2017 Isuzu D-MAX 1.9L Diesel · YY17 UGV

The 2017 Isuzu D-Max passed its most recent MOT on the 15th of June 2026 at 115,087 miles, but the record reveals a worsening trend in corrosion and wheel bearing wear. The tester flagged corroded brake pipes covered in grease across the entire system, alongside slight play in both front wheel bearings. These are not new issues. Brake pipe corrosion has appeared consistently since the July 2025 test at 102,878 miles, where multiple pipes were noted as corroded and greased at the rear. The application of grease over corroded brake lines is a known masking practice that conceals the true extent of deterioration and suggests previous owners opted for cosmetic concealment over proper repair. Front wheel bearing play has also recurred in three consecutive tests since 2025, indicating progressive wear that has not been addressed. The vehicle has covered roughly 12,787 miles per year over nine years, which is high for a light commercial vehicle of this age. The mileage progression is steady, jumping from 64,916 miles in July 2022 to 115,087 miles by June 2026, with no significant gaps suggesting long periods of inactivity. This consistent high-mileage use places sustained stress on consumable components, particularly brakes, suspension bushes, drivetrain mounts, and steering linkages. The 2023 test at 75,530 miles recorded a clean pass, but the subsequent two tests show a marked decline in mechanical condition, suggesting accelerated wear has set in as the vehicle has aged past the 100,000-mile threshold. A buyer should prioritise a thorough underbody inspection focused on the structural integrity of the brake pipe runs, particularly along the rear axle and front-to-rear lines. Corroded pipes demand immediate replacement with copper-nickel lines, and any residual grease must be stripped away to assess the true wall thickness. The recurring front wheel bearing play warrants physical jacking of the front axle to check for roughness or excessive movement, as failure at speed is a serious risk. Suspension bushes, coil springs, and shock absorbers should be examined for deterioration consistent with high commercial use. The chassis and cross-members require close scrutiny for corrosion, especially around mounting points and box sections. Tyre condition and remaining tread depth should also be verified, given the vehicle's heavy workload.
