When pulling the driveshafts, it is prohibited to beat the yoke ears or to wedge in between yoke and the universal joint and thus avoid frakture and early failure. To check the rear driveshafts, standing on jackstands and block the front wheels, raise the rear of the vehicle securely. Shift to park release the parking brake apply the exact amount of pressure to put the transmission in Neutral and label at the flange of the driveshaft and the pinion. The rear universal joint bolts and retainers must be unscrewed; the use of a large screwdriver will help to turn the driveshaft. On the vehicles with two-part driveshaft release the center support bearing fasteners. Secure the bearing caps to the universal joint so they will not come off, then lower the rear of the driveshaft and slide the front out of the transmission or transfer case. It is necessary to cover the transmission or transfer case housing with a plastic bag and fix it with a rubber band in order not to lose and contaminate the fluid. As for installation, untie the plastic bag and clean the place for the drain and check on the oil seal. Bring the front of the driveshaft into position with the transmission or transfer case, position the center support bearing for two piece driveshafts and fasten securely. On the comes to optimize marks on the rear of driveshaft, withdraw tape from the bearing cap and prepares the clamp and bolts to be used for tightening with the recommended torque. On 4WD models for the front driveshaft, raise the front of the vehicle and safely secure it and, if provided, remove the differential carrier splash shield. Loosen but do not remove the clamp securing the boot in place to the transfer case output shaft, release the boot and take a marker and align it to the relationship between the driveshaft and the companion flange of the front differential before removing the bolts and clamps. The best approach is to push the driveshaft to come out of the rearwards of differential flange, tape the bearing caps , lower the driveshaft and pull out of the transfer case. Optional, to dispose of the clamp and boot, you will have to unboltnut and washer assembly from the driveshaft. To install it, firstly can slide the rear of the driveshaft into the splines of the transfer case output shaft then align the marks on the companion flange on the front end attaching it to the differential, remove the tape, then the clamps and bolts must be tightened to the recommended torque. Last is to push the boot over the transfer case output shaft, set it into the groove, use a small screwdriver to balance the pressure inside the boot and new clamp. Replace the front differential carrier splash shield only if the vehicle has one.
