3-2-909 Flange Yoke 1480 series, 8×0.386 Holes on 6.125 BC, 5.312 M pilot

When a 1480 series flange yoke fails, the symptoms show up fast: driveline clunk under acceleration, vibration that doesn't go away with speed changes, or visible play at the diff flange. The 3-2-909 flange yoke is the spec-correct replacement — correct bolt circle, correct pilot, correct series. Dimension confirmation before ordering is still the right call.

3-2-909 Flange Yoke — 1480 Series Specifications & Fitment

The 1480 series covers heavy commercial Class 3-4 trucks and Dana heavy applications. The 3-2-909 flange yoke specs: 6.125 bolt circle | 5.312 pilot | 8x0.386 bolt holes | 1.938" CJ-to-flat | 6.875" swing dia. 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 3-2-909 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.
