Why the 1998 Ford Explorer Remains a Reliable Beast in 2026

The 1998 Ford Explorer occupies a unique space in automotive history. As we move deeper into 2026, many vehicles from the late 90s have succumbed to rust or mechanical obsolescence, yet this second-generation Explorer continues to show up on trails, job sites, and budget car lots. It was the peak of Ford’s dominance in the mid-size SUV market, and the engineering choices made for the 1998 model year—splitting the difference between rugged utility and daily comfort—have given it a longevity that many of its successors lacked.

Deciding to run a 28-year-old SUV as a daily driver or a weekend project requires a clear understanding of what made this specific year special. The 1998 model sat in the sweet spot of the second generation (1995–2001), benefiting from early refinements while avoiding the complex electronics and independent rear suspension issues that plagued the 2002 redesign.

The Engine Trinity: Choosing the Right Powerplant

In 1998, Ford offered three distinct engines, and your experience with a used Explorer today will largely depend on which one is under the hood.

The 4.0L OHV V6: The "Iron Duke"

For those prioritizing longevity over speed, the 4.0-liter Over Head Valve (OHV) V6 is the engine of choice. Producing 160 horsepower, it won’t win any drag races, but its cast-iron head and block design are legendary for reliability. In 2026, these engines are frequently found with over 300,000 miles on the clock. The simplicity of the pushrod design means fewer moving parts in the timing system compared to its SOHC sibling, making it the most forgiving option for a DIY mechanic on a budget.

The 4.0L SOHC V6: Modern Performance with a Catch

The Single Over Head Cam (SOHC) version of the 4.0L V6 was the high-output choice for 1998, pushing 205 horsepower. It transformed the Explorer from a sluggish utility vehicle into something capable of modern highway merging. However, this engine is known for its complex timing chain setup. There are chains in the front and back of the engine, and the plastic guides are prone to failure over decades of heat cycles. If you hear a "rattle" between 2,000 and 3,000 RPM on a cold start, the timing cassettes are likely failing—a labor-intensive repair that often exceeds the value of the vehicle in today's market.

The 5.0L V8: The Holy Grail

The 302-cubic-inch (5.0L) V8 is arguably the most desirable engine for the 1998 Ford Explorer. It’s the same basic block found in the Mustang of that era, adapted for truck duty. It produces 215 horsepower and significantly more torque than the V6s. More importantly, it was paired with the 4R70W transmission, which is much sturdier than the 5-speed units found in the V6 models. If you are looking for a vehicle to tow a small boat or a trailer in 2026, the V8 is the only logical choice.

Drivetrain Options: 4WD, AWD, or RWD?

The 1998 Ford Explorer offered three distinct ways to put power to the ground, and each has its own maintenance profile in the current year.

1. Control Trac 4WD (V6 models): This was a sophisticated system for the 90s. It features a "4WD Auto" mode that uses sensors to detect wheel slip and automatically engages the front axle. For 2026 owners, the most common failure point is the vacuum-actuated hubs or the transfer case shift motor. These are relatively easy to replace, but a non-functioning 4WD system is a major bargaining chip during a purchase.
2. All-Wheel Drive (V8 models): The V8 Explorer didn't use a traditional selectable 4WD. Instead, it used a full-time AWD system with a viscous coupling in the transfer case. It’s incredibly robust but results in slightly lower fuel economy. It’s the "set it and forget it" option for drivers in snow-heavy regions.
3. Rear-Wheel Drive (RWD): Common in southern states, the RWD versions are simpler and lighter. They offer the best fuel economy (around 19-20 MPG on the highway) and have fewer suspension components to wear out, making them ideal for urban commuters who don't need off-road capability.

Interior Durability and 90s Ergonomics

Inside the 1998 Explorer, you’ll find the quintessential late-90s Ford aesthetic: rounded plastic panels, chunky buttons, and surprisingly comfortable seats.

• The Eddie Bauer and Limited Trims: These were the luxury SUVs of their day. In 2026, finding one with intact leather is a challenge, but if the previous owner conditioned the hides, they remain incredibly supportive for long hauls. The Mach Audio systems, while dated, were high-quality and are often still functioning.
• The Sport (2-Door) vs. 4-Door: The 2-door Sport model has a shorter 101.7-inch wheelbase, making it easier to park but much harder to access the rear seats. The 4-door model (111.9-inch wheelbase) is the practical choice, offering 43.5 cubic feet of cargo space behind the second row. For a 2026 buyer, the 4-door's utility makes it a far more versatile tool for hauling gear or groceries.

Mechanical Realities: What to Watch For in 2026

Running a vehicle that is nearly three decades old requires realistic expectations. While the 1998 Ford Explorer is "built Ford tough," certain components have a finite lifespan.

The Transmission Struggle

The 5R55E 5-speed automatic transmission used in V6 models is the most common point of failure. Owners often report delayed engagement into reverse or slipping between second and third gear. In 2026, a transmission rebuild can cost as much as the car itself. Checking the fluid color and smell is non-negotiable; if the fluid is black or smells burnt, walk away.

Suspension and Chassis

The front suspension uses a torsion bar setup with upper and lower control arms. Over 28 years, the rubber bushings in these arms dry out and crack, leading to "clunking" noises over bumps and poor alignment. Ball joints are another high-wear item. Fortunately, because Ford sold millions of these vehicles, replacement parts remain cheap and widely available at any local auto parts store.

Rust and Corrosion

Depending on where the vehicle spent its life, rust can be a terminal issue. The rear wheel arches and the rocker panels are the first places to go. More importantly, inspect the frame rails near the rear leaf spring shackles. If the frame is compromised by scale or holes, the vehicle is unsafe and should be avoided regardless of how well the engine runs.

The 1998 Ford Explorer as a 2026 Project Car

One reason this vehicle has stayed popular is its massive aftermarket support. For those looking to build a budget overlander, the 1998 Explorer is a fantastic platform.

• Lift Kits: Simple torsion bar cranks and rear shackle replacements can provide a 2-inch lift for minimal cost.
• Tire Clearance: With minor trimming, these SUVs can fit 31-inch or even 32-inch all-terrain tires, significantly improving off-road prowess.
• Parts Interchangeability: Many parts from the Ford Ranger and the Mercury Mountaineer of the same era are direct swaps, making junkyard diving a productive way to maintain the vehicle.

Comparing the Trims: Which One to Buy?

If you are scanning the classifieds in 2026, here is how the 1998 lineup breaks down in terms of modern value:

Is it Safe by 2026 Standards?

Safety is the area where the 1998 Explorer shows its age most clearly. While it comes standard with dual front airbags and four-wheel ABS, it lacks the side-curtain airbags, stability control, and advanced crumple zones of modern vehicles. It also does not feature LATCH anchors for child seats, which was not mandated until later. For a solo driver or a couple, it provides a high seating position and a heavy steel frame, but it cannot compete with the active safety technology found in SUVs built in the last decade.

Why it Still Matters

In a world of increasingly complex, software-defined vehicles, the 1998 Ford Explorer is a breath of fresh air for those who enjoy mechanical simplicity. It is a vehicle that tells you exactly what is wrong with it through sounds and vibrations rather than cryptic dashboard codes.

Whether you need a "beater" to get through a harsh winter, a cheap entry point into off-roading, or a nostalgia-heavy cruiser from your youth, the '98 Explorer remains a viable candidate. As long as you prioritize the V8 engine or the OHV V6, and keep a close eye on the transmission and rust, this SUV still has plenty of miles left in it. It represents an era when cars were built to be used hard and fixed in a driveway—a philosophy that still resonates in 2026.
