2007 Chrysler-Jeep Cherokee 2.5L Diesel · AM55 DOR

The most recent MOT test on 2026-02-11 returned a clean pass, but the presence of persistent advisories—particularly around the front suspension ball joints and upper suspension arms—indicates a concerning maintenance trend rather than improvement. While the vehicle has passed each subsequent MOT since then, the recurring reports of slight play in multiple ball joints and suspension arm joints suggest progressive wear, which could escalate into binding or failure if left unaddressed. The offside front suspension arm and inner track rod end ball joint advisories from 2016 and 2018, alongside the front upper suspension arm ball joints from 2025 and 2026, highlight a pattern of wear that demands proactive intervention. These issues are not merely cosmetic; excessive play in suspension components can lead to uneven tyre wear, reduced handling stability, and increased risk of suspension failure under load, particularly at higher speeds or during cornering. The vehicle’s recorded mileage of 378,289 miles at 19 years old represents an exceptionally high annual usage rate of approximately 19,910 miles per year, which is far above the average for its age. Such sustained high mileage accelerates wear on critical components like brakes, tyres, suspension, and drivetrain elements, as evidenced by the repeated tyre wear advisories and oil misting in the shock absorbers. The absence of significant service intervals or long periods of inactivity also contributes to fluid degradation, such as brake fluid and differential fluid, which can become less effective over time. The rapid mileage accumulation may also suggest frequent or aggressive driving conditions, further stressing the suspension and drivetrain components, which could explain the observed wear progression. For a prospective buyer, the most critical areas to inspect are the front suspension components, particularly the ball joints, upper suspension arms, and track rod ends. During a test drive, listen for unusual clunking or rattling noises from the front suspension, especially when negotiating bumps or turning sharply, as these may indicate loose or worn suspension bushings or ball joints. Inspect the front tyres for uneven wear patterns, such as edge wear or central wear, which could confirm the advisories of tyre wear approaching legal limits. Check for any oil leaks around the front suspension mounts or shock absorbers, as misting in the shock absorbers from 2025 suggests potential internal damage or seal failure, which may require replacement. Additionally, verify that the steering wheel does not exhibit excessive play or binding, as this could correlate with the reported ball joint issues. Beyond the suspension, the high mileage and age warrant thorough checks on the braking system, drivetrain, and fluid condition. Inspect the brake discs and pads for signs of corrosion, binding calipers, or excessive wear, as prolonged standing or high-mileage use can lead to moisture ingress and rusting. Test the brake pedal for firmness and ensure there is no sponginess or excessive travel, which could indicate fluid degradation or air in the system. The differential and transmission fluids should be checked for contamination or burn marks, as high-mileage vehicles are more susceptible to these issues. Finally, examine the vehicle’s tyre sidewall for signs of perishing or cracking, which can compromise tyre integrity over time, even if the tread remains legal. Given the vehicle’s usage profile, a comprehensive service history review is essential to confirm whether scheduled maintenance—such as fluid top-ups, suspension component replacements, and brake system servicing—has been conducted. If possible, request a copy of the service book to verify adherence to manufacturer-recommended intervals.
