U-JOINT (CAT CT2D2978)

A worn U-joint can cause driveline vibration and eventual component failure. The U-joint, or universal joint, transmits rotational power through an angle while accommodating misalignment between connected shafts. Its plain mechanical function is to allow a drive shaft to flex as the suspension moves. A concrete generic failure consequence is that a seized U-joint can lead to a broken drive shaft or damaged transmission output. Keeping a U-joint in sound condition helps prevent unexpected downtime and costly repairs. This aftermarket replacement part references the CAT catalog number CT2D2978.
