A: To remove and install the driveshaft, start by raising the rear of the vehicle and supporting it securely. Mark the relationship of the driveshaft to the companion flange on the rear axle pinion. Disconnect the rear Universal Joint by removing the nuts from the U-bolts or strap retaining bolts, or by removing the flange bolts. Lower the rear end of the driveshaft and withdraw the complete shaft assembly to the rear. During removal, the front splined sliding sleeve section will be drawn off the transmission output shaft, potentially causing a small amount of lubricant loss in vehicles with a manual transmission. When installing, align the shaft to flange mating marks and be careful not to damage the transmission extension oil seal with the sliding joint splines. Finally, check the transmission oil level once installation is complete.
