The 1998 Toyota 4Runner is a midsize body-on-frame SUV known for its rugged build, real off-road capability, and long-term durability. It belongs to the third-generation 4Runner (1996–2002), a major redesign that improved ride comfort, safety, and refinement while keeping truck-like toughness. It’s ideal for drivers who want a dependable daily driver that can also handle towing, trails, snow, and weekend adventure gear. In the used SUV market, the 1998 4Runner is often sought after for its strong resale value and reputation for longevity when maintained.

- Engine choices: a 2.7L inline-4 (3RZ-FE) for simplicity and fuel economy, or the more popular 3.4L V6 (5VZ-FE) known for strong reliability and better power for hills, towing, and highway passing. - Available 4WD with a two-speed transfer case delivers true low-range capability, making it a practical SUV for dirt roads, camping access, and winter conditions. - Truck-based chassis and suspension tuning provide a solid blend of on-road comfort and off-road toughness compared to many crossover SUVs. - Practical utility: a tall cargo area, foldable rear seats, and a rear liftgate layout that works well for hauling tools, pets, and outdoor equipment. - Strong aftermarket and parts support, which makes it easier to find replacement components and upgrades for suspension, lighting, armor, and maintenance items.

Many owners consider the 1998 Toyota 4Runner reliability to be a standout, but age and mileage bring predictable wear points. Common 1998 Toyota 4Runner problems and issues include: 1) Valve cover gasket leaks (especially V6): Oil seepage onto the exhaust or engine block is common as gaskets harden with age, often showing up around 120,000–200,000 miles. It’s usually not catastrophic, but ignoring it can create smoke, odors, and messy buildup. 2) Timing belt service (V6) and related components: The 3.4L V6 uses a timing belt that should be replaced on schedule along with the water pump and idlers. Skipping this maintenance is one of the biggest risks on a used example, often becoming urgent around 90,000-mile intervals. While the 5VZ-FE is generally forgiving, neglected components can still fail and leave you stranded. 3) Lower ball joint wear and steering/suspension looseness: As mileage climbs (often 150,000+), owners report clunks, wandering steering, or uneven tire wear from worn ball joints, tie rods, and bushings. This is a safety-related area, so it’s worth addressing early. 4) Rust in frame and underbody (region-dependent): In snow/salt states, corrosion can be a major issue. Common trouble spots include frame rails, rear control arm mounts, and suspension brackets. Severe rust can be costly and can impact alignment and structural integrity.
