Full Description
3-2-489 UDS 1480 Flange Yoke
The 3-2-489 is a 1480 series flange yoke manufactured by UDS. It bolts to a companion flange on the transmission, transfer case, or differential output using a 4-bolt pattern on a 4.750-inch bolt circle. The 3.750-inch pilot diameter registers the yoke concentrically against the companion flange to minimize runout.
The 4 bolt holes are 0.500-inch diameter on the 4.750-inch bolt circle. The center-U-joint-to-flange-face dimension is 1.500 inches. This 1480 series yoke accepts a 1480 U-joint in the yoke ears — the ear bore is machined specifically for the 1480 cap diameter. Application note: Rectangular Bolt Pattern 3.053 x 3.639". The 1480 series ranks above 1410 in torque capacity, with a 1.375-inch cap diameter, suited for heavy-duty commercial trucks and large SUVs.

Fitment & Installation Notes
Before ordering the 3-2-489, measure the bolt circle diameter and pilot diameter on the companion flange. The bolt circle (4.750") and pilot (3.750") must match exactly. A 1480 U-joint is required — do not install a different-series joint in these ears.
