Dana Spicer 5-423X or 5423X greaseable U-joint kit from the 1610 Series, half round style, with the grease zerk in the center of the cross. The zerk lets you pack fresh grease into the joint during routine driveline service. A universal joint carries driveshaft torque between shafts that are not in line, so power keeps flowing as the suspension moves and the angle changes. Because the joint works at an angle, a tired one shows up as driveline vibration and extra wear. A genuine Dana Spicer part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
