2003 — 2008
5.7L HEMI V8 (345 cu in)
Petrol
While the engine is cold, listen closely for a rhythmic ticking sound near the wheel wells; in Hemis of this vintage, it is common to consider that the exhaust manifold bolts may have snapped or warped over time.
During a steady cruise, pay attention to any shuddering or hunting between gears; you might eventually find that the 545RFE transmission requires a specialized fluid service or solenoid pack update to maintain its smoothness.
Steer the truck over speed bumps or uneven driveways and listen for clunks; given the weight of the 5.7L engine, it's frequent for owners to eventually budget for a refresh of the front ball joints and tie rod ends.
Observe the dashboard for any significant cracking or movement; in the New Zealand climate, the plastics used in this generation are known to become brittle, and you may want to plan for a dash-mat or specialized plastic repair.
Major service interval including the replacement of all 16 spark plugs and a thorough inspection of the cooling system components.
Consider a comprehensive transmission and differential fluid exchange to protect the heavy-duty driveline components.
Potential for a full front-end suspension evaluation, as rubber bushings and dampeners often reach the end of their optimal service life here.
Check the condition of the timing chain tensioners and the water pump, which are parts that may invite preventative replacement in high-mileage trucks.
Verify the service history specifically for the 16-plug ignition system refresh.
Inspect the rear wheel arches and cab corners for any early signs of paint bubbling or oxidation.
Ensure the 4WD transfer case engages '4-Hi' and '4-Lo' smoothly without excessive mechanical protest.
Check the condition of the brake rotors, as these heavy trucks can be demanding on their braking hardware.
Confirm that the MDS (Multi-Displacement System), if equipped, transitions between 4 and 8 cylinders without significant vibration.
Estimated repair costs if issues arise
Depending on the car's history, you might eventually need to budget for a complete ignition refresh. Because the Hemi uses two plugs per cylinder, the labor and parts count is higher than a standard V8.
If a cold-start tick is present, future budget planning should account for machining the manifolds and replacing the bolts with high-grade fasteners to prevent future leaks.
In cars of this age, it is common to consider a proactive replacement of ball joints and control arm bushings to ensure the truck remains stable and safe on NZ roads.
