2009 Land Rover Range Rover 3.6L Diesel · YC09 RZB

Progressive underbody corrosion and accelerating suspension degradation define the mechanical trajectory of this Range Rover. Although the vehicle secured a valid MOT certificate on 5 May 2026 following a same-day rectification for defective front headlamp aim, the overall test history highlights an expanding list of chassis advisories. Corrosion across the rear subframe and both rear upper suspension arms has become a persistent concern, compounded by worn front suspension arm bushes and play in the anti-roll bar linkages. Furthermore, historical failures for critically low rear brake pad thickness and recurring headlamp alignment faults point to a vehicle where heavy consumable components regularly operate at their absolute working limits. Amassing 185,187 recorded miles over roughly 17 years translates to an average annual accumulation of approximately 10,900 miles, which represents typical usage for a large executive 4x4. The testing record shows consistent year-on-year mileage progression without prolonged periods off the road. However, carrying this considerable kerb weight over higher mileages inevitably takes a toll on chassis structural pressings, bush rubber compounds, and suspension articulation points. At this age and mileage, factory underseal coatings have largely degraded, allowing road grime and moisture to accelerate surface corrosion on structural components. A prospective buyer must arrange for a thorough underbody inspection on a vehicle lift before making a commitment. Particular focus must be directed to the rear subframe and both rear upper suspension arms to verify whether the recorded rust remains superficial surface scaling or if deep corrosion has compromised structural integrity or mounting points. During a road test, listen carefully for heavy clunking or dull thuds from the front end when traveling over speed bumps or rough road surfaces, as these symptoms indicate worn front suspension arm bushes that require replacement. Attention should also be paid to the braking system and suspension geometry. Verify that the brake pedal offers a firm, progressive feel without judder or pulling to one side, ensuring brake discs and pads have adequate thickness following the previous dangerous failure for severe friction material wear. Observe the vehicle's tracking on straight roads, as historical advisories for uneven tyre edge wear suggest suspension alignment is out of specification due to worn anti-roll bar linkage ball joints and tired chassis bushes. Finally, check that the front headlamps auto-level correctly, given that misaligned beam patterns have triggered multiple MOT failures.
