Unstoppable workhorse if the rust hasn't won
A rugged, no-nonsense Japanese 4x4 built from 1984 to 2002, the Fourtrak earned a devoted following among farmers, horse owners, and rural workers as a cheaper, more reliable alternative to the Land Rover Defender. Nicknamed 'Dai-rot-through' for its corrosion tendency, surviving examples with solid chassis are increasingly sought after as tough, practical workhorses.
We track 5 known issues across the Daihatsu Fourtrak range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

F70 (1985–2002) — Engine options included the 2.8L Diesel.
The Fourtrak suffers from severe structural corrosion at critical mounting points including subframe, suspension, and body mounting areas. MOT data shows failure rates 259 times higher than the fleet average, indicating this is a fundamental design weakness rather than normal age-related deterioration. The corrosion affects load-bearing areas within 30cm of suspension mounting points, compromising structural integrity. This is particularly severe on vehicles used off-road or in coastal areas due to salt exposure.
Structural corrosion at mounting points represents a critical safety risk. Failure can cause suspension collapse, loss of steering control, or catastrophic structural failure. Repair typically requires welding new metal sections or complete subframe replacement. Costs routinely exceed the vehicle's value, making many examples uneconomical to repair.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
The Fourtrak steering system exhibits excessive wear rates, with MOT data showing free play failures at 214 times the fleet average and ball joint wear at 47 times normal rates. The recirculating ball steering box, track rod ends, and ball joints wear rapidly due to the vehicle's agricultural design and off-road usage patterns. This creates dangerous levels of steering play and poor road holding, particularly at motorway speeds.
Worn steering components create a significant safety risk at speed, with poor directional stability and potential for sudden loss of steering control. The vehicle becomes tiring to drive on long journeys and may fail MOT tests. Complete steering overhaul typically required every 80,000-100,000 miles.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
Multiple suspension components wear at accelerated rates on the Fourtrak, with MOT data showing failures at 41-43 times the fleet average for bushes, joints, and pins. The solid axle design with leaf springs places high loads on rubber components, while the vehicle's off-road capability means many examples experience harsh usage that accelerates wear. Shock absorber bushes, suspension pins, and various joints require regular replacement.
Worn suspension components significantly affect ride quality, handling, and tyre wear patterns. The vehicle becomes uncomfortable on poor road surfaces and may feel unstable at speed. Progressive failure of multiple components is typical, requiring comprehensive suspension overhaul rather than individual component replacement.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Wheel bearings on the Fourtrak fail at 45 times the fleet average rate according to MOT data. The solid axle design and heavy-duty usage patterns place high loads on wheel bearings, while the vehicle's age means many examples have original bearings approaching or exceeding their service life. Front wheel bearings are particularly susceptible to wear from steering loads and off-road use.
Worn wheel bearings create noise, vibration, and in severe cases can cause wheel wobble or complete bearing collapse. A collapsed bearing can cause loss of vehicle control and wheel separation. Early replacement when wear is detected prevents more expensive hub damage and maintains safe operation.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The Fourtrak suffers from widespread body corrosion that reduces structural rigidity at 113 times the fleet average according to MOT data. The body structure, particularly around door frames, sills, wheel arches, and the rear body, corrodes extensively due to poor rust protection and the vehicle's utilitarian design. This affects both structural integrity and weather sealing, with many examples developing significant rust holes.
Body corrosion affects structural integrity, weather sealing, and vehicle safety. Extensive corrosion can cause MOT failure and make the vehicle uneconomical to repair. Door frames and structural areas require professional welding repair, while cosmetic rust can be treated with localised bodywork. Progressive deterioration is typical without intervention.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.

Based on 10k real DVSA MOT tests, the Daihatsu Fourtrak fails more often than average on several items. The biggest outlier is track rod ends worn at 4507x the fleet average, followed by fixings missing or insecure (780x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Daihatsu Fourtrak MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 6k miles) typically costs £45–£65 at an independent garage.
The bigger-ticket items to budget for include timing belt (£350–£500).

The Daihatsu Fourtrak has some well-documented weak points, including 1 safety-critical issue that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. The 1993-2002 models with the 2.8-litre turbo diesel intercooled engine are the most desirable, offering the best combination of power, torque, and towing ability. Later 1998-2002 examples benefit from minor refinements and are likely to have less accumulated rust. Any Fourtrak should be bought on condition rather than year — a well-maintained 1995 will be better than a neglected 2001. Always inspect the chassis thoroughly.
