The 1998 Ford Explorer stands as a definitive marker in the evolution of the American SUV. In an era where the market was transitioning from rugged, truck-based utility to family-oriented comfort, this model year captured a unique middle ground. Decades after its initial release, the 1998 Explorer remains a common sight on secondary markets, often serving as a testament to Ford’s late-90s engineering philosophy. Understanding whether this vehicle remains a viable option today requires a deep dive into its mechanical variations, historical pain points, and its standing in a modern automotive landscape.

The Engine Lineup: A Tale of Three Powerplants

One of the most critical aspects of the 1998 Ford Explorer is the diversity of its engine options. Ford offered three distinct powerplants, each catering to different types of drivers and utility requirements. Choosing the right one back then dictated the vehicle's longevity, and today, it dictates the maintenance schedule.

The 4.0L OHV V6

The base engine for many trims was the 4.0-liter Over Head Valve (OHV) V6. Producing approximately 160 horsepower and 225 lb-ft of torque, this engine was not a speed demon. It was a "old school" design, often referred to as the Cologne V6. Its primary advantage is simplicity. Without the complex overhead cam timing systems found in later engines, the OHV version is often cited as the most durable of the V6 options for high-mileage use. However, its fuel economy is modest, typically averaging around 15-17 mpg combined.

The 4.0L SOHC V6

Introduced to provide more competitive performance against Japanese rivals, the Single Over Head Cam (SOHC) version of the 4.0L V6 boosted output to 205 horsepower. This engine transformed the Explorer’s driving dynamics, making highway passing and towing significantly easier. However, this performance came with a trade-off. The SOHC engine is notorious for its complex timing chain arrangement, featuring cassettes and tensioners that can fail over time. When these components wear out, they produce a distinct "death rattle." In 2026, finding an SOHC model that has had its timing chain service completed is a top priority for any potential owner.

The 5.0L (302) V8

For many enthusiasts, the 5.0-liter V8 is the holy grail of the 1998 Explorer lineup. Derived from the legendary Mustang engine, this V8 produces 215 horsepower and a robust 288 lb-ft of torque. While the horsepower numbers seem close to the SOHC V6, the V8 offers superior low-end grunt and a much simpler mechanical design. It is widely considered the most reliable engine Ford ever put in the Explorer. The downside is the fuel thirsty nature of the block, often struggling to break 14 mpg in city driving.

Trim Levels and Body Styles: Sport vs. Four-Door

The 1998 model year was notable for its distinct body styles. The two-door "Explorer Sport" was aimed at a younger demographic or those who didn't require frequent rear-seat access. With a shorter wheelbase of 101.7 inches, it was more maneuverable in urban environments and slightly more capable in mild off-road scenarios.

The four-door models, spanning the XL, XLT, Eddie Bauer, and Limited trims, utilized a 111.5-inch wheelbase. This configuration provided the classic SUV utility that families craved, offering up to 81.6 cubic feet of cargo space when the rear seats were folded.

  • XL/XLT: These were the workhorses. Often found with cloth seats and basic amenities, they focused on utility.
  • Eddie Bauer: This trim added a touch of outdoor luxury, featuring two-tone paint schemes and high-quality leather interiors.
  • Limited: The flagship trim, providing automatic climate control, premium audio systems, and often the V8 engine as standard or a highly recommended option.

Driving Dynamics and Drivetrains

Handling in a 1998 Explorer is a reminder of the vehicle's truck-based roots. It utilizes a body-on-frame construction with a short-and-long-arm front suspension and a leaf-spring rear. While it doesn't offer the car-like ride of a modern crossover, it provides a sense of sturdiness.

The drivetrain options were equally varied:

  1. Rear-Wheel Drive (RWD): Common in warmer climates, offering the best fuel efficiency and simplest maintenance.
  2. ControlTrac 4WD: A sophisticated system for its time, featuring a dashboard dial that allowed drivers to switch between "Auto," "4WD High," and "4WD Low." In "Auto" mode, the system monitors wheel slip and sends power to the front wheels only when needed.
  3. All-Wheel Drive (AWD): Exclusive to the V8 models, this was a full-time system with no low-range gearing, optimized for on-road traction in rain or snow rather than rock crawling.

