2005 Mercedes CLK 1.8L Petrol · YB05 UXL

A dangerous front suspension condition dominates the recent MOT history – the 2025‑11‑23 test recorded an off‑side front suspension arm ball joint judged likely to detach, accompanied by an excessively worn arm pin or bush and deteriorating rear brake hoses, all classified as a failure. That failure was followed by a pass two days later that still listed corrosion on both anti‑roll bars, coil‑spring rust and minor lamp product build‑up, indicating that while the vehicle cleared the test, the underlying structural and corrosion issues remain unresolved. At 59,886 miles for a 2005 model the annual average is roughly 2,850 miles, well below typical usage for a car of this age. Such low mileage often points to extended periods of inactivity, which can accelerate the ageing of rubber components, bushings and seals even when wear from distance is minimal. The MOT record shows no entries before 2023, so any earlier defects are unknown; the recent pattern suggests that age‑related deterioration, rather than high mileage wear, is the primary concern. The front suspension arm and ball joint should be inspected for play, clunking noises over bumps and any steering wobble; replacement of the arm, bushings and ball joint is advisable before further road use. The rear brake hoses, noted as slightly deteriorated on both sides, merit a close visual check for cracking, swelling or fluid seepage, and the pedal should feel firm without sponginess. Corroded anti‑roll bars and coil springs should be examined for looseness, rust‑induced weakening or cracks that could affect handling and ride height, while the defective exhaust mounting may manifest as rattles or excessive vibration under acceleration. Given the combination of structural wear, corrosion and ageing rubber, a comprehensive pre‑purchase inspection by a qualified mechanic is essential. The buyer should confirm that any remedial work on the front suspension and brake hoses has been carried out, verify the integrity of the anti‑roll bar linkages and coil springs, and test‑drive the car for steering pull, uneven braking and abnormal noises. Addressing these items now will mitigate the risk of sudden failure and bring the vehicle closer to a reliable road‑worthy condition.
