5-4-7171-1 – End Yoke – 1610 Series – 1.790″ splines dia – 2.188″ Hub Dia”,

The 5-4-7171-1 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 5-4-7171-1 end yoke is machined to one specific spline specification for 1610 series applications.

5-4-7171-1 End Yoke — Spline Specs & 1610 Series Fitment

The 1610 series covers Class 5-7 commercial and heavy fleet. The 5-4-7171-1 end yoke specs: 1.790" x 34 spline | 2.188" hub dia | 4.125" CJ-to-end | 2.250" bore. COUNTERBORE .500". 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 5-4-7171-1 end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.
