The most serious are 100 Series Frame Rust and Corrosion ($300-$8,000 repair), Front Lower Ball Joint Wear and Separation Risk (100 Series) ($300-$1,200 repair) and Timing Belt Tensioner and Water Pump Failure (2UZ-FE) ($1,000-$2,500 repair). The most commonly reported issue is 100 Series Frame Rust and Corrosion with 1,400 owner reports. Across all issues, repair costs range from $50 to $8,000. DIY maintenance guides at au7o.io.

All 6 Known Issues

On the 1998-2007 Toyota Land Cruiser, the 2UZ-FE 4.7L V8 uses a timing belt that must be replaced at 90,000-mile intervals. The hydraulic timing belt tensioner and idler pulleys are critical failure points — if the tensioner fails, the timing belt can slip or break, potentially causing valve-to-piston contact on this interference engine. The water pump is driven by the timing belt and commonly leaks at the same mileage interval. Since the labor to access the timing belt is 6-8 hours, all components (belt, tensioner, idler pulleys, water pump) should be replaced together as a comprehensive timing belt service.

This issue also affects: Buick Enclave, Buick Encore, Buick LaCrosse

Common Symptoms

Squealing or chirping noise from timing belt area
Coolant leak from water pump weep hole
Engine approaching or past 90,000 miles without timing belt service
Timing belt showing cracks or wear on inspection
Rough idle or engine timing issues

How to Fix

Perform a comprehensive timing belt service every 90,000 miles, replacing the timing belt, hydraulic tensioner, both idler pulleys, and water pump together. A complete timing belt kit with water pump costs $250-$500 for parts. Labor is 6-8 hours ($600-$1,200) due to the tight engine bay and need to remove accessories for access. Use OEM Toyota or Aisin (OEM supplier) components only — aftermarket timing belts and tensioners have higher failure rates on this engine. Always replace the thermostat and coolant while the system is apart. Total cost: $1,000-$1,800 at an independent shop, $1,500-$2,500 at the dealer.

NoteDo NOT skip or delay the 90,000-mile timing belt service. The 2UZ-FE is an interference engine — if the belt breaks, valves hit pistons and you are looking at a $5,000-$8,000 engine rebuild. This is the single most important maintenance item on the 100-series.
TipAlways replace the water pump with the timing belt. The pump costs $60-$100 extra and the labor is already done. A water pump failure between timing belt services means paying for the full labor again.

On the 1998-2007 Toyota Land Cruiser 2UZ-FE, the secondary air injection (AI) system on the 100-series Land Cruiser (1998-2007) with the 2UZ-FE 4.7L V8 is a notorious failure point, identical to the issue on the Sequoia and Tundra of the same era. The electric AI pump, air switching valves (ASV), and exhaust manifold check valves all fail. The aluminum check valves in the exhaust manifolds corrode and seize, the ASV sticks from carbon buildup, and the pump motor eventually burns out. This system is responsible for the most common check engine light on 100-series Land Cruisers.

This issue also affects: Toyota 4Runner, Toyota Tacoma, Lexus GX

Common Symptoms

Check engine light with air injection codes
Loud whirring from AI pump on cold start
AI pump not running on cold start (silence where there should be noise)
Multiple emissions-related fault codes
Failed emissions inspection

How to Fix

The complete repair involves replacing the AI pump ($300-$500), both ASV valves ($200-$400 each), and both exhaust manifold check valves ($100-$200 each). Total dealer cost: $1,500-$3,000. Many Land Cruiser owners in non-emissions states delete the entire AI system and install an ECU tune to suppress the codes ($300-$500 for the tune). In emissions states, the full repair is required. A common partial fix is to replace just the check valves and ASV, leaving the pump in place — the pump usually fails last.

On the 1998-2007 Toyota Land Cruiser, 100 Series Land Cruisers (J100) develop significant frame rust in salt-belt regions, particularly along the rear frame rails, crossmembers, and body mounts. Despite the vehicle's legendary reliability, frame corrosion is the primary structural concern for high-mileage examples.

