The driveshaft is a tubular construction designed as a one-section type, with both ends of the front 4WD driveshaft bolted to the respective transfer case and differential flanges, while a splined sleeve is incorporated midway. The rear driveshaft attaches to the rear axle pinion flange using a bolted flange, and its connection to the transmission or transfer case varies depending on the driveline package (2WD or 4WD). Care should be taken when replacing universal joints to maintain the finely balanced nature of the driveshaft, and it is recommended to seek professional assistance if unsure. When replacing the joints, marking each individual yoke is advised to preserve balance, and caution should be exercised to prevent dropping the assembly during servicing. On 2WD models, a splined yoke called a "slip yoke" or "sleeve yoke" is employed at the front, allowing the driveshaft to slide within the transmission. An oil seal prevents leakage and contamination. If leakage is observed at the front of the driveshaft, the oil seal should be replaced. On 4WD models, each driveshaft is attached to the transfer case by a flange yoke, and the companion flange can be removed to replace the companion seal(s). Proper maintenance involves keeping the driveshaft clean and free from undercoating or debris, ensuring the small balance weights are intact and securely attached, and reinstalling the driveshaft in the same position to maintain balance when removed. Problems with the driveshaft are typically indicated by noise or vibration while driving and a road test can help determine if the issue lies with the driveshaft or another vehicle component, prompting further inspection if necessary.

Look under the vehicle for grease fittings on the driveline components (4WD models). They are normally found on the driveshaft universal joints and slip yokes. For easier access under the vehicle, raise it with a jack and place jackstands under the frame. Before beginning, force a little grease out of the nozzle to remove any dirt from the end of the gun. Wipe the nozzle clean with a rag. With the grease gun and plenty of clean rags, crawl under the vehicle and begin lubricating the driveshaft universal joints. Pump grease into the universal joints until it can be seen coming out from the seals. Wipe the area around the grease fitting free of dirt, then squeeze the trigger on the grease gun to force grease into the component. Continue pumping grease into the fitting until it just oozes out of the bearing cup seals. If it escapes around the grease gun nozzle, the fitting is clogged or the nozzle is not completely seated on the fitting. Resecure the gun nozzle to the fitting and try again. If necessary, replace the fitting with a new one. Wipe the excess grease from the components and the grease fitting. Repeat the procedure for the remaining fittings. Lubricate the driveshaft slip yoke by pumping grease into the fitting until it can be seen coming out of the slip yoke seal. While you are under the vehicle, clean and lubricate the parking brake cable along with the cable guides and levers. This can be done by smearing some chassis grease onto the cable and its related parts with your fingers. Lubricate the contact points on the steering knuckle stop and adjustment bolt if equipped. Open the hood and smear a little chassis grease on the hood latch mechanism. Have an assistant pull the hood release lever from inside the vehicle as you lubricate the cable at the latch. Lubricate all the hinges (door, hood, etc.) with engine oil to keep them in proper working order. The key lock cylinders can be lubricated with spray-on graphite or silicone lubricant, which is available at auto parts stores. Lubricate the door weatherstripping with silicone spray. This will reduce chafing and retard wear.

To remove the driveshaft, start by loosening the wheel lug nuts and raising the vehicle, securing it on jack stands. Use a scribe, hammer, punch, or paint to make marks on the driveshaft flange yoke and the differential flange, ensuring they are in line with each other for proper reinstallation. Remove the bolts or nuts that secure the flange yoke to the differential, adjusting the driveshaft or wheels as needed for better access. Lower the rear of the driveshaft and slide the front out of the transmission for 2WD models. For 4WD models, separate the flange at the transfer case by removing the bolts and nuts. On 2WD models, wrap a plastic bag over the transmission extension housing and secure it with a rubber band to prevent fluid loss and contamination during driveshaft removal. For installation, remove the plastic bag from the transmission and clean the area. Carefully inspect the oil seal. Slide the front of the driveshaft into the transmission for 2WD models or bolt the flange yoke to the transfer case for 4WD models, tightening the fasteners finger-tight for 4WD models. Raise the rear of the driveshaft into position, ensuring that the marks on the flange yoke and differential are aligned. If necessary, turn the rear wheels to match the pinion flange and driveshaft. Finally, tighten all bolts and nuts to the specified torque, remove the jackstands, and lower the vehicle.
