Overview

Two distinct trucks share this body: the 100 series (independent front suspension, full-time 4WD) and the live-front-axle 105 series (part-time 4WD, beloved by remote/outback owners for its solid-axle simplicity). The standout engine is the 4.2L 1HD-FTE turbo diesel; the 105 also offered the indestructible naturally-aspirated 1HZ. Petrol buyers got the 4.5L 1FZ-FE six (early) then the 4.7L 2UZ-FE V8. All are revered for longevity but they are now old, high-km vehicles - condition and service history matter enormously, and the diesel's timing belt and the V8's belt are scheduled items, not lifetime.

Timing chain / belt / gear
Belt-driven camshaft (replace ~100,000km) with gear-driven ancillary train

Pros

  • Strong, torquey and genuinely long-lived (400k+ km common)
  • Pre-DPF, common-rail-free simplicity
  • Huge touring/aftermarket support
  • Excellent tow vehicle

Cons

  • Timing belt is a scheduled service item - overdue belts are a real risk
  • Cracked cylinder heads are a known high-km / chipped / hard-towing failure
  • All are old now with very high km
  • Thirstier than the smaller modern diesels

Known problems

high
Cracked cylinder head
The 1HD-FTE head can crack between valve seats/injector bores, especially on chipped engines or those worked hard towing in heat - coolant loss and combustion gases in the cooling system are the tells.
Fix: Replacement head (often upgraded). Keep cooling system healthy and avoid over-aggressive tunes.
From 200k+ km (sooner if chipped/towed hard) · ~$3000-6000
high
Overdue timing belt
The cam timing belt must be replaced on schedule; a neglected belt risks valve damage.
Fix: Replace belt with tensioner/idlers on interval - confirm history before buying.
From ~100k km interval · ~$500-1000
medium
Injector and turbo wear
Injectors and the CT20B turbo wear at high km, causing smoke and lost power.
Fix: Diesel-specialist injector service; turbo rebuild/replacement.
From 200k+ km · ~$1500-3500

Gear-driven timing - extremely robust

Pros

  • Mechanically simple, gear-driven, near-indestructible
  • Live front axle (105) loved for remote/outback simplicity
  • Will run on poor fuel and minimal electronics
  • Very easy to repair anywhere

Cons

  • Genuinely slow - struggles loaded or in hills
  • Noisy and agricultural
  • Often aftermarket-turbo'd (verify install quality)

Known problems

medium
Overheating if cooling neglected (esp. aftermarket turbo)
The NA 1HZ runs cool and reliable; many are turbo'd aftermarket, which can cause head/cooling stress if done cheaply.
Fix: Verify any turbo install (intercooler, EGT/boost gauges); maintain cooling system.
From Any · ~$1000-3000
medium
Injector pump wear
Mechanical injection pump and injectors wear at very high km.
Fix: Diesel-specialist pump/injector rebuild.

Common problems (all variants)

medium
A442F 4-speed auto - towing overheat / wear
The 4-speed auto can overheat and wear when towing heavy without an aftermarket cooler, leading to harsh shifts or failure.
Fix: Fit a transmission cooler, service fluid regularly; valve body/rebuild if shifting poorly.
From 150k+ km · ~$1500-3500
low
Front wheel bearings / birfields
Front wheel bearings and (105 live-axle) birfields wear with km and off-road use.

From 150k+ km · ~$300-800
medium
Rust - rear quarters, tailgate, chassis (coastal)
Rust appears on rear arches, tailgate and chassis on coastal/hard-worked examples.
