Known Isuzu Holden Rodeo (shared) faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
The Denso high-pressure common rail fuel pump fitted to the 4JJ1-TC can suffer internal wear of the pump roller and plunger, releasing metal debris into the high-pressure fuel circuit. This debris contaminates the fuel rail, pressure regulator, and all four injectors simultaneously. A complete fuel system flush and replacement of the pump, fuel rail, pressure limiting valve, and injectors is required.
Symptoms to notice
Hard starting, especially when hot
Erratic idle with multiple cylinder misfires
Sudden severe power loss under load
Metal particles visible in fuel filter
Low or unstable fuel rail pressure readings
What to check
Ask about any history of hard starting, erratic running, or sudden power loss. Check fuel rail pressure at idle and under load using live data – low or erratic rail pressure at correct pump speed indicates pump wear. If a workshop inspection is possible: Connect a scan tool and check for injector balance rate deviations across all cylinders. Check for any metallic contamination by removing the fuel filter.
Where to look: High-pressure fuel pump mounted on engine block, top/side
Ask the seller
“Has the vehicle ever suffered hard starting, sudden power loss, or an unexplained need for injector work?”
“Has the fuel filter been changed at recommended intervals, and was any metallic contamination noted?”
“Has the high-pressure fuel pump ever been replaced or inspected for wear?”
02Rear Leaf Spring Bushing Deterioration
MinorCommonSuspension $350–$900 to fix
The D-Max uses a rear leaf spring suspension as standard on its ute body, with rubber bushings at the front eye and rear shackle of each spring pack. These bushings carry the full lateral, longitudinal, and vertical suspension loads of a laden ute and are exposed to road grime, UV, heat, and water ingress. The factory rubber compound hardens and cracks over time, accelerated by heavy towing, off-road use, and high mileage. Once the bushings deteriorate, differential movement between the spring eye and chassis mount causes metal-on-metal contact, producing knocking and banging sounds under acceleration, braking, or rough terrain. Worn bushings also allow the axle to walk fore and aft during acceleration, degrading rear traction and stability. Polyurethane aftermarket replacements last longer but can transmit more noise into the cab.
Symptoms to notice
Knocking or clunking from rear suspension under acceleration or braking
Banging sound when driving over sharp bumps or corrugations
Rear axle 'walking' or tramlining under hard acceleration
Visible cracking or deformation of rubber bushing material
Squeaking from rear suspension when loaded
What to check
With the vehicle on level ground, use a torch and mirror to inspect the front eye bushing (where the leaf spring bolts to the chassis hanger) and the rear shackle bushings for cracking, separation, or rubber extrusion. Rock the rear of the vehicle side to side and listen for clunking. If a workshop inspection is possible: On a hoist with the suspension hanging, check for visible movement at the spring eyes.
Where to look: Rear leaf spring front eye and rear shackle, both sides of rear axle
Ask the seller
“Have the rear leaf spring bushings been replaced?”
“Has the vehicle been regularly loaded near its payload capacity or used for towing?”
“Has there been any knocking or movement from the rear end?”
