2004 Subaru Legacy 2.5L Petrol · SL04 JWD

Corrosion of the integral body structure and rear subframe, alongside recurring suspension component wear, represents the primary mechanical risk for this vehicle. The most recent MOT test on 06 January 2022 recorded a pass, but it followed a failure involving a major exhaust leak and lighting defects. The documentation shows a persistent trend of advisories related to structural corrosion on the crossmember and subframe, which, while noted as not significantly reducing structural rigidity at the time of testing, indicates an ongoing degradation of the chassis. The vehicle has covered 123,324 miles over its 22-year lifespan, averaging approximately 5,606 miles per year. This is a low annual mileage rate for a vehicle of this age. While lower mileage can reduce wear on certain high-frequency components, the recorded history shows that even with this usage pattern, the vehicle has been subject to significant advisory notes regarding CV boot deterioration, brake component wear, and suspension bush degradation. The relatively low usage does not appear to have prevented the onset of structural corrosion or the wear of rubber components like gaiters and bushes. Prospective buyers should pay close attention to the underside of the vehicle during a physical inspection, specifically targeting the front crossmember and rear subframe mentioned in the 2022 records. Any signs of advancing surface rust or scaling should be evaluated. On a test drive, pay close attention to the suspension performance; the 2022 test flagged worn arm pins and bushes on the nearside rear, offside rear, and nearside front. You should listen for knocking, clunking, or thudding sounds when driving over uneven surfaces or speed bumps, which would indicate that these suspension linkages require replacement. Braking components and drivetrain integrity also require scrutiny based on the historical data. Previous tests have flagged worn, pitted, or scored brake discs and thinning brake pads, so the pedal feel should be checked for any pulsation or judder during braking. Furthermore, the history of damaged constant velocity (CV) joint gaiters and boots suggests that the drivetrain's protection against debris has been a recurring issue. During the test drive, turn the steering wheel fully to one side while moving slowly and listen for clicking or popping noises, which can indicate CV joint wear resulting from compromised boots.
