The front driveshaft has a single cardan universal joint at each end. A slip yoke is used to attach the shaft to the front axle yoke.
The rear driveshaft is one-piece with a single cardan universal joint at each end. A slip yoke is used to attach the shaft to the transfer case output yoke.
Some slip joints are marked with arrows at the spline and sleeve yoke. When installing, align the arrows. If the slip joint is not marked with arrows, align the yokes at the front and rear of the shaft in the same horizontal plane. Scribe alignment marks as necessary for correct installation in order to avoid vibration in the drive train.
REMOVAL & INSTALLATION
See Figures 1 and 2
- Raise and safely support the vehicle.
- Scribe alignment marks on the yokes at the transfer case, at the drive pinion gear shaft at each end of the driveshaft for installation reference.
- Remove the U-bolt strap bolts at the drive pinion gear shaft (axle) yoke.
- Disconnect the driveshaft at the transfer case and remove the driveshaft.
- Position the driveshaft with the yoke installation reference marks aligned at the transfer case and the drive pinion gear shaft yokes.
- With the driveshaft in the correct position, use new U-joint straps and bolts and tighten the bolts to 14 ft. lbs. (19 Nm).
