Shoppers often search “1998 Lexus LX reliability” because these SUVs can be extremely long-lived, but age-related problems are common. Overall reliability is generally strong when service history is documented, yet there are a few “1998 Lexus LX problems” that show up repeatedly. 1) Head gasket and cooling system weaknesses: Some owners report head gasket failure, often preceded by overheating. Risk can increase on higher-mile examples (commonly well over 150,000 miles), especially if coolant changes were neglected or the vehicle was driven while running hot. Watch for coolant loss, white exhaust smoke, or unexplained overheating. 2) Oil leaks from seals and gaskets: Valve cover gasket leaks, front crank seals, and other age-related seepage are common on older inline-6 engines. Many LX 450s develop drips as miles climb past 120,000–200,000, and leaks can worsen if PCV components are clogged and crankcase pressure rises. 3) Front axle/steering wear and “knuckle” service needs: The solid front axle is tough, but it requires periodic maintenance. Leaking knuckle seals, worn wheel bearings, and CV/axle-related grease leakage can show up around 100,000+ miles depending on use. Symptoms include grease on the inside of the front wheels, steering looseness, or clicking/vibration. 4) Aging suspension and braking components: Bushings, shocks, and steering linkage parts can wear out and cause wandering, clunks, or uneven tire wear. Brake pulsation from warped rotors or sticking calipers can also appear on higher-mile vehicles, especially if it’s been used for towing or mountain driving.
