1402-9048 – Flange Yokes – 1100 Series – Bolt Circle Dia 2.910″ – Pilot Dia 1.840-F

The 1402-9048 flange yoke mounts to the companion flange or axle housing and carries the driveshaft end u-joint. It's not a universal part — the bolt circle, pilot diameter, and series are all specific. Vibration that tracks with vehicle speed and stays consistent under load often starts right here, at a worn or mis-seated flange yoke. The 1402-9048 flange yoke is the correct replacement.

1402-9048 Flange Yoke — 1100 Series Specifications & Fitment

The 1100 series covers light-duty PTO and agricultural drive. The 1402-9048 flange yoke specs: 2.910 bolt circle | 1.840-F pilot | 4x0.315 bolt holes | 1.500" CJ-to-flat. Pilot diameter is what centers the yoke on the companion flange — that dimension must match exactly or the driveshaft will run off-center at speed. Bolt circle determines your hole pattern match.

Before ordering the 1402-9048 flange yoke, measure your diff flange bolt circle and pilot diameter directly. Don't rely on series designation alone — after an axle swap, the flange dimensions may differ from the original factory spec. Brand: UDS. Verify, then order.
