N3-4-JK08 – End Yoke – 1350 Series – 1.250″ Splines Dia – 1.85″ Hub Dia

That clunk under acceleration that goes away when you grab the driveshaft and check for play — it's usually here, at the end yoke splines. The N3-4-JK08 end yoke is the correct 1350 series replacement. Count the splines on your output shaft before ordering. Don't guess by series alone.

N3-4-Jk08 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 N3-4-JK08 end yoke specs: 1.250" x 24 spline | 1.85" hub dia | 3.100"" CJ-to-end | 1.500" bore. FITS JEEP WRANGLER JK DANA 30 AND DANA 44 FRONT END. 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 N3-4-JK08 end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
