Why the 1998 Jeep XJ Stands Out: A Legacy of Capability

1998 Jeep XJ For Sale: Your Comprehensive Guide to Finding the Legendary Cherokee

The Jeep Cherokee XJ, produced from 1984 to 2001, revolutionized the SUV market. It was one of the first true unibody SUVs, blending the comfort and handling of a car with the off-road prowess of a traditional Jeep. The 1998 model year is particularly cherished for several key reasons:

• The Unkillable 4.0L Inline-Six Engine: Powering most 1998 XJs, the 4.0-liter "PowerTech" inline-six engine is legendary for its bulletproof reliability, ample low-end torque, and ease of maintenance. It’s a workhorse that, with proper care, can easily exceed 200,000 or even 300,000 miles.
• Robust Drivetrain Options: Paired with either the incredibly durable Aisin-Warner (AW4) automatic transmission or the capable Aisin AX15 manual, the 1998 XJ offered reliable power delivery. Transfer case options included the part-time NP231 (Command-Trac) for serious off-roading or the full-time NP242 (Selec-Trac) for added versatility on varied terrain.
• Solid Axles Front and Rear: Unlike many modern SUVs, the 1998 XJ retains solid axles (Dana 30 front, Dana 35 or Chrysler 8.25 rear), which are highly prized by off-roaders for their durability, articulation, and ease of modification.
• Refined but Rugged: By 1998, the XJ had undergone several refinements, including an updated interior with improved ergonomics and dual airbags, while retaining its fundamental ruggedness. It also featured OBD-II diagnostics, making troubleshooting easier than earlier models.
• Unmatched Aftermarket Support: Due to its immense popularity and long production run, the XJ boasts one of the most extensive aftermarket parts catalogs of any vehicle, allowing owners to customize, repair, and upgrade virtually every component.

These factors combine to make the 1998 Jeep XJ not just a vehicle, but a versatile platform capable of daily commuting, family hauling, and extreme off-road adventures, all while offering a distinct character that modern SUVs often lack.

Key Aspects to Consider When Buying a 1998 Jeep XJ

Purchasing a vehicle that is over two decades old requires a discerning eye. Here are the critical areas to scrutinize:

• 

  Rust: The XJ’s Arch-Nemesis: Being a unibody vehicle, rust is the single biggest killer of XJs. Pay meticulous attention to:

  • Frame Rails: Especially where the control arms attach.
  • Rocker Panels: Often rusted through, hidden by plastic cladding.
  • Floorboards: Check under the carpet for soft spots or holes.

  

  • Rear Quarter Panels: Prone to rust around the wheel wells and lower sections.
  • Under the Battery Tray: Common rust spot.
  • Rear Hatch and Door Sills: Check for bubbling paint or perforations.
  • A little surface rust is acceptable, but significant structural rust means walking away or preparing for extensive, costly repairs.

• The 4.0L Engine: While robust, it has common quirks:

  • Rear Main Seal (RMS) Leak: Often referred to as "dinosaur pee," this is a very common oil leak. It’s not usually catastrophic but can be messy and costly to fix if done professionally.
  • Valve Cover Gasket Leak: Another common, relatively easy fix.
  • Cooling System: XJs can run hot. Check the radiator, water pump, thermostat, fan clutch, and hoses for signs of leaks or deterioration. Ensure the electric fan kicks on.
  • Exhaust Manifold Cracks: Can lead to ticking noises, especially on cold start.
  • Listen for unusual noises, check for smoke from the exhaust (blue for oil, white for coolant, black for rich fuel).

• Transmission & Transfer Case:

  • AW4 Automatic: Check fluid color (should be red, not dark or burnt), listen for harsh shifts, delayed engagement, or slippage.
  • AX15 Manual: Check clutch feel, smooth shifting, and any grinding noises.
  • Transfer Case: Ensure 4WD engages smoothly in all settings (2WD, 4-High, 4-Low for NP231; add Full-Time for NP242). Listen for clunks or grinding. Check for leaks around the output shafts.

• Axles & Driveline:

  • Check for leaks at the differential covers and pinion seals.
  • Listen for humming or whining noises, especially at highway speeds, which could indicate worn differential bearings.
  • Inspect U-joints on the driveshafts for play or rust.
  • If it has a Dana 35 rear axle, be aware it’s weaker than the Chrysler 8.25, especially if larger tires are installed.

• Suspension & Steering:

  • Sagging Leaf Springs: Common in the rear, leading to a "squatted" appearance.
  • Worn Bushings: Listen for clunks or squeaks over bumps.
  • Steering Play: Excessive play in the steering wheel could indicate worn tie rod ends, ball joints, or a loose steering box.
  • Check for worn shocks and control arms.

