7 1/4 X 1 1/2 X 16 TUBE SHAFT

It has a 1.5-inch major diameter, 16 parallel splines, and a 7.25-inch length from the end of the spline to the weld point, designed to be welded into a 3-inch diameter, 0.083-inch wall steel tube. The slip spline allows the driveshaft to change length as the suspension moves, transmitting engine torque to the axles. This component is typically replaced when the splines wear out, causing driveline vibration, clunking, or excessive play, or if the shaft is bent or damaged from overload.
