The 5-7438XU is a combination joint bridging the standard 1330 (1.063" cap) to the 1330F Ford B-cap (1.125" cap). When installing, the 1.063" cap side mates with the 1330-series yoke, and the 1.125" cap side mates with the Ford B-cap yoke. Confirm the cap bore diameter in each yoke matches the respective cap before pressing. Both sides are 3.625" width, so yoke ear width is consistent across this joint. The greaseable design requires a lubrication interval using a standard grease fitting on the trunnion. The heavy-duty double-seal cap configuration retains grease longer under high-vibration and contamination conditions compared to single-seal caps. This combination joint is specified for Ford applications where the factory installed a B-cap yoke at one end of the driveshaft and a standard 1330 yoke at the other — do not substitute a single-series joint in this application.
