optimal drivetrain performance, it should be paired with the 2098309030 AXLE BEVEL GEAR and the 2098309032 DIFFERENTIAL BEVEL GEAR. Always verify axle serial numbers before installation, as variations exist between pre-2010 and post-2010 housing designs.
