5102-1582 – Flange Yokes – 1510 Series – Bolt Circle Dia 5.120″ – Cj To Flat 3.240

The 5102-1582 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 5102-1582 flange yoke is the correct replacement.

5102-1582 Flange Yoke — 1510 Series Specifications & Fitment

The 5102-1582 flange yoke specs: 5.120 bolt circle | 0.000 pilot | 8x0.472 bolt holes | 3.240" 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 5102-1582 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.
