68036718AB – Flange Yokes – 1350 Series – Bolt Circle Dia 3.950″ – Bolt Hole Dia 0.430

The 68036718AB 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 68036718AB flange yoke is the correct replacement.

68036718Ab Flange Yoke — 1350 Series Specifications & Fitment

The 1350 series covers 3/4-ton trucks — F-250, Ram 2500, Dana 44/60 axles, performance 4x4. The 68036718AB flange yoke specs: 3.950 bolt circle | N/A pilot | 4x0.430 bolt holes | 2.375" 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 68036718AB 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.
