Toyota Landcruiser 70 Series Common Problems

The LandCruiser 70 Series is Toyota's heavy-duty workhorse, sold here as the 76 wagon, 78 troop carrier and 79 single and double cab ute. Most used examples run the 4.5-litre 1VD-FTV single-turbo V8 diesel (2007 to 2024, with GXL utes built into 2025) and a 5-speed manual, with a diesel particulate filter (DPF) added in the late 2016 update. A 2.8-litre 1GD-FTV four-cylinder arrived in late 2023 with a 6-speed automatic, and a manual followed. Older trucks carry the 4.2-litre 1HZ diesel, the 1HD-FTE turbo-diesel or the 1FZ-FE petrol six. It is tough and simple but crude, and hard work, overloading and poor modifications show up on the used market.

DPF blockages and regeneration problems (4.5L 1VD-FTV, 2016 to 2025)

V8 trucks built after the late 2016 update have a DPF. Low-speed property work, idling and short trips keep exhaust temperatures too low for the filter to burn off soot, so it slowly clogs. Symptoms are a DPF or check engine light, smoke, reduced power and limp mode. Regular highway runs prevent most of it, and the recall work added a manual regeneration mode. Some owners remove the DPF, which is not legal for road use. Toyota has been reported as saying the 2.8 1GD-FTV is unaffected by the DPF problems that hit earlier 2.8 utes and SUVs, but it is too new for a clear fault pattern.

Fuel system, injector and EGR faults (4.5L 1VD-FTV, 2007 to 2025)

The V8's common-rail system dislikes water and dirt in the fuel. One used-car guide lists pressure sensors and suction control valves as the common, cheaper faults, and high-pressure pumps and injectors as the expensive ones. Injector seals can also leak, letting combustion gas overheat the injector. Signs are rough or uneven idle, misfires, diesel smell, black smoke under load and limp mode. Inlet and EGR passages can also clog with soot. Specialists advise changing the fuel filter about every 10,000 km and fitting a fuel pre-filter for remote work. A full fuel system overhaul can cost roughly $5,000 to $10,000.

Oil use and dust past the airbox (4.5L 1VD-FTV, 2007 to 2025)

Toyota guidance quoted by owners says the V8 is expected to use some oil, more so in severe use. Some owners of early 2007 to 2009 trucks reported noticeable use between services that settled down with age. Higher use under heavy towing is also reported. The bigger risk is dust: owners and Australian 4WD publications report that the factory airbox seal lets dust past the filter, which can upset the airflow sensor and, some owners report, wear the turbo and the engine's rings and bores. A greased or aftermarket airbox seal is the usual fix.

Clutch slip, synchro crunch and fifth gear wear (5-speed manual, 2007 to 2025)

The factory clutch copes with stock power, but towing, heavy loads and tunes wear it out early. Some owners report slip when towing or by around 100,000 km. Signs are revs rising without matching speed and a high bite point. Heavy-duty clutch kits run from about $1,500 to $3,000 before labour. The gearbox can crunch between second and third, which owners often blame on worn synchros or the wrong gear oil, so check that the grade Toyota specifies has been used. One used guide reports fifth gear failures on trucks that tow in fifth. The same guide names the clutch as a weak point on the earlier 1HD-FTE trucks.

Narrow rear track and front wheel bearing wear (V8 models, 2007 to 2025)

When Toyota fitted the V8 it widened the front track but kept the old rear axle, so the rear track is about 95 mm narrower than the front. The rear tyres don't follow the front ruts, so the truck wanders on sand and rutted tracks and can feel unstable when loaded. Fixes range from different wheel offsets front and rear to wider rear axle housings, which cost roughly $6,000 to more than $10,000 fitted. Front wheel bearings wear faster on heavy, big-tyred trucks: listen for a hum or growl that rises with speed. Expect roughly $500 a side at a mechanic.

Chassis cracks, spring sag and steering wobble (hard-worked trucks, 1999 to 2025)

Overloading and fast driving on rough roads can crack the chassis where the rear spring hanger is welded to the frame, though this is rare on trucks kept within GVM. A clunk under load or a rear end that wanders in corners are warning signs, and fresh welds there deserve a close look. Rear leaf springs also sag when trucks run over GVM. At the front, worn tie rod ends, ball joints, swivels and bushes can cause a speed wobble, especially on lifted trucks with big tyres. Owners of 1HZ and V8 trucks report curing it with new tie rod ends and bushes, not just a heavier steering damper.

Rust and leaking door seals (all models, 1990 to 2025)

Rust is not widespread, but it appears under the windscreen, around the snorkel, in the A-pillars and rear quarters, and in the chassis of ex-mine and coastal trucks. A-pillar rust repairs can be very expensive. The factory door seals let in dust, wind noise and diesel fumes, and blocked door drains can let water sit inside the doors after crossings. Aftermarket bulb seals cost a couple of hundred dollars.

Recalls and safety

Two recalls stand out. ABS-equipped 70 Series built from May 2012 to March 2014 were recalled because the brake hose bracket on the front differential could crack and leak brake fluid. In 2020 Toyota recalled DPF-equipped trucks built from June 2016 to November 2018 over a fire risk from dry grass caught near the DPF during regeneration: the fix is a revised heat shield and a manual regeneration mode.

Buying a used Toyota LandCruiser 70 Series? What to check

• Service history: Look for oil changes on time and fuel filter changes about every 10,000 km. Gaps on a worked truck are a red flag.
• Cold start and smoke: Start it cold. Black smoke points to injectors or the DPF, white smoke to coolant, blue smoke to oil or turbo seals.
• DPF and tune: On 2016 and later V8s, ask whether the recall was done and whether the DPF has been removed or the engine tuned.
• Airbox: Pull the air filter and check the clean side of the airbox and intake for dust.
• Clutch and gearbox: Pull away in a high gear up a hill to test for slip, and check for crunching from second to third.
• Chassis and springs: Inspect the rear spring hangers for cracks or fresh welds, and check the compliance plate and paperwork for any GVM upgrade.
• Front end: Drive at 80 to 100 km/h for any wobble or shimmy, and check the wheels for play and bearing noise.
• Rust: Check under the windscreen, the A-pillars, around the snorkel, the rear quarters and the chassis, especially on ex-mine trucks.
• Oil use: Check the dipstick and ask how much the owner tops up between services.

The verdict

A well-serviced, unmodified V8 that has not been overloaded is the safe pick. Pre-DPF trucks from 2007 to 2016 suit remote touring and light-duty use without long highway runs. DPF trucks from late 2016 on are fine if they get regular highway kilometres and have had the recall done. The 2.8 four-cylinder auto suits buyers who want an automatic, but it has less history. Older 1HZ and 1HD-FTE trucks are about condition: rust, chassis and front end first. Avoid ex-mine, heavily tuned or overloaded examples without paperwork.
