1202-196 – Flange Yokes – 1251 Series – Bolt Circle Dia 3.550″ – Bolt Hole Dia 0.425

When a 1251 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 1202-196 flange yoke is the spec-correct replacement — correct bolt circle, correct pilot, correct series. Dimension confirmation before ordering is still the right call.

1202-196 Flange Yoke — 1251 Series Specifications & Fitment

The 1202-196 flange yoke specs: 3.550 bolt circle | 1.968-M pilot | 4x0.425 bolt holes | 1.625" 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 1202-196 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.
