What to look out for
Serious issue
Look for hairline cracks radiating from the inner rolled section of the eye.
Rear Leaf Spring Eye Cracking and Bushing Collapse
The GU Patrol's rear suspension uses a multi-leaf spring pack with a rolled steel eye at the front mounting point. On high-mileage or heavily loaded vehicles — particularly those used for towing or carrying canopies and drawers — the spring eye develops fatigue cracks at the inner radius of the rolled eye. In parallel, the polyurethane or rubber bush inside the eye collapses and allows metal-to-metal contact, accelerating crack propagation. A cracked spring eye can fail completely and allow the axle to shift rearward under braking, causing a sudden and dangerous loss of directional control. Vehicles with aftermarket lift packs fitted at increased spring rate are at elevated risk.
What you would notice
Costly issue
Inspect the front differential pinion flange and the nose of the differential casing for gear oil weeping or a dried oil film.
Front Differential Pinion Seal Leak
The front differential pinion shaft seal on the GU Patrol's Dana 30/Patrol front axle is a high-wear item. The pinion flange rotates at driveshaft speed and the rubber lip seal degrades from heat and UV exposure, typically beginning to seep between 80,000 and 150,000 km. The leak is progressive: initially a light film of gear oil on the front of the diff casing, eventually building to active dripping if ignored. Running the differential with low oil from a leaking pinion seal causes pinion and crown wheel bearing wear and ultimately differential failure. The seal is inexpensive but requires correct flange nut preload to be re-set on reassembly.

Costly issue
Run your fingers along the roof gutters and around the rear quarter glass rubbers looking for bubbling.
Rust in gutters, sills, rear quarters and chassis (Y61)
Y61 Patrols rust in predictable places: roof gutters, around the rear quarter windows and barn doors, sills, floor pans, body mounts and the chassis rails/rear crossmember. NZ examples that have lived on beaches (a classic Patrol life) or towed boats are the worst affected, and Japanese-import Safaris can carry hidden salt-road corrosion. The mechanicals — especially the legendary TD42 — will outlast the body, so on an old Patrol the body and chassis condition is the real value driver.
What you would notice
Costly issue
Listen from inside the vehicle during a road test at 60–80 km/h in 2H for a speed-related howl that does not change with engine rpm.
Transfer Case Front Input Bearing and Oil Seal Failure
Both Y60 and Y61 Patrols use a twin-stick transfer case (Borg Warner or Nissan NP233/NP205 equivalent). The front input shaft bearing is a known wear point: it runs in a housing exposed to heat cycling and off-road vibration, and the factory grease interval is rarely observed. Bearing failure produces a howl that varies with vehicle speed independent of gear selection. Simultaneously, the front and rear output shaft oil seals harden and crack, allowing gear oil to migrate into the front propshaft flange and onto the rear brake drums. Total transfer case oil loss can occur quickly once the seals breach, leading to catastrophic bearing and gear failure.
What you would notice
Costly issue
Drain and inspect the transfer case oil for a metallic sheen or fine metal particles, which indicate chain and sprocket wear.
Transfer Case Drive Chain Wear and Slipping
The Patrol Y61 uses a Borg Warner transfer case with an internal drive chain to distribute torque between the front and rear outputs. The chain is lubricated by the transfer case oil, and over high mileage — especially where oil changes have been neglected or the vehicle has been used heavily in 4WD — the chain links elongate through wear and the sprocket teeth become rounded. A worn chain produces vibration and shudder felt through the driveline in 4WD, and in advanced cases the chain can skip over the sprockets, causing intermittent loss of drive to either axle. The failure is accelerated by off-road use that demands sustained 4WD engagement.
What you would notice
Costly issue
Inspect the axle tube where it exits the differential housing for oil weeping.
Front Axle Birfield Joint Failure and Axle Seal Leaks
The solid front axle on both Y60 and Y61 Patrols uses Birfield constant-velocity joints enclosed in the hub. The Birfield cage and balls crack under sustained off-road stress, particularly when the axle is lifted beyond the factory geometry or when the grease nipple service interval is missed. Once the cage cracks, grease is expelled and metal-on-metal wear accelerates rapidly. The inner axle tube oil seal (differental side) also weeps on high-mileage examples, allowing diff oil to migrate along the axle shaft and contaminate the Birfield grease cavity — effectively starving the joint. Failure of the Birfield joint results in a complete loss of drive to the affected front wheel and potential for the shaft to disengage at speed.

