2017 Ford Transit 2.0L Diesel · BL11 MMM

A pattern of recurring tyre wear and critical braking component failures defines the mechanical profile of this Ford Transit, culminating in a dangerous failure during the April 2026 testing period. While the most recent test on 28 April 2026 resulted in a pass with no defects recorded, this follows a significant failure just four days prior involving a seriously weakened rear brake disc and the fitting of mismatched tyre sizes on the offside rear axle. The history shows a recurring theme of tyre degradation and suspension component wear, specifically regarding nearside front lower suspension arm ball joint dust covers which were flagged in both 2024 and 2025, suggesting a need for close monitoring of steering and suspension integrity. The vehicle has covered 110,927 miles over approximately nine years, representing an average annual accumulation of roughly 12,325 miles. For a commercial vehicle like a Transit, this mileage is relatively high compared to standard domestic car usage, which typically correlates with increased wear on heavy-duty consumables. This level of usage places consistent stress on the drivetrain, particularly the constant velocity boots which were recorded as split on both nearside and offside front outer drive shafts in early 2022. The mileage suggests the vehicle has been in regular operation, which necessitates a thorough inspection of all rubber components and grease-retaining boots to ensure they have not been compromised by high-frequency movement or heat. Prospective buyers should pay particular attention to the braking system and steering assembly during a test drive. Given the recent dangerous failure regarding a weakened rear brake disc, it is essential to check for any pedal judder, uneven braking pull, or unusual grinding noises when applying the brakes. The history of deteriorated suspension ball joint dust covers means the vehicle should be tested for any knocking or clunking sounds when traversing uneven surfaces or turning the steering wheel at low speeds, as these symptoms can indicate play in the suspension linkages. Furthermore, the repeated advisories regarding tyres being worn close to the legal limit or worn on the edges suggest a need to inspect the current wheel alignment and camber settings. During the test drive, listen for any rhythmic humming or vibration that could indicate uneven tyre wear or issues with the wheel bearings. Because the vehicle has previously required intervention for split CV boots, a visual inspection of the drive shafts for any signs of grease leakage or torn rubber boots is also advised to prevent future drivetrain failures.
