Overview
This genuine ZF 2093.303.022 FLANGE BUSH is a precision-engineered component designed to provide a durable bearing surface and accurate alignment within the final drive assembly of heavy-duty construction machinery. Positioned between the axle shaft and the differential housing, this OEM bushing absorbs radial loads and reduces friction during high-torque operation. The part number 2093.303.022 is a direct factory replacement, ensuring exact fitment and material integrity for ZF transmissions operating under extreme stress. When installed alongside a DIFFERENTIAL HOUSING, this flange bushing maintains critical clearances that protect the entire drivetrain from premature wear.
Symptoms of Failure
- Oil seepage around the axle flange: A worn 2093.303.022 bushing allows the shaft to wobble, breaking the seal and causing transmission fluid to leak onto the undercarriage.
- Metallic grinding noise during turns: As the bushing wears thin, metal-on-metal contact occurs between the axle and the DIFFERENTIAL, producing a distinct low-frequency growl.
- Excessive driveline vibration at low speeds: Loss of bushing material creates play in the axle shaft, transmitting vibration through the chassis during loading cycles.
- Uneven tire wear on drive axles: Misalignment caused by a degraded flange bushing forces the differential to compensate, leading to scrubbing and accelerated tread loss.

Frequently Asked Questions
Q: Can I reuse the old spring pin when installing this flange bushing?
A: No. ZF recommends always replacing the SPRING PIN (0631329088) whenever the bushing is changed. The pin deforms during removal and will not provide the same retention force.
Q: How do I know if my transmission uses the 2093.303.022 bushing?
A: This bushing is standard in ZF WG180 and WG200 series final drives. If your machine has a planetary axle with a removable flange cover, this part is likely the correct one. Check the old bushing for the stamped part number.
Q: Will a worn bushing damage the differential housing?
A: Yes. A failed bushing allows the axle to contact the DIFFERENTIAL HOUSING, scoring the bore and requiring expensive housing replacement. Inspect the housing bore for galling whenever you replace the bushing.
