2004 Jeep Cherokee 2.5 CRD Sport 2.8L Diesel · RX04 KBU

The most recent MOT assessment on 9 May 2026 resulted in a pass, but the vehicle's maintenance history reveals a concerning pattern of recurring mechanical issues and structural degradation. While the vehicle has passed its last few tests, the trend shows a persistent struggle with engine oil leaks and drivetrain component wear. The history is marked by several dangerous and major failures, particularly regarding braking systems and structural corrosion, suggesting that while the vehicle is currently roadworthy, it has been subject to reactive rather than proactive maintenance. The presence of a severely deteriorated nearside front inner drive shaft constant velocity boot in the latest test indicates that mechanical components are reaching the end of their service life and require immediate attention to prevent more costly failures. With 216,085 miles recorded over approximately 22 years, the vehicle has averaged roughly 9,822 miles per year. This is a typical usage profile for a diesel 4x4 of this era, suggesting the engine and drivetrain have been subjected to consistent, moderate workloads rather than extreme heavy-duty use or long periods of neglectful standing. However, at this high mileage, the mechanical integrity of all rubber components, seals, and suspension bushings is naturally compromised. The cumulative mileage means that wear on consumables such as the clutch, fuel injection system, and turbocharger is likely significant, and the historical record of oil leaks suggests that gaskets and seals are failing due to age and thermal cycling. A prospective buyer must exercise extreme caution regarding the documented oil leaks, which have appeared as both major failures and persistent advisories over several years. You should inspect the engine bay for signs of fresh seepage and check the ground beneath the vehicle after it has been stationary. Furthermore, the recent advisory regarding the nearside front inner drive shaft CV boot is a critical warning; if this boot fails completely, grease will escape and grit will enter the joint, leading to a loud clicking or clunking noise during low-speed turns and eventual driveshaft failure. You should also pay close attention to the braking system, as the history shows a pattern of thin pads, pitted discs, and corroded brake hoses. During a test drive, listen for any grinding from the rear or a spongy pedal feel, which could indicate further degradation of the hydraulic lines or binding calipers. Structural integrity is perhaps the most significant concern based on the 2022 failure, which noted excessive corrosion on the nearside and offside rear suspension component mountings and inner sills. While the vehicle has passed since then, you must conduct a thorough physical inspection of the chassis and sills for any signs of bubbling paint, surface rust, or structural rot. Given the age and high mileage, also verify the service history to ensure that fluids, particularly the differential oils and engine coolant, have been changed according to schedule. Check the condition of all suspension bushes and tie rod ends for play, as the history shows these components have been borderline for several years. Any movement in the steering or uneven tyre wear during your test drive will confirm that the suspension geometry is compromised.
