5.7L (Gen III) V8 - SS
Petrol
While accelerating at low speeds, listen carefully for any clunking or thumping from the rear end; the rear suspension bushes on these utes can show their age and may eventually require replacement.
Check this by idling the vehicle for a few minutes; monitor the temperature gauge closely to ensure the cooling system is performing optimally, as these V8s run warm and original radiator components often reach the end of their service life.
During your inspection, engage the transmission while stationary; check for any delayed engagement or harsh shifting, as the 4L60E automatic gearbox can be sensitive to fluid degradation over high mileage.
Inspect the cabin floor and the underside of the dash; look for signs of dampness or water ingress, as the door and windscreen seals on VZ models can harden over time, potentially needing attention to keep the interior dry.
Consider a full cooling system flush and replacement of the water pump if it hasn't been done.
Monitor the health of the alternator and starter motor, as these often reach the end of their design life around this point.
Time to inspect suspension struts and shock absorbers to ensure the ute maintains its ride comfort and handling safety.
Regularly check your engine oil levels every few weeks; keeping the Gen III V8 topped up is key to its longevity.
Ensure your coolant is replaced every 2-3 years to protect the alloy engine internals from corrosion.
Keep an eye on the transmission fluid color and smell; clear, red fluid is what you want to see.
Inspect the tailshaft center bearing periodically for any signs of rubber fatigue or excessive vibration.
Don't ignore squeaks in the belt drive; replacing the serpentine belt and tensioner is a great way to prevent roadside surprises.
Estimated repair costs if issues arise
If this component needs attention in the future, it is a labor-intensive job because the transmission usually needs to be removed to access the seal. It is a common area to watch for seepage in high-mileage Gen III engines.
Depending on the car's history, you might eventually need to budget for a refresh of the 4L60E transmission if you notice slipping or sluggish gear changes as the internal clutches wear down.
In cars of this age, it's common to consider a full replacement of the rubber suspension bushes to restore the ute's handling and eliminate rattles. This usually involves replacing components in the rear and front ends.
