While driving at highway speeds, pay close attention to the transmission's shift points; it is common for the 46RE automatic units to benefit from periodic band adjustments or eventual refurbishing if gear hunting occurs.
Check this by removing the air cleaner and peering down the throttle body with a torch; if you notice oil pooling at the bottom, the intake plenum gasket might be a component to consider for replacement to ensure optimal engine performance.
While navigating a bumpy road, feel for any 'wandering' or excessive play in the steering wheel, as the steering gear boxes and track bar bushings on these trucks are parts that owners often choose to refresh to maintain a precise feel.
Inspect the dashboard under direct light for any signs of brittleness or cracking; in the New Zealand sun, these plastic panels can age, and you might eventually decide to budget for a dash cap or a replacement cover.
Consider a comprehensive cooling system flush and an inspection of the water pump and thermostat to ensure reliable long-distance towing.
This is a great time to check the timing chain slack and consider replacing the oxygen sensors to maintain fuel efficiency on the 5.9L Magnum.
Depending on usage, you might look at refreshing the universal joints (U-joints) and checking the differential seals for any signs of seepage.
At this stage of its life, many owners plan for a thorough suspension overhaul, including ball joints and shocks, to keep the ride quality comfortable.
Verify the condition and colour of the transmission fluid, as regular changes are key to the longevity of the Chrysler 4-speed units.
Check the condition of the vacuum lines under the bonnet, as these can become brittle and affect the cruise control or HVAC vent operation.
Inspect the rear wheel arches and cab corners for any signs of surface oxidation that might need a quick touch-up.
Ensure the transfer case fluid has been serviced recently if the vehicle is a 4WD model, to keep the engagement smooth.
Test the heater core's performance to ensure there are no sweet smells inside the cabin, which can occasionally suggest a slow leak.
Estimated repair costs if issues arise
If the transmission begins to show signs of slipping or delayed engagement in the future, you might eventually need to budget for a professional rebuild to restore factory-smooth shifting.
Depending on the car's history, you might eventually need to budget for the 'Hughes Plate' or a similar plenum repair kit to address oil consumption and prevent 'pinging' under load.
To ensure the truck tracks straight on NZ's winding roads, future budget planning for a new track bar, tie rod ends, and a steering stabilizer is a common consideration for 2nd Gen owners.
In trucks of this vintage, the fuel pump (located inside the tank) can eventually lose pressure; replacing the entire assembly is a standard piece of preventative maintenance.
