Why a 1998 Jeep XJ? The End of an Era’s Enduring Appeal

1998 Jeep XJ For Sale: Unearthing an Off-Road Icon

The Jeep Cherokee XJ, produced from 1984 to 2001, is often lauded as one of the most successful and influential SUV designs ever. The 1998 model year holds a special place, representing one of the last "pure" XJs before minor styling changes in the final years. It encapsulates the XJ’s core philosophy: a robust, unibody construction, excellent ground clearance, and the venerable 4.0-liter inline-six engine.

For many, the 1998 XJ is the sweet spot. It benefits from years of iterative improvements, boasting features like stronger axles, improved interior ergonomics, and updated electrical systems compared to earlier models, yet it retains the classic, boxy aesthetic and mechanical simplicity that define the XJ legend. Its straightforward design makes it incredibly easy to work on, with a massive aftermarket support network providing parts and upgrades for virtually any need. Whether you’re looking for a capable daily driver, a weekend trail rig, or a restoration project, the 1998 XJ offers a compelling package that continues to attract a passionate following. Its increasing rarity in good condition also means that well-maintained examples are beginning to appreciate in value, making it a potentially sound investment for the discerning buyer.

Key Features and Specifications of the 1998 XJ

Understanding the specifics of the 1998 Jeep XJ is crucial for any potential buyer. These vehicles were built with a focus on durability and capability, offering a range of powertrains and options designed to tackle diverse terrains.

• Engine: The heart of the 1998 XJ is almost universally the 4.0-liter AMC High Output (HO) inline-six engine. This legendary powerplant is renowned for its incredible torque, reliability, and longevity. Rated at 190 horsepower and 225 lb-ft of torque, it provides ample power for both highway cruising and off-road crawling. Its cast-iron block and simple design make it highly durable and relatively easy to maintain.
• Transmissions:
  
  • AW4 Automatic: The most common and highly regarded transmission is the Aisin-Warner AW4 4-speed automatic. Known for its robustness and smooth shifting, it’s a favorite among enthusiasts.
  • AX-15 Manual: A 5-speed manual transmission (AX-15) was also available, though it’s much rarer. Manual XJs are often sought after by those who prefer direct control and a more engaging driving experience, particularly for technical off-roading.
• Transfer Cases:
  
  • NP231 Command-Trac: This is a part-time 4WD system, meaning it should only be used in 4WD on loose or slippery surfaces. It offers 2WD, 4-High, and 4-Low. Most 1998 XJs will have this system.
  • NP242 Selec-Trac: This more advanced system offers 2WD, Full-Time 4WD (which can be used on paved roads), Part-Time 4WD, and 4-Low. The NP242 is often preferred for its versatility, especially in varying weather conditions.
• Axles:
  
  • Front: Dana 30 (high pinion) is standard and very capable for most applications.
  • Rear: You’ll typically find either a Dana 35 or a Chrysler 8.25. The Chrysler 8.25 is generally considered stronger and more desirable, especially if you plan on larger tires or heavy off-road use. Check for the shape of the differential cover to identify (the 8.25 has a flatter, octagon-like shape, while the Dana 35 is more oval).
• Body Styles: Available in both 2-door and 4-door configurations, with the 4-door being significantly more common.
• Trim Levels: Common trim levels included SE (base), Sport (popular, often with color-matched accents), Country (more upscale, faux wood trim), and Limited (top-tier, leather, more features).

What to Look For When Buying a 1998 XJ (Inspection Guide)

Buying an XJ, especially one over two decades old, requires a meticulous inspection. These vehicles are known for their resilience, but certain areas are prone to wear and tear.

