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.
