1998 Isuzu Trooper 3.0L Diesel · SWC 253

The most recent MOT on 27 August 2026 was passed, the only comment being a general underside corrosion advisory. Over the last six years the vehicle has alternated between passes with a number of minor advisories and isolated failures – notably a fuel‑tank leak in 2023, lamp and wiper failures in 2025 and a front wheel‑bearing advisory in 2024. The pattern shows that significant faults have been rectified, but a suite of recurring wear items (anti‑roll‑bar bushings, front wheel bearing play and light oil mist from the front shocks) persists, indicating a maintenance trend that is currently stable but still requires attention to prevent deterioration. With 129,534 mi recorded on a 1998 model the average annual mileage is roughly 4,600 mi, well below the typical 10‑12 000 mi per year for a vehicle of this age. Such low utilisation usually points to periods of limited use or extended storage, which can be kinder to the power‑train but harsher on components that age with time rather than use. Prolonged standing can accelerate under‑body corrosion, cause battery sulphation, and allow rubber seals, hoses and tyres to dry out and crack, while the modest mileage means that wear on the engine, gearbox and drivetrain is likely to be light but may be masked by age‑related fatigue. A prospective buyer should give particular focus to the items that have appeared repeatedly in the MOT records. Inspect the front anti‑roll‑bar pins and bushes on both sides for any looseness, excessive play or cracked rubber; a worn bush will manifest as a clunk or vague knock when cornering or passing over bumps. The off‑side front wheel bearing, flagged for slight play, should be checked for a low‑frequency hum or grinding that grows with speed – any increase in noise may indicate bearing wear beyond the advisory threshold. Verify that the front wiper now clears the screen effectively and that both headlamp aims are correctly set, as mis‑aim can cause glare and reduce night‑time visibility. Although the fuel‑tank leak was recorded three years ago, a careful visual inspection under the vehicle for any fresh fuel odour or staining is prudent, and the fuel tank should be examined for rust or compromised seams, especially given the vehicle’s age and history of corrosion. Beyond the specific MOT items, the buyer must conduct age‑appropriate checks. Examine all tyres for sidewall cracking, dry rot and tread depth; even if the tread is adequate, tyres older than six years should be replaced regardless of mileage. Test the 12 V battery with a load tester, as long periods of inactivity can leave it unable to hold charge. Scrutinise the under‑carriage for any progression of the general corrosion advisory – look for rust on chassis rails, suspension mounting points and exhaust hangers, which can affect structural integrity. Confirm that coolant, brake fluid and gearbox oil have been changed within the recommended intervals (typically every two years for fluids in a vehicle of this vintage). Finally, on a test drive listen for any unusual vibrations, brake shudder or steering pull, and ensure the brakes feel firm and the steering is free of play, as these are early indicators of wear that may not yet have triggered an MOT failure.
