2015 Toyota Hilux 3.0L Diesel · FD64 JBU

The defining mechanical concern for this Hilux is a clear pattern of chassis and braking-related deterioration rather than a clean MOT profile. Across five recorded test events since 2019 the vehicle has accumulated one dangerous stop lamp failure, a fractured rear leaf spring recorded as a major defect, two further fail events covering lighting and wiper functionality, and persistent advisories for slight corrosion on most brake pipes which have appeared on three consecutive tests up to the most recent pass on 24 November 2023. The 2022 fail was particularly significant because the nearside rear leaf spring fracture was not an isolated advisory but a structural suspension item that failed outright, and the dangerous stop lamp defect recorded in December 2020 represents the highest risk category a tester can apply. Despite this, the 2023 pass without major or dangerous defects suggests some rectification has occurred, yet the recurring brake pipe corrosion and the older exhaust mounting advisory indicate that the underlying corrosion picture has been carried forward rather than resolved. Mileage accumulation at 177,403 miles on an eleven-year-old vehicle equates to roughly 16,100 miles per year on average, which is considerably above typical private use and points to prolonged working or commercial operation. There are gaps in the recorded testing timeline, with the December 2021 pass recorded on the same day as a failure, indicating the vehicle was re-presented after remedial work, and no tests logged between 2019 and the end of 2020. The mileage jump implied between the 2023 test and earlier records is consistent with sustained heavy use, which mechanically raises the probability of wear on suspension bushes, dampers, prop shaft components, clutch and driveline bearings, and the diesel engine ancillaries. A usage profile of this kind means that consumables such as brake pads, discs and tyres will have been replaced multiple times, but also that fatigue-related failures on the leaf spring assembly, exhaust mountings, and underbody fixings are more likely to recur. Any prospective buyer should physically inspect the brake pipework along the full chassis length, paying particular attention to the fuel and brake line runs along the inner wings and under the cab, looking for live rust, scaling, or any sign of recent pipe replacement that may have been done merely to clear the advisory without addressing the surrounding corroded unions. The rear leaf spring assembly warrants close examination on a ramp or over a pit, checking for cracks at the spring eyes, any shackle wear, and whether the second leaf or overload spring has been replaced, since a fractured main leaf in 2022 indicates the original component reached its fatigue life and the replacement may itself be approaching similar mileage. On a test drive, listen for clonks or squeaks from the rear axle over speed humps and uneven surfaces, and feel for any rear-end instability or harsh rebound which would suggest worn bushes in the spring eyes or dampers that have lost damping efficiency. The exhaust mounting advisory from the 2023 test should also be confirmed as rectified, with a check for any exhaust blow at the joints or movement when rocked by hand. The earlier failures on stop lamps, position lamps, the horn, and both windscreen wipers collectively point to age-related electrical deterioration, so all exterior lighting, the horn, and wiper operation should be cycled during inspection, and any evidence of water ingress into the front lighting clusters noted. Finally, given the working-duty mileage, a thorough underbody inspection for oil leaks from the engine sump, transfer box and rear differential is advisable, alongside a check of the clutch for any slip under load and the steering for play that could indicate wear on the power steering rack or front suspension linkages.