Living with a '98 Explorer in 2026

As of April 2026, the 1998 Ford Explorer has officially entered the "modern classic" or "high-mileage survivor" category. While the initial MSRP ranged from $19,880 to over $33,000, current resale values have stabilized significantly. A well-maintained unit might command a small premium for nostalgia, but most "good" condition vehicles trade for under $1,500.

Reliability Realities

Maintenance is the defining factor for any vehicle approaching three decades on the road. The 1998 Explorer has several well-documented areas that require inspection:

  • Transmission: The 5R55E automatic transmission paired with the V6 engines is a known weak point. Owners frequently report issues with the valve body or torque converter. In contrast, the 4R70W transmission paired with the V8 is much more robust.
  • Rust: In the "snow belt," the Explorer’s frame and rocker panels are susceptible to corrosion. Inspecting the mounting points for the leaf springs and the radiator support is essential.
  • Suspension Wear: Ball joints, tie rod ends, and sway bar links on these vehicles tend to wear out every 60,000 to 80,000 miles. A "clunking" sound over bumps is a telltale sign that a refresh is needed.
  • Secondary Hood Latch: A historical recall noted that the secondary latch could corrode and stick. It is a safety-critical item that should be lubricated or replaced if it shows signs of resistance.

Fuel Economy and Safety Standards

By modern standards, the 1998 Explorer is not an efficient vehicle. With a combined 14-17 MPG, it is expensive to operate as a daily driver in 2026. However, for occasional utility use or as a secondary "beater" vehicle, the cost of entry is low enough to offset the fuel prices for some.

Safety-wise, the 1998 model was a leader for its time, featuring standard dual front airbags and four-wheel anti-lock brakes (ABS). However, it lacks the side-curtain airbags, stability control, and advanced driver assistance systems (ADAS) found in vehicles manufactured in the last decade. The roof strength and side-impact protection also reflect the standards of the late 90s, not today’s more rigorous requirements.

The Enthusiast Perspective: Restoration and Mods

There is a growing community of enthusiasts who appreciate the second-generation Explorer for its simplicity. Unlike modern vehicles with integrated touchscreens and complex CAN-bus electrical systems, the '98 Explorer is relatively easy to work on for a DIY mechanic. Parts remain plentiful and inexpensive, thanks to the millions of units sold and the shared architecture with the Ford Ranger of the same era.

Common modifications include:

  • Mild Lifts: 1-2 inch torsion bar crank and rear shackle lifts to accommodate larger all-terrain tires.
  • Head Unit Upgrades: Replacing the factory cassette or CD player with a modern double-DIN unit with smartphone integration is a popular way to modernize the cabin.
  • Lighting: Replacing aged, yellowed halogen housings with clear lenses and LED bulbs significantly improves night visibility.

Common Recalls to Verify

If you are evaluating a 1998 Ford Explorer for purchase, checking the VIN for completed recall work is vital. Key recalls for this era included:

  • Speed Control Deactivation Switch (SCDS): A major fire hazard where the switch could leak internally and overheat. Ensure the fused harness or updated switch has been installed.
  • Throttle Body: Some 4.0L SOHC engines had throttle bodies that could stick due to deposit buildup, requiring additional force to break free.
  • Firestone Tires: While almost all of the original Firestone Wilderness AT tires are long gone from service due to age, the historical context of the tire-related rollovers remains a part of this vehicle's legacy. Ensure current tires are no more than six years old, regardless of tread depth.

Final Verdict: Is it Worth the Investment?

The 1998 Ford Explorer is a survivor. It represents a period when SUVs were transitioning from tools to toys. For a buyer in 2026, it offers a paradoxical value proposition. It is a vehicle with low acquisition costs but potentially high maintenance requirements if the previous owner neglected basic systems.

For those needing a heavy-duty towing vehicle or a refined highway cruiser, a newer model is likely a better fit. However, for someone seeking a simple, mechanical connection to the road, or a budget-friendly 4x4 for weekend camping trips, the '98 Explorer—specifically the V8 or the OHV V6 models—remains a viable candidate. Its longevity is not a matter of chance; it is a result of a robust, albeit dated, design that responds well to consistent care.

When inspecting one today, focus on the frame integrity and transmission shift quality. If those two components are solid, the rest of the vehicle can usually be kept running with basic tools and a modest parts budget. The 1998 Ford Explorer isn't just a relic of the past; it is a functional piece of automotive history that continues to earn its place on the road.