1. Rust (The XJ’s Arch-Nemesis): This is the single most critical factor. The XJ’s unibody construction means that frame rust can be a death sentence.
   • Check: Rocker panels, floorboards (especially under the carpet), rear quarter panels (behind the wheels), front frame rails (under the engine), rear frame rails (near the leaf springs), and the areas around the fuel tank and exhaust. Surface rust is common and manageable, but deep, structural rust is a red flag.
2. Engine (4.0L I6):
   • Listen For: Ticking (lifters, exhaust manifold crack), knocking, or excessive rattling.
   • Check For: Oil leaks (rear main seal is notoriously leaky but not always critical, oil filter adapter o-rings), coolant leaks (water pump, radiator, heater core), signs of overheating (discolored coolant, warped cylinder head – check for bubbling in radiator when running).
   • Look At: Fluid levels and condition. Ask about maintenance history (oil changes, cooling system flushes).
3. Transmission & Transfer Case:
   • Automatic (AW4): Shifts should be smooth, without harsh jerks or excessive slipping. Fluid should be red and not smell burnt.
   • Manual (AX-15): Clutch should engage smoothly without slipping or chatter. Gears should shift without grinding.
   • Transfer Case (NP231/242): Test 2WD, 4-High, and 4-Low. It should engage cleanly without excessive clunking or grinding. Check for leaks around the seals.
4. Suspension and Steering:
   • Look For: Worn bushings (control arms, leaf springs), cracked coil springs, worn shocks (leaking, bouncy ride).
   • Test For: Play in the steering wheel (tie rod ends, drag link, ball joints, steering box). "Death Wobble" is a common XJ issue (violent shaking at speed), often caused by worn steering components, alignment issues, or improper lift installation. While fixable, it indicates neglected maintenance.
5. Brakes: Check for pulsating pedal (warped rotors), grinding noises (worn pads), or pulling to one side.
6. Electrical: Test all lights, windows, power locks, HVAC (heater and A/C), radio, and dashboard gauges.
7. Interior: Assess the condition of seats (tears, foam wear), headliner (sagging is common), dashboard (cracks are very common, especially in sunny climates), and carpets.
8. Documentation: Ask for service records, receipts for modifications, and a clean title. A pre-purchase inspection (PPI) by a trusted mechanic, ideally one familiar with Jeeps, is highly recommended.

Common Upgrades and Modifications for the 1998 XJ

One of the greatest appeals of the 1998 XJ is its mod-ability. The aftermarket is flooded with parts, allowing owners to tailor their vehicle for specific uses.

• Lift Kits: Ranging from mild 2-inch budget boosts for larger tires to extreme 6-inch long-arm suspensions for serious rock crawling. Common types include coil spacers, full spring replacements, and long-arm kits for improved articulation.
• Tires: Upgrading to larger, more aggressive all-terrain or mud-terrain tires is almost a rite of passage. Common sizes after a modest lift are 31-33 inches.
• Bumpers and Armor: Steel bumpers offer increased approach/departure angles and protection, often with winch mounts. Rock sliders protect the rocker panels, and skid plates shield vital underbody components.
• Axle Upgrades: While the Dana 30 front is strong, the Dana 35 rear is often replaced with a Ford 8.8, Dana 44, or Chrysler 8.25 (if not already present) for added strength, especially with larger tires and lockers.
• Gearing: For larger tires, re-gearing the axles (e.g., to 4.10, 4.56, or 4.88) is crucial to restore power, improve fuel economy, and reduce strain on the drivetrain.
• Lockers: Adding selectable or automatic lockers to the differentials significantly enhances off-road traction.
• Cooling System: Upgrading the radiator (to a 3-row aluminum), water pump, and fan clutch can help prevent overheating, a common XJ issue.
• Steering Upgrades: Heavy-duty tie rods, drag links, and steering boxes are popular to improve steering response and durability, especially with larger tires.

Pricing Your 1998 Jeep XJ: Factors Influencing Value

The price of a 1998 Jeep XJ can vary wildly, from a few hundred dollars for a rusty parts donor to well over $15,000 for a meticulously restored or highly modified example. Several factors play a significant role:

• Condition (The Dominant Factor): Rust-free examples in excellent mechanical and cosmetic condition command the highest prices. Vehicles with significant rust or major mechanical issues will be priced much lower.
• Mileage: Lower mileage generally means higher value, though a well-maintained high-mileage XJ can still be a great buy.
• Maintenance History: Comprehensive service records indicating regular maintenance and proactive repairs add significant value.
• Modifications: Quality, desirable modifications (e.g., professional lift, proper re-gearing, upgraded axles, clean interior/exterior) can increase value. Poorly executed or extreme modifications can detract.
• Location: XJs from dry, rust-free climates (Southwest, West Coast) typically fetch higher prices due to their superior body condition.
• Trim Level & Options: A 4.0L, NP242 transfer case, and certain trim levels (like Sport or Limited) might be slightly more desirable. A rare 2-door manual can also command a premium.
• Market Demand: The XJ market is strong, with demand often outpacing supply for clean examples.
