On the 1990-1999 Toyota Land Cruiser, in salt-belt and coastal climates, corrosion is the primary killer of these otherwise-durable trucks. The rear quarter panels are a notorious rot spot: the rear wheel-arch extension acts as a bucket that traps wet mud and road salt, and water intrusion past the rear side-window and tailgate seals (with no drain holes in the spot-welded section) rusts the panels from the inside out. Owners should also inspect the frame rails, body mounts, rocker panels, and wheel wells. Because mechanical parts commonly outlast the sheet metal and frame, rust condition is often the deciding factor in whether a 1990s Land Cruiser is worth restoring.
Bubbling/perforation at rear wheel-arch and quarter panels
Rusty rocker panels and body-mount areas
Flaking/scaling frame rails
Water/dampness in rear cargo area
How to Fix
Cut out and weld in replacement quarter-panel/rocker repair sections (reproduction doglegs and OEM-style panels are available), fix the water-intrusion source (reseal windows and tailgate), and treat/cavity-wax the frame. For surface frame rust, media-blast and coat; for perforated frame or body mounts, weld in new steel. Preventive rinsing of the rear arches and undercoating markedly slows progression.

On the 1990-1999 Toyota Land Cruiser, like most vehicles of the era, the Land Cruiser's factory radiator uses plastic end tanks crimped to an aluminum core. With age and heat cycling the plastic becomes brittle and cracks, and on these trucks the leak very commonly originates near the rectangular boss on the top tank where the part number is stamped. It affects both the 80-series and the early 100-series and often appears around 80,000-100,000 miles; owners frequently report the tank 'suddenly lets go' rather than showing a slow drip first, which risks an overheat that can then damage the head gasket. A failing fan clutch (another common 80-series item) compounds the overheat risk. This makes a proactive radiator replacement a common preventive step on any high-mileage example.
Visible crack/leak at top radiator tank near part-number boss
Coolant loss and low-coolant warnings
Steam from radiator area
How to Fix
Replace the radiator (OEM/Denso or a quality all-metal aftermarket unit), and refresh the thermostat, upper/lower hoses and coolant while access is open. Inspect the fan clutch at the same time. Given the head-gasket downstream risk, many owners replace the radiator preventively rather than waiting for the tank to split.

On the 1990-1997 Toyota Land Cruiser, the 80-series uses a solid front axle with full-time 4WD, so the front birfield (Birfield-type CV) joints and steering knuckles are under constant load and require periodic service that many owners skip. Toyota specifies repacking the birfields/knuckles roughly every ~90,000 miles (with knuckle grease/wheel-bearing intervals in between). When neglected, symptoms include clicking/knocking on tight turns, grease slung on the inside of the wheels, and leaking inner axle/knuckle seals that let gear oil and grease mix and escape. A common servicing error is pumping grease into the square check plug (a level-check plug only), which never reaches the actual joint. Fast-wearing or repeatedly leaking inner seals can also indicate a bent/warped front axle housing. A pre-April-1994 vs later drive-plate thickness change means early and late birfields are not freely interchangeable.
Common Symptoms
Clicking or knocking during tight low-speed turns
Grease flung onto inner wheel/tire
Gear oil / grease leaking from front knuckles
Front-end vibration or play
How to Fix
Perform a full front axle 'knuckle rebuild': disassemble the knuckles, clean and inspect birfields, install new inner axle seals, wiper (felt) seals, knuckle bearings and gaskets, and repack birfields and knuckles with the correct moly grease. Swapping birfields side-to-side extends their life since they wear on one side. Address a warped housing if seals wear abnormally fast, and use the correct-era birfields when replacing. Many owners DIY this; a shop rebuild of both sides is straightforward but labor-intensive.
