1-2186

2C ALL DRILLED U-JOINT

This is a Neapco 1-2186 universal joint, a key component in a truck’s driveline that transmits torque and rotation between the driveshaft and the axle. This specific style uses a wing-bearing design where all four bearing caps are low-wing drilled (LWD) and bolt directly to the yokes, making it common in medium and heavy-duty truck applications. The grease fitting in the end cap allows for regular lubrication, which is essential for extending service life under high-load conditions. You would typically replace this u-joint when you notice driveline vibrations, clunking sounds, or visible wear like rust or play in the bearings, often during a clutch job or driveline overhaul.
