2004 Toyota Previa 2.4L Petrol · WN54 JGZ

The 2004 Toyota Previa presents a complex roadworthiness picture marked by a persistent pattern of recurring component failures rather than a clean driving record. The most recent MOT on 2022-08-17 returned a pass status, yet it carried five distinct advisories spanning brake systems, suspension linkages, lighting, and drivetrain seals, indicating that underlying issues have not been fully resolved. Earlier failures in 2021, 2020, and even 2019 reveal a troubling recurrence: front lower suspension arm pins and bushes showed up as wear items across three separate assessments, rear brake pads fell below safe thickness thresholds twice, and oil leaks were documented at least twice in the past four years. While the latest test did not fail outright, the persistence of these advisories—particularly the ongoing rear brake pad wear and front outer drive shaft boot deterioration—suggests a gradual degradation trajectory rather than isolated incidents. The vehicle's odometer reading of 142,789 miles against a 2004 model year yields an average annual mileage of approximately 6,490 miles, which aligns with expected usage for a car of this age but masks important nuances in how the wear has accumulated. The gap between the 2021 failed MOT and the subsequent 2022 pass spans nearly a full year, during which the same set of issues resurfaced, implying that repairs made prior to 2021 were insufficient to halt the progression of wear. There is no indication of unusually high mileage spikes or extended periods of inactivity; instead, the consistent presence of suspension arm bush wear, brake disc thinning, and oil leakage across multiple years points to chronic stress on these systems. The front inner and outer drive shaft constant velocity boots have shown progressive deterioration from their severe state in 2019 through 2022, while the rear subframe rubber bush also exhibited deterioration noted in 2019 and again in 2020. These findings suggest that the vehicle's chassis and drivetrain components have been subjected to cumulative strain over its lifespan. Buyers should treat the front lower suspension arm pins and bushes as a primary concern, as they appear repeatedly in advisory lists and could develop further play or binding that would manifest as harsh handling, pulling to one side, or increased vibration during cornering. During a test drive, listen for any clunking or creaking noises when traversing speed bumps or uneven surfaces, particularly around the front and rear suspension points, and pay close attention to whether the steering feels loose or shaky through the wheel. The rear brake disc condition remains a critical safety item—the 2022 MOT noted the disc as significantly and obviously worn, and the earlier 2020 failure confirmed brake pad thickness below the 1.5 mm threshold. A thorough brake pad inspection with a feeler gauge should be performed before purchase, ideally confirming pad thickness above minimum limits and checking for rotor scoring or glazing. Additionally, inspect the front outer drive shaft constant velocity boot for signs of leakage or complete detachment, as this component protects the internal seal and its failure can lead to accelerated brake disc and wheel bearing wear. Finally, verify that the front inner and outer suspension arm bushings move freely without grinding or sticking, and confirm that the rear subframe rubber bush shows no cracks or separation that might indicate structural weakness under load.
