90-4-311-1 – End Yoke – SPL90 Series – 2.024″ Splines Dia – 39 Spline

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 90-4-311-1 end yoke is the correct SPL90 series replacement. Count the splines on your output shaft before ordering. Don't guess by series alone.

90-4-311-1 End Yoke — Spline Specs & SPL90 Series Fitment

The 90-4-311-1 end yoke specs: 2.024 x 39 spline | 3.000"" hub dia | 4.625" CJ-to-end | 2.312 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 90-4-311-1 end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
