3-4-2231-1 End Yoke – Splined Bore 1350 Series, Strap Style, 1.500×10 Spline, 2.253 Hub

The 3-4-2231-1 end yoke connects the driveshaft end to the axle or transfer case output shaft via a splined bore. Spline count and diameter are the critical dimensions — a mismatch here means the yoke either won't engage the shaft or will engage loosely and spin out under load. The 3-4-2231-1 end yoke is machined to one specific spline specification for 1350 series applications.

3-4-2231-1 End Yoke — Spline Specs & 1350 Series Fitment

The 1350 series covers 3/4-ton trucks — F-250, Ram 2500, Dana 44/60 axles, performance 4x4. The 3-4-2231-1 end yoke specs: 1.500" x 10 spline | 2.253" hub dia | 3.905" CJ-to-end | 2.185 bore. Hub diameter is the outer dimension that clears the axle housing or T-case bore. CJ-to-end determines how the u-joint positions relative to the flange or seal surface. Count the splines on your output shaft — don't go by the vehicle model alone. Axle swaps and rebuilds can change the spline count from the original. The 3-4-2231-1 end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
