2005 Mitsubishi Shogun 3.2L Diesel · WN55 NHZ

The latest MOT test conducted on 5 August 2026 resulted in a PASS, although the vehicle had also failed earlier on the same date prior to remedial work being undertaken. The recent test history reveals a deteriorating structural and mechanical trend rather than a stable condition. Across the 2024 to 2026 period, multiple Major defects have been recorded relating to corroded suspension mounting areas, a corroded brake master cylinder and servo mounting, an excessively worn lower suspension arm ball joint, a missing steering rack gaiter, a major exhaust leak, and a dangerous tyre tread depth breach. While the vehicle has consistently passed its tests after repairs, the recurring advisories regarding nearside front wheel bearing play and general underside corrosion, now recorded at every test for three consecutive years, indicate an ongoing and progressive deterioration that should not be overlooked. The recorded mileage of 107,004 miles across approximately 21 years equates to an annual average of around 5,095 miles, which is notably low for a vehicle of this age. Such limited usage typically suggests either predominantly short journeys or extended periods of standing, both of which carry their own mechanical consequences. Short trips prevent the engine and exhaust system from reaching full operating temperature, leading to moisture accumulation in the engine oil, accelerated internal corrosion, and premature degradation of the exhaust system and catalytic converter. Extended standing periods, on the other hand, promote brake disc corrosion, caliper binding due to seized pistons, deterioration of rubber seals and gaiters, and 12V battery sulphation. The underbody corrosion repeatedly flagged in MOT records is consistent with a vehicle that has seen significant standing time or winter road salt exposure without regular use to keep moisture and contaminants from settling into structural and suspension components. Given the recurring advisories and defect patterns, a prospective buyer should carry out a thorough physical and dynamic inspection. The persistent nearside front wheel bearing play, noted at every test since at least 2023, warrants particular attention. On a test drive, listen for a humming or droning noise that rises and falls with road speed and may change when cornering, as this typically confirms bearing wear progression. The exhaust system has already suffered a major leak, and the underside is described as rusty including subframes; a careful examination on a ramp is essential to assess the severity of structural corrosion, paying particular attention to suspension mounting points, the brake servo and master cylinder area, and the integrity of subframe and chassis sections. Inspect the front lower suspension arms and ball joints for perished or split dust covers and any play when the wheel is rocked by hand, and check the steering gaiter for splits or absence, which would indicate renewed steering rack contamination. Brake discs should be examined for lipping, scoring, and surface corrosion, and calipers should be checked for smooth operation, as standing use commonly leads to seized slider pins. Tyres should be inspected for both legal tread depth and, given the vehicle's age, for sidewall cracking or perishing of the rubber compound, which can render even well-treaded tyres unsafe. Beyond the documented MOT issues, age-appropriate servicing items demand verification. Coolant, brake fluid, and automatic or transfer gearbox fluid all degrade with calendar age regardless of mileage, and records should be checked to confirm these have been renewed within the manufacturer's recommended intervals. The 12V battery should be load tested, as vehicles used sparingly are prone to chronic undercharging and premature battery failure. The headlamp lenses, noted as slightly defective with poor image on the most recent test, should be assessed for UV degradation and condensation, and the vehicle should be checked for any oil or coolant leaks that may have developed since standing. A compression test and inspection of the timing belt replacement history, which is critical on this Mitsubishi diesel platform at this age and mileage, would also be highly advisable. Finally, given the cumulative corrosion evidence, a professional pre-purchase inspection on a lift is strongly recommended to determine whether the vehicle remains structurally sound or whether rectification costs will be substantial.
