3102-39 | 2-2-899-1 , 1310 Series Nissan / Subaru Pilot: 57mm male , 2.250 Inch

The 3102-39 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 3102-39 flange yoke is the correct replacement.

3102-39 Flange Yoke — 1310 Series Specifications & Fitment

The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The 3102-39 flange yoke specs: 2.750 bolt circle | 2.245 pilot | 4x0.315 bolt holes | 1.625" CJ-to-flat. Mostly used on Nissan. 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 3102-39 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.
