Description And Operation: Driveshaft
The driveshaft is a 2-piece shaft which transfers the rotational torque from the power transfer unit (PTU) to the rear drive axle. The driveshaft uses constant velocity (CV) joints, U-joints and a center support for consistent operation through varying lengths and angles.
The driveshaft contains:
- spot welded balance weights.
- a front CV joint at the PTU.
- a center support bearing assembly with a ground strap.
- staked and snap ring type U-joints.
- U-joint cap straps for the center U-joint.
- square flanged rear U-joint.
