2007 Renault Master 2.5L Diesel · OV07 NBN

Recurring suspension and drivetrain deterioration defines the mechanical history of this Renault Master, which passed its most recent MOT on 23 June 2025 following a failure for a split constant velocity boot and a non-functional lamp. The record reveals a persistent pattern of wear, particularly regarding the front suspension ball joints, which have been flagged as having slight play in every annual inspection since 2023. While the vehicle remains roadworthy, the consistent nature of these advisories suggests that the front-end components are reaching the end of their operational lifespan and will likely require replacement rather than continued monitoring. At 138,266 miles over 19 years, the vehicle has averaged approximately 7,277 miles per year, a rate consistent with typical light-commercial usage. This level of activity indicates that the vehicle has not sat stagnant for extended periods, which generally helps prevent the seizure of mechanical linkages and the degradation of rubber seals often seen in long-term storage. However, the consistent accumulation of mileage on a heavy-duty chassis of this age means that high-stress components, specifically those related to steering and suspension geometry, have been subjected to significant cyclical loading. Prospective buyers should prioritise a thorough inspection of the front suspension during a test drive, listening specifically for metallic knocking or clicking sounds when navigating uneven surfaces or executing tight turns at low speeds. Given the recurring reports of slight play in the lower ball joints, any vagueness in the steering or a lack of self-centring feel when exiting a corner should be treated as a sign that these components have exceeded their tolerance levels. Additionally, the history of constant velocity boot failure necessitates a visual check of the inner and outer driveshaft gaiters for fresh grease spray, which would indicate a recurring issue with joint protection. The headlamp lens condition noted in the most recent test should be evaluated for light output efficiency during a night-time drive, as surface clouding or product residue can significantly diminish visibility. Furthermore, the previous failure involving a structural tyre defect highlights the importance of inspecting all four tyres for sidewall bulging or tread separation, as the weight-bearing demands on a vehicle of this type can accelerate the failure of aged rubber. Any vibrations felt through the steering wheel at motorway speeds should be investigated immediately, as these may point to underlying issues with the wheel bearings or the previously flagged suspension components.
