LubricateSteering and Suspension
Lubricate the front suspension (or every 12 months, whichever occurs first). Lubricate ball joints, kingpin bushings, steering linkage, transmission shift linkage, transfer case shift linkage, parking brake cable guides, rear driveline center splines, front axle propshaft splines and brake pedal springs. Ball joints and kingpin bushings should not be lubricated unless their temperature is -12 degrees C (10 degrees F) or higher or they could be damaged.
Inspect
Fluid - Differential
Inspect front/rear axle fluid level and add fluid as needed. Inspect constant velocity joints and axle seals for leaking. If driving in dusty areas or towing a trailer, drain fluid and refill every 25 000 km (15,000 miles). 3500 HD models with applications requiring extreme overload/trailer towing conditions and high-speed (above 45 mph or 70 km/h) conditions for extended periods of time must have the drive axle fluid changed every (3,000 miles) 5 000 km.
Replace
Oil Filter, Engine
Or every 3 months.

Only vehicles under 8,600 lbs. GVWR. Manual transmission fluid does not require change.
Engine Oil
Or every 3 months.
Air Filter Element
Dusty conditions may require more frequent filter replacement. Extreme dust and dirt operating conditions (off-road), may require the air filter to be checked as often as every 300 miles (483 km) and replaced as necessary.
