Oil Change Gasoline:
Typically every 3,000-5,000 miles or 6 months, depending on usage and oil type (refer to manual for exact recommendations).
Oil Change Diesel:
Typically every 7,500-15,000 miles or 12 months with synthetic oil and filter, but strongly dependent on operating conditions (heavy towing/idling can reduce interval).
Fuel Filter Diesel:
Recommended replacement every 15,000-30,000 miles for diesel trucks to prevent injection system damage.

Diesel Injection Pump:
Early 5.9L Cummins engines can experience issues with the injection pump (VE pump) if not properly maintained or if fuel quality is poor. The 2002 models typically feature the P7100 or early common rail system which are generally robust, but still require good fuel and filter maintenance.
Transmission Overdrive Clutches:
Automatic transmissions (47RE/48RE) can develop issues with overdrive clutch packs or solenoid failures, particularly with higher mileage or heavy use.
Front Suspension Components:
Heavy-duty trucks can experience wear in ball joints, tie rod ends, and steering linkages due to load and use. Regular inspection is crucial.
Cooling System Radiator:
Radiator leaks or core degradation can occur over time, especially in harsh environments or with improper coolant maintenance.
