While driving at highway speeds, listen for any drivetrain vibrations; due to the age of these vehicles, it is common to consider checking the state of the universal joints and the carrier bearing on the tailshaft.
Check this by idling for an extended period after a spirited drive, keeping an eye on the temperature gauge to ensure the cooling system is managing the heat, as the TB45E is known to be quite efficient but also heat-sensitive in heavier applications.
While stationary, shift through the transfer case gears including 4WD-High and 4WD-Low; it is wise to observe if the engagement is smooth, as sticky linkages can be a sign that the 4WD system hasn't been exercised regularly.
Inspect the underside for signs of corrosion or persistent oil leaks around the rear main seal, as in vehicles of this vintage, minor weeping is sometimes observed and worth noting for your long-term maintenance plan.
Usually marks the point where cooling system hoses and the radiator may benefit from a refresh to ensure ongoing reliability.
A common interval for considering a full suspension bush overhaul to maintain the Patrol's characteristic ride comfort.
Typically when original ignition components or auxiliary belt tensioners may reach the end of their service life.
Prioritize regular oil and filter changes every 5,000km to keep the 4.5L straight-six running smoothly.
Keep a close eye on your coolant levels and quality; it is the lifeblood of the TB45E engine.
Regularly grease your driveshaft universal joints to keep the driveline operating quietly.
Check your air filter frequently, especially if the vehicle has been used for dusty off-road adventures.
Ensure your brake fluid is flushed every two years to maintain optimal stopping power for such a heavy vehicle.
Estimated repair costs if issues arise
Given the age of the vehicle, you might eventually need to budget for a cooling refresh to prevent overheating issues. This typically involves replacing the radiator, water pump, and aging rubber hoses.
If the steering feels a bit vague or the ride becomes less composed, you might consider budgeting for a full set of polyurethane or rubber suspension bushings to restore that factory feeling.
It is quite common on the TB45E for the exhaust manifold studs to loosen or break over time. If you hear a ticking sound under load, this is the first place to look for repair.
