2018 Mercedes-Benz GLC 2.1L Diesel · HR08 JOT

Recurring suspension and tyre wear patterns define the mechanical history of this Mercedes-Benz GLC, which secured a pass on 5 March 2026 despite an advisory regarding rear brake disc wear. While the vehicle has maintained a consistent record of passing its annual inspections, the data reveals a persistent trend of front-end component degradation. Specifically, the offside front suspension arm ball joint has been flagged with slight play in both the 2024 and 2025 examinations, suggesting that this component has reached a threshold of wear that requires monitoring or replacement. When combined with the repeated advisories for edge-worn front tyres, the record indicates a potential need for a professional geometry alignment check to ensure the suspension setup is not accelerating tyre degradation. The recorded mileage of 59,415 miles over an eight-year period equates to an average annual usage of approximately 7,427 miles. This rate of accumulation is consistent with standard domestic use and suggests the vehicle has not been subjected to the high-stress cycles typical of commercial or long-distance motorway fleets. There are no significant gaps in the testing history, confirming that the vehicle has been presented for annual inspection without interruption since its first test. This steady usage profile means that while the drivetrain has not been overworked, the suspension and braking components have been subjected to regular, moderate cycles of heat and movement, which aligns with the wear items identified in the DVSA records. During your test drive, pay close attention to the front suspension performance by navigating over uneven road surfaces or speed humps at low speeds. Listen for any metallic knocking or clunking sounds originating from the front wheel arches, which would indicate that the play previously noted in the offside front suspension arm ball joint has progressed to a point of failure. Additionally, test the steering for any tendency to pull to one side or any vibration through the steering wheel at motorway speeds, as these symptoms often correlate with the uneven tyre wear patterns previously recorded by inspectors. Regarding the braking system, the current advisory for worn rear discs necessitates a visual inspection of the disc faces for scoring, lip formation, or signs of heat glazing. During the test drive, apply the brakes firmly from moderate speed in a safe area to check for any pedal pulsation or judder, which can indicate warped discs or uneven pad contact. As the front tyres have been a recurring point of concern, verify that the current set is matched and that the tread depth is uniform across the width of each tyre. Ensuring these specific areas are addressed will be essential for maintaining the vehicle's roadworthiness moving forward.
