Transmission: Check transmission oil level dip- stick. Oil level is checked with the engine running at idle speed, transmission in neutral and oil warm (160 to 190 degrees F [71 to 88 degrees C]). Oil should be at FULL line on dipstick. Drive Shafts: Visually check the connecting capscrews and drive shafts for damage. Examine the parking brake disc and brake pack. Check the function of the brake. Axles: Visually check all attaching bolts. Check the differentials and hub drives for lubricant levels. Visually check the steering cylinders and tie rods for damage. Check to be sure the torque on all wheel nuts is 450 to 500 1b-ft (610 to 678 N l m). Visually check tires for damage, and verify tire pressure. Tire pressure should be 90 psi (620 kPa).
