4-0674
The Neapco 4-0674 is a heavy-duty universal joint for the 1610 half-round driveline series. It allows angular movement between driveshaft components, transmitting power while compensating for suspension flex. You typically replace it when you notice driveline vibration, clunking, or excessive play in the joint, which can lead to driveshaft failure. This U-joint is greaseable, with two zerk fittings in the cross for regular maintenance [neapcoparts.com](https://neapcoparts.com/4-0674-universal-joint/).
