Buying a used Dodge Cummins requires a thorough inspection. These trucks are often worked hard, so diligence pays off.

1. Engine:

   • Cold Start: Listen for excessive cranking, knocking, or smoke.
   • Smoke: White smoke (coolant, unburnt fuel), blue smoke (oil), black smoke (excess fuel, often from modifications) – evaluate based on engine generation and modifications.
   • Blow-by: Remove the oil fill cap while the engine is running. Excessive pressure/smoke coming out indicates worn piston rings.
   • Leaks: Check for oil, coolant, or fuel leaks around the engine, transmission, and differentials.
   • Service Records: Ask for detailed maintenance history, especially oil changes, fuel filter replacements, and any major repairs.

2. Transmission:

   • Automatic: Test all gears, including reverse. Look for slipping, harsh shifts, or delayed engagement. Check fluid condition (should be reddish, not dark or burnt-smelling).
   • Manual: Test clutch engagement (should be smooth, not slipping). Listen for grinding noises during shifts.

3. Chassis & Suspension:

   • Rust: Critically inspect the frame, cab corners, rocker panels, wheel wells, and bed for rust, especially in regions that use road salt.
   • Suspension Components: Check for worn ball joints, tie rods, shocks, and bushings. Listen for clunks or squeaks over bumps.
   • Tires: Even wear indicates good alignment. Check tread depth.

4. Drivetrain:

   • 4×4: Engage 4-wheel drive (high and low) and test it. Listen for unusual noises from the transfer case or differentials.
   • Driveshafts/U-joints: Check for play or clunking.

5. Electronics & Interior:

   • Gauges: Ensure all dashboard gauges (oil pressure, temp, voltage, fuel) are working correctly.
   • Warning Lights: No check engine light, ABS light, or other critical warning lights should be illuminated.
   • HVAC/Power Accessories: Test the air conditioning, heater, power windows, locks, and radio.

6. Mileage vs. Maintenance: High mileage isn’t always a deal-breaker for a Cummins if it has been meticulously maintained. A lower mileage truck with poor maintenance can be a bigger headache.
