Description And Operation: Driveshaft

The driveshaft has:

• a fully retained U-joint pinion flange for a positive engagement with the rear axle.
• a splined slip-yoke that permits the driveshaft to move forward and rearward on the transmission output shaft during drivetrain movement to maintain the required varying driveshaft length during normal vehicle operation.
• conventional U-joints that allow a smooth rotation of the driveshaft through the constantly varying angles the driveshaft encounters during jounce and rebound.

The driveshaft is a tubular shaft that transfers the rotational torque from the transmission to the rear drive axle. The tube can be aluminum or steel and the diameter of the tubes can vary, depending on the application. All driveshafts are balanced as assemblies. If the vehicle is to be undercoated, cover the driveshaft assembly to prevent overspray of any undercoating material.