03Transfer Case Hi/Lo Engagement Fork Wear
The GU Patrol's part-time transfer case uses a mechanical shift fork to move the range sleeve between high and low range. The fork is manufactured from an aluminium alloy and the engagement pads wear progressively, especially on vehicles used frequently off-road or where the shift is made at speed rather than at a dead stop. Worn fork pads result in incomplete engagement of low range, causing the transfer case to pop out of 4Lo under load — the classic symptom is the vehicle unexpectedly returning to neutral under a steep hill-climb load. In advanced cases the fork can fracture, requiring full transfer case disassembly.

09Front-end 'death wobble' — kingpin preload and worn steering components (Y61)
Live-axle Y61 Patrols, particularly lifted or hard-worked examples, can develop a violent front-end shimmy at open-road speed after hitting a bump — the infamous death wobble. Forum consensus and workshop experience point to kingpin (swivel hub) preload as the first thing to check, followed by panhard rod bushes, tie rod ends and wheel balance. It is fixable and usually not hugely expensive, but a truck that wobbles has often been worn in several places at once, and big aftermarket tyres make it worse.

10Front Axle Universal Joint Wear and Vibration
11Brake Caliper Guide Pin Seizure
The front and rear brake calipers on the Y61 Patrol use sliding guide pins to allow the caliper body to float as the brake pads wear, ensuring even pad contact across the rotor face. The guide pin rubber dust boots deteriorate with age and road exposure, allowing moisture and road salt to enter the pin bore. The steel guide pins then corrode inside their aluminium carriers, seizing in place. A seized guide pin prevents the caliper from sliding freely, so only the piston-side pad contacts the rotor effectively, causing rapid and uneven pad wear, rotor scoring, and a vehicle that pulls to one side under braking. In severe cases the seized caliper drags permanently, generating heat that can boil brake fluid and cause brake fade.

Can't confirm for this car
The TB48DE inline-six has a known weak point at the rear pair of cylinders (cylinders 5 and 6) where the head gasket is most susceptible to failure. The failure mode is typically a coolant-to-combustion breach rather than an oil leak, driven by localised thermal stress at the rear of the long cylinder block where coolant flow is weakest. Symptoms closely mimic those of a failing radiator or thermostat, which can delay correct diagnosis. Overheating events — even brief ones from a faulty thermostat — accelerate the gasket failure. Detection via a combustion gas test of the coolant reservoir is the most reliable non-invasive diagnostic.
Example of the part — not this vehicleA used multi-layer head gasket. Discolouration between a cylinder and a water gallery is the tell.

The 2.8L RD28T turbo diesel injection pump shaft seal and front cover gasket are known to weep fuel and oil with age. The pump is mechanically driven and the seal wears over high mileage. Fuel contamination of engine oil is a secondary risk if shaft seals fail fully. Less catastrophically dangerous than ZD30 issues but a common finding on higher-mileage RD28T GU Patrols imported into NZ as JDM units.
A common-rail diesel injector. Contamination damages the nozzle at the tip.

Does not apply
Does not apply
Nissan marketed the Y62's 7-speed automatic as sealed-for-life, but Australian Patrol specialists strongly disagree — vehicles used for towing or hot-climate touring need fluid changes as often as every 30,000-50,000 km, and the torque converter is the known weak point under prolonged heavy towing. Symptoms include shift delays under load, shudder, and gear ratio fault codes (P0729 for 6th gear is a known one, often speed-sensor related). Most Y62s in NZ tow something big, so service history matters more than the odometer.

