2-2-479 Flange Yoke 1310 series , 4x 0.438 Holes on 3.750 Bolt Circle Diameter , 2.750M pilot

The 2-2-479 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 2-2-479 flange yoke is the correct replacement.

2-2-479 Flange Yoke — 1310 Series Specifications & Fitment

The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The 2-2-479 flange yoke specs: 3.750 bolt circle | 2.750 pilot | 4x0.438 bolt holes | 1.375" 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 2-2-479 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.
