2013 Subaru Forester 2.0L Diesel · PX13 NDG

Chronic degradation of the suspension system and emerging corrosion define the current mechanical state of this vehicle. While it passed its most recent test on 25 March 2026, the record shows a worsening trend in chassis components, including a failure in February 2026 due to excessively worn front suspension arm ball joints and compromised dust covers. Current advisories persist regarding corrosion and worn pins or bushes on both rear upper suspension arms, as well as corrosion on the nearside front Macpherson strut mounting. The recorded mileage of 155,019 miles is consistent with the vehicle's thirteen-year age, averaging approximately 11,925 miles per year. This level of usage indicates a steady accumulation of wear on high-stress components, which is reflected in the recurring need for suspension and braking system attention. Such mileage typically coincides with the end of the natural service life for rubber bushings and ball joints, as evidenced by the recent failures and advisories. During a physical inspection and test drive, particular attention must be paid to the suspension geometry and stability. Listen for knocking or clunking sounds when traversing speed bumps or uneven road surfaces, which would indicate that the worn rear upper suspension arm bushes or the corroded Macpherson strut mounting have deteriorated further. Any vague steering response or unusual vibrations through the chassis should be scrutinized, as these can be symptoms of the ball joint wear that previously caused the vehicle to fail its MOT. The historical record indicates a recurring issue with brake disc pitting and scoring across all four corners, as noted in 2021 and 2022. A test drive should include several firm braking applications to check for pedal judder or steering wheel oscillation, which would suggest the discs remain scored or have warped. Additionally, the tyres should be inspected for the cracking and perishing noted in 2025 to ensure the rubber has been replaced and is not currently compromised.
