When fitting the P211229X, verify the companion flange bolt circle is 3.5" and the pilot bore is 2.0". The type F pilot registers on the companion flange face — confirm the pilot OD seats without interference. The socket OD of 1.394" is noted as a service dimension; inspect the ball socket for wear if reassembling from field service.

The 1310 series is the most common automotive and light truck driveshaft U-joint series in North America. The P211229X CV flange yoke serves applications where a constant-velocity joint is required at the transmission or transfer case output, such as lifted vehicle applications or high-operating-angle installations. The 2.0" pilot and 3.5" bolt circle are the primary companion flange matching dimensions.

The P211229X does not include a lube fitting. The 3.5" bolt circle is smaller than the 4.25" used on the P211913X (1330 series) — do not interchange these flanges. Verify both the bolt circle (3.5") and the pilot diameter (2.0") against the companion flange before ordering.