Common Symptoms

Visible rust scale on frame rails
Body mount separation
Rear crossmember deterioration
Exhaust hangers breaking through rusted frame
Failed safety inspection

How to Fix

For early rust: sand to bare metal, treat with POR-15 or Eastwood Rust Encapsulator, and apply annual Fluid Film undercoating. Moderate rust requires welded reinforcement plates. Severe cases need professional frame-off restoration or donor frame swap. Due to rising 100 Series values ($20K-$60K+), frame restoration is often worthwhile.

On the 1998-2007 Toyota Land Cruiser, the 1998-2007 100 Series Land Cruiser (J100) develops lower ball joint wear, particularly on vehicles used for off-roading or carrying heavy loads. The sealed ball joints cannot be greased and wear out over time. Toyota does not sell the ball joints separately from the lower control arm (LCA), requiring aftermarket parts for standalone ball joint replacement. Worn ball joints cause clunking, steering wander, and uneven tire wear. Complete ball joint separation, while rare, is a critical safety concern that can cause loss of steering control. Regular inspection at every oil change is recommended for high-mileage 100 Series trucks.

Common Symptoms

Clunking noise from front end over bumps
Steering wander or imprecise feel
Uneven front tire wear (inner or outer edge)
Vehicle drifts or pulls under braking
Visible play when checking ball joints with vehicle jacked up
Popping sound when turning at low speed

On the 1998-2021 Toyota Land Cruiser, the center differential lock on the Land Cruiser uses an electric vacuum actuator to engage and disengage the locking mechanism. The actuator motor fails, the vacuum lines crack and leak, or the shift fork inside the transfer case wears, preventing the center diff lock from engaging or disengaging properly. A stuck center diff lock can leave the vehicle in permanently locked mode (causing binding and tire wear on pavement) or unable to lock (reducing off-road capability). The dashboard indicator light may flash or show incorrect lock status.

This issue also affects: Jeep Gladiator, Lexus GX, Lexus LX

Common Symptoms

Center diff lock will not engage when button is pressed
Center diff lock indicator light flashing or not illuminating
Diff lock engaged but will not disengage
Clicking noise from transfer case area when pressing lock button
Binding or hopping sensation in turns (stuck in locked mode)
Reduced off-road traction (unable to lock)

How to Fix

Diagnose by checking the vacuum lines to the actuator for cracks and leaks (replace cracked lines with silicone vacuum hose, $10-$20). If vacuum is reaching the actuator but the diff does not lock, the actuator motor has failed ($200-$500 for parts, $300-$500 labor). In some cases, the transfer case shift fork is worn and requires transfer case disassembly ($800-$1,500 labor). Test the center diff lock regularly (monthly) to keep the mechanism exercised — Land Cruisers that never use the diff lock are more prone to actuator seizure.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipExercise the center diff lock monthly — engage it on dirt or gravel at low speed, drive 50 feet, then disengage. Actuators that sit unused for years are far more likely to seize. Use it or lose it.

On the 1998-2007 Toyota Land Cruiser, the dashboard on 100-series Land Cruisers (1998-2007) develops extensive cracks from UV exposure and heat cycling, similar to the issue affecting other Toyota/Lexus models from this era. The top surface of the dashboard cracks and becomes sticky, particularly in hot climates. The cracking is widespread enough that finding a 100-series with an uncracked original dashboard is rare. The same issue affects the Lexus LX470, which shares the same dashboard. Toyota did not extend warranty coverage for Land Cruiser dashboards as they did for some other affected models.

This issue also affects: Acura TL, Chevrolet Suburban, Dodge Ram 1500

Common Symptoms

Deep cracks on dashboard top surface
Dashboard material sticky or tacky to touch
Cracking spreading from center to edges over time
Dashboard surface rough and deteriorating
Glare from cracked reflective dashboard surface

How to Fix

Dashboard replacement with a new OEM unit costs $2,000-$4,000 installed and is rarely worth the expense on these vehicles. The most popular solution is a Coverlay molded dashboard cover ($200-$350), which is a rigid ABS plastic overlay that covers the cracks and looks nearly factory. DashMat fabric covers ($50-$100) are a budget option. Some owners have had dashboards professionally recovered in leather or vinyl ($500-$1,500) at upholstery shops. Use a windshield sunshade when parked to slow further deterioration.