Does not apply07VK56VD VVEL Actuator Motor Failure
Does not apply
Does not apply
The VVEL system on the VK56VD uses electric DC actuator motors on each cylinder bank to continuously vary valve lift and duration. These actuator motors are prone to internal brush wear and bearing failure, typically presenting between 80,000 and 150,000 km. When a motor fails the ECU detects the fault, stores a P000A or P000B code, and restricts the engine to a fixed low-lift limp mode resulting in a dramatic loss of power. Replacement requires removal of the intake manifold and valve covers, making labour costs significant.

08VK56VD HPFP Pulsation Dampener Diaphragm Rupture
Does not apply
Does not apply
The VK56VD direct-injection engine uses a high-pressure fuel pump with an integrated pulsation dampener whose flexible metal or rubber diaphragm absorbs cyclic pressure pulses generated by the cam-driven pump. This diaphragm can rupture or fatigue over time, causing uncontrolled fuel pressure oscillations in the high-pressure rail, rough idle, hesitation under load, and erratic fuel delivery. In severe cases of diaphragm rupture, fuel vapour can enter the engine bay. Symptoms closely mimic other fuelling faults and definitive diagnosis requires monitoring live high-pressure fuel rail data for oscillation signatures.

09VK56 5.6 V8 extreme fuel consumption and limited touring range (Y62)
Does not apply
Does not apply
Not a defect but the defining ownership cost: the 5.6-litre petrol V8 routinely returns 14-18 L/100km around town and well over 20 L/100km towing, and forum threads are full of owners shocked by real-world figures versus the official claim. With the 140-litre tank that still limits remote touring range, which is why long-range tanks and careful trip planning are common. Budget realistically — at NZ petrol prices a towing Y62 can cost more in fuel than its finance payment. The engine itself is robust when serviced, making this a wallet problem rather than a reliability one.

10VK56VD MAP Sensor Failure & Rough Idle
Does not apply
Does not apply
The intake manifold absolute pressure sensor on the VK56VD 5.6L V8 is susceptible to contamination from oil vapour and carbon deposits drawn through the PCV system. Sensor drift or complete failure causes the ECU to receive incorrect manifold pressure data, leading to an incorrect fuel calculation, rough idle, erratic fuel trims, hesitation on light throttle, and an illuminated check engine light. The sensor itself is a relatively inexpensive component, but access on the VK56VD may require partial intake disassembly, adding to labour cost.

01Transfer case encoder motor failure — stuck in Hi or Lo range
Does not apply
Does not apply
The Y62 Patrol uses an electronic encoder motor to shift the transfer case between 2H, 4H, and 4L. The encoder motor and its position sensor are prone to failure, causing the transfer case to stick in its current range or refuse to shift. The vehicle may remain stuck in 4WD (causing drivetrain binding on-road) or in 4Lo (preventing road driving). This is a documented fault on Y62 Patrols in NZ/AU from around 80,000 km onward, with replacement encoder motors required.

Higher-spec Y62s (Ti-L and similar) use Nissan's Hydraulic Body Motion Control — interlinked hydraulic suspension instead of conventional sway bars. It rides beautifully when healthy, but the system's rams, lines and accumulators can leak or lose pressure with age and off-road use, producing a leaning, wallowing truck and warning messages. Parts are dealer-priced and repairs are specialist work; some owners in AU/NZ convert to conventional springs and sway bars instead. Check which suspension the specific car has before valuing it.

The Y62 Patrol is a very heavy vehicle (over 2,700 kg GVM) and the front wheel bearings carry significant load, particularly on vehicles used for towing or frequent off-road work. Front wheel bearing failure is documented from 80,000–150,000 km on higher-use examples. The hub-integrated bearing unit requires pressing out and replacement rather than simple repacking. Bearing failure left unaddressed can progress to wheel wobble and, in severe cases, wheel separation risk.