• Electrical System & Interior:

  • Test all power windows, locks, mirrors, radio, HVAC blower, and gauges. XJs are known for occasional minor electrical gremlins.
  • Check the condition of seats (often torn), headliner (often sagging), and dashboard (prone to cracking).

Inspecting a 1998 XJ For Sale: A Step-by-Step Guide

1. Pre-Inspection Inquiry: Before you even see the Jeep, ask the seller detailed questions:

   • Why are they selling it?
   • What maintenance has been done recently (with records)?
   • Any accidents or major repairs?
   • Are there any known issues (be specific about leaks, noises, electrical problems)?
   • Has it been off-roaded heavily? What modifications have been made?

2. Exterior Walkaround:

   • Look for consistent paint color and panel gaps, indicating no major bodywork.
   • Check for rust as detailed above, paying extra attention to hidden areas.
   • Inspect tires for even wear (indicates good alignment and suspension) and tread depth.

3. Under the Hood:

   • Check all fluid levels (oil, coolant, power steering, brake fluid). Look for proper color and consistency.
   • Look for any signs of active leaks (oil, coolant, power steering fluid).
   • Inspect belts, hoses, and wiring for cracks, fraying, or chew marks.
   • Check the battery terminals for corrosion.

4. Underneath the Vehicle:

   • This is where a flashlight and a creeper are invaluable.
   • Thoroughly inspect the unibody frame rails, control arm mounts, and crossmembers for rust or damage.
   • Check differential covers, transfer case, and transmission pan for leaks.
   • Inspect exhaust system for rust holes or leaks.
   • Look at the condition of suspension components, driveshafts, and steering linkages.

5. Interior Check:

   • Sit in all seats, check seatbelts.
   • Test every button, switch, and knob. Turn on the AC/heat, fan speeds.
   • Check for dampness under the carpets, which could indicate leaks.
   • Verify all lights (dash, dome, exterior) work.

6. Test Drive:

   • Cold Start: Listen for engine noises (ticking, knocking), ensure no excessive smoke.
   • Engine Performance: Accelerate smoothly, check for hesitation, misfires, or loss of power.
   • Transmission: Feel for smooth shifts (automatic) or easy gear engagement (manual). Test all gears.
   • Brakes: Test stopping power, listen for grinding or squealing. Ensure it stops straight without pulling.
   • Steering: Check for excessive play in the wheel. Does it track straight or wander?
   • Suspension: Drive over bumps and uneven surfaces. Listen for clunks, squeaks, or excessive bounciness.
   • 4WD Engagement: Find a safe, low-traction area (dirt/gravel) to test 4-High and 4-Low. Ensure they engage and disengage properly. Listen for binding or unusual noises.

7. Pre-Purchase Inspection (PPI): Regardless of your mechanical aptitude, always invest in a professional pre-purchase inspection by a trusted mechanic, preferably one familiar with Jeeps and 4x4s. They can identify issues you might miss and provide an objective assessment of the vehicle’s condition.

Common Modifications and Their Impact

Many 1998 XJs have been modified, and understanding these changes is crucial:

• Lift Kits: Common for off-roading. Inspect the quality of the lift. A poorly installed lift can cause driveline vibrations, premature wear on components, and poor handling. Look for adjustable control arms, proper length shocks, and a slip-yoke eliminator (SYE) kit if the lift is significant.
• Larger Tires: Often accompany lift kits. Ensure the gearing is appropriate for the tire size; otherwise, performance and fuel economy will suffer. Check for rubbing on fenders during turns or articulation.
• Aftermarket Bumpers/Armor: Adds protection and a rugged look but also weight. Ensure the suspension has been upgraded to compensate.
• Engine Performance Mods: Less common but can include intake/exhaust systems or tuning. Generally, the 4.0L benefits little from simple bolt-ons.
• Axle Swaps/Lockers: Indicates a serious off-road build. Research the axles used and the quality of the work.

Owning a 1998 XJ: Challenges and Solutions

• Fuel Economy: The 4.0L isn’t known for its efficiency (expect 15-20 MPG). Solution: Accept it or consider a smaller, more modern vehicle if fuel costs are a primary concern.
• Age-Related Wear and Tear: Parts will wear out. Solution: The XJ is incredibly DIY-friendly, parts are cheap and abundant, and there’s a vast online community for support.
• Rust (Ongoing Battle): Even if you buy a rust-free example, prevention is key. Solution: Regular washing, especially in winter, applying rust inhibitors/undercoating, and addressing any new spots immediately.
• Interior Comfort: It’s basic and functional, not luxurious. Solution: Aftermarket seats, sound deadening, and updated stereo can improve the experience.
• Finding a Stock Example: Many have been modified. Solution: Be open to minor modifications, or be prepared to pay a premium for a truly unmolested XJ.
