REMOVAL & INSTALLATION
In order to remove the front and rear driveshafts, unscrew the holding nuts from the universal joint's U-bolts, remove the U-bolts and slide the shaft forward or backward toward the slip joint. The shaft can then be removed from the end yokes and removed from under the vehicle.
Each shaft is equipped with a splined slip joint at one end to allow for variations in length caused by vehicle spring action. 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. This is necessary in order to avoid vibration in the drive train. Tighten the U-bolt nuts to 15 ft. lbs. (20 Nm).
