Observe the transmission shifting. During a gentle acceleration, pay attention to the gear changes; a slight delay or 'flare' in the A750F transmission can sometimes indicate that a fluid flush or solenoid check may be needed as the vehicle ages.
Operate the AHC (Active Height Control) system. Cycle through the ride height settings while stationary to ensure the suspension lifts and lowers smoothly; if it remains stuck, it is worth investigating whether the hydraulic fluid or pump requires attention.
Check the underside for dry-rotted rubber bushings. When driving over small bumps, listen for clunks or knocks from the front suspension, as the heavy weight of the LX570 can cause control arm bushings to show signs of wear over time.
Test the electrical folding mirrors and seat memory functions. These systems are robust, but it is common for the grease in the mirror motors to harden in older vehicles, so ensure they operate without hesitation or abnormal noises.
Usually the time to evaluate the condition of the radiator and coolant hoses to prevent cooling system fatigue.
A common point to check the starter motor and alternator brushes, as these components work hard to support the vehicle's luxury electrical features.
The period where original suspension components, specifically the AHC spheres, may reach the end of their design lifespan and require potential refurbishment.
Prioritize a timing belt replacement every 150,000km as recommended for the 2UZ-FE engine.
Change the transmission fluid periodically, as this helps maintain smooth shifting for the long haul.
Keep the AHC hydraulic fluid clean to ensure the suspension pump operates efficiently for years to come.
Regularly inspect the underbody for rust, especially if the vehicle has been exposed to coastal or winter road conditions.
Ensure all grease points on the driveshafts are topped up during your regular oil service intervals.
Estimated repair costs if issues arise
Since this is an interference engine, you should always treat this as a top priority for future budget planning. Replacing the belt, tensioner, and water pump ensures the 2UZ-FE engine keeps running reliably for many more kilometres.
If you notice the ride feels firmer than expected or the suspension is slow to adjust, you might eventually need to budget for replacing the hydraulic accumulators, which provide the 'cloud-like' comfort the LX is famous for.
Because the starter motor is located in the 'valley' of the V8 engine, it is a labor-intensive job to reach. It is wise to consider this as a potential future maintenance item if you notice any starting hesitation.
