3304-30 – End Yoke – 1.328″ Splines Dia – 30 Spline – 1.739″ Hub Dia

End yoke failures are usually easy to diagnose: cracked ears, worn splines, or corrosion at the cap bores. Whatever the cause, the 3304-30 end yoke is the direct replacement for 1330 series applications. Spline count and shaft diameter both have to match — verify yours before ordering.

3304-30 End Yoke — Spline Specs & 1330 Series Fitment

The 1330 series covers light-to-medium duty trucks and GM half-ton platforms. The 3304-30 end yoke specs: 1.328 x 30 spline | 1.739" hub dia | 2.600"" CJ-to-end | 1.19 bore. GM 8.875. 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 3304-30 end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
