2021 Ford Transit Custom 300LEADER Eblue 2.0L Diesel · YR71 FDV

The most recent MOT test on the 2021 Ford Transit Custom 300LEADER EBLUE occurred on 2025-11-05, where it failed due to critical issues with the near-side and offside front constant velocity (CV) joints, specifically the offside CV boot being split or insecure, allowing dirt ingress—a major failure category. This failure follows a prior MOT on the same date where only minor deterioration of the offside CV boot was noted, indicating a progression in the condition of that component. The vehicle’s MOT history reveals a pattern of recurring defects, particularly with the CV joints and front tyre wear, suggesting ongoing mechanical stress or inadequate maintenance. While the 2024 MOT results were clean, the subsequent failures highlight a concerning trend of component degradation, warranting immediate attention to prevent further damage or safety risks. The recorded mileage of 79,414 miles for a vehicle aged five years represents a notably high annual usage rate of approximately 15,883 miles per annum, which is unusually aggressive for its class. Such mileage accumulation typically accelerates wear on critical systems like the drivetrain, suspension, brakes, and tyres, as evidenced by the CV joint failures and severe tyre edge wear observed in the MOT records. The absence of significant mileage gaps implies continuous operational use, which can exacerbate issues such as fluid degradation, lubrication loss, and structural fatigue in suspension components. Given the CV joint failures, the vehicle may have experienced excessive lateral movement or misalignment, leading to premature boot deterioration and eventual joint failure. This pattern underscores the need for a thorough inspection of the entire drivetrain, including the other CV joints, universal joints, and drive shafts, to mitigate the risk of further transmission-related failures. For prospective buyers, the most pressing immediate concerns stem from the critical CV joint failures, which require urgent replacement to prevent drivetrain damage, excessive wear on the differential and transmission, or even catastrophic failure during operation. Inspect the CV boots and joints visually for leaks, cracks, or excessive play, and listen for unusual noises—such as clunking or grinding—when accelerating or turning, especially at low speeds. The offside front tyre advisories, indicating edge wear and proximity to the legal limit, suggest uneven camber or toe-in, which could be linked to suspension or steering system issues. Test the vehicle for suspension clunks or binding in the front axles, and check for uneven tyre wear patterns that may indicate misalignment or suspension component wear. Additionally, verify the condition of the front windscreens and wipers, as the MOT failures indicate ineffective clearing, which could impair visibility and increase accident risk. Beyond the immediate defects, the vehicle’s high mileage and recurring MOT issues necessitate a comprehensive mechanical inspection. Focus on the rear CV joints, differential lubrication, and transmission fluid condition, as these are likely to have suffered from the aggressive usage. Check for signs of fluid leaks around the drivetrain, particularly under the vehicle, and ensure the transmission fluid is at the correct level and free of contaminants. Inspect the suspension components, including coil springs, shock absorbers, and suspension bushes, for signs of wear or corrosion, as the CV joint failures may have contributed to suspension stress. Pay particular attention to the brake system, including disc thickness, caliper binding, and brake fluid condition, given the potential for standing corrosion or fluid degradation over time. Finally, given the vehicle’s age and usage, consider a thorough inspection of the exhaust system for emissions compliance and structural integrity, as well as a check of the 12V battery and starter motor for signs of failure, which are common in high-mileage vehicles. If possible, obtain a pre-purchase inspection from a qualified mechanic to confirm the severity of the CV joint failures and assess the overall mechanical condition.
