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. Locking differential, drain fluid and refill at first engine oil change. At subsequent oil changes, inspect fluid level and add fluid as needed. If driving in dusty areas or towing a trailer, drain fluid and refill every 25 000 km (15,000 miles). 3500 HD models drain and refill at 30,000 miles. More frequent lubrication may be required for heavy-duty or off-road use.
