2009 Ford Focus 1.6L Diesel · TH51 COS

Chronic suspension wear and persistent corrosion define the mechanical history of this vehicle, with a recurring pattern of defects affecting the chassis and linkages. Rear coil spring corrosion has been a consistent advisory since 2022, remaining unresolved in the latest pass on 2025-12-02. The vehicle has also experienced multiple major failures involving the front lower suspension arm ball joints, trailing arm bushes, and anti-roll bar linkages over the last two testing cycles, indicating a trend of accelerating wear in the steering and suspension geometry. The recorded mileage of 130,369 miles over approximately 17 years represents an average annual usage of roughly 7,669 miles. This is typical for a vehicle of this age, suggesting a standard rate of wear on the drivetrain and chassis. The consistent annual testing interval confirms the vehicle has remained in active service, though the mileage accumulation is evident in the frequent requirement for replacement of suspension consumables and the long-term degradation of structural components like the rear springs. Prospective buyers should focus on the integrity of the suspension system during a physical inspection and test drive. Listen for knocks, rattles, or clunking sounds when driving over speed bumps or uneven surfaces, which may indicate that the previously flagged drop links or corroded rear springs have further deteriorated. The history of worn trailing arm bushes suggests the vehicle should be checked for any instability or steering wander during deceleration and cornering. Further attention is required for the non-excessive oil leak noted in 2024 and the previous reports of corrosion on the rear brake hose ferrules. A visual inspection of the engine bay and underbody is necessary to determine if the oil leak has progressed. Additionally, the latest advisories regarding worn rear tyres and a deteriorated offside front drop link boot should be treated as immediate maintenance requirements to ensure the vehicle remains roadworthy.
