The Enduring Legacy of the XJ Cherokee: Why 1999 Stands Out

The Jeep Cherokee XJ is not just a vehicle; it’s a cultural icon. Its unibody construction, a pioneering feature at the time, offered a lighter yet rigid platform, contributing to its nimble handling both on and off the pavement. It carved out a unique niche between traditional body-on-frame SUVs and more car-like crossovers.

The 1999 model year holds a special place for several reasons:

• Peak of Refinement: By ’99, Jeep had nearly two decades to perfect the XJ platform. Most early quirks had been ironed out, and it received minor updates that enhanced usability without compromising its core character.
• Reliable Powertrain: It features the venerable 4.0-liter "PowerTech" inline-six engine, widely regarded as one of the most durable and reliable engines ever produced.
• No "Low Pinion" Dana 30: Unlike later 2000-2001 models which received a less desirable low-pinion Dana 30 front axle, the 1999 models retained the more robust high-pinion Dana 30, a significant advantage for serious off-roaders.



• Strong Aftermarket Support: Due to its popularity and longevity, the XJ benefits from an unparalleled aftermarket parts supply, making maintenance, repair, and modification incredibly straightforward and often affordable.

For these reasons, the 1999 Jeep Cherokee 4×4 is often considered the sweet spot for those seeking the ultimate XJ experience.

Why Choose a 1999 Jeep Cherokee 4×4? Key Benefits

Beyond its iconic status, the 1999 XJ offers a compelling set of practical advantages:

• Legendary Durability and Reliability: The 4.0L inline-six engine, paired with either the Aisin-Warner AW4 automatic or the Aisin AX-15 manual transmission (less common in ’99), is known for its ability to rack up hundreds of thousands of miles with proper maintenance. It’s a testament to robust engineering.
• Exceptional Off-Road Prowess: With its compact dimensions, excellent approach and departure angles, solid axles (Dana 30 front, Dana 35C or Dana 44 rear), and capable 4×4 systems (Command-Trac NP231 or Selec-Trac NP242), the XJ is a surprisingly potent off-roader straight from the factory.
• Simplicity and Ease of Maintenance: The XJ is a relatively simple vehicle, devoid of much of the complex electronics found in modern SUVs. This makes it a fantastic platform for DIY mechanics, saving significantly on labor costs. Parts are plentiful and inexpensive.
• Outstanding Value Proposition: Despite its capabilities, the 1999 Cherokee can be found at very affordable price points, making it an excellent entry point into the off-roading world or a reliable, budget-friendly daily driver. Its resale value tends to hold strong, especially for well-maintained examples.



• Unrivaled Customization Potential: The aftermarket support for the XJ is massive. From lift kits and larger tires to heavy-duty bumpers, rock sliders, and drivetrain upgrades, you can transform your XJ into anything from a mild overland rig to an extreme rock crawler.

What to Look For When Buying a 1999 Jeep Cherokee 4×4 (Inspection Guide)

Purchasing an older vehicle like an XJ requires a thorough inspection. Here’s a checklist of critical areas:

1. Rust, Rust, Rust: This is the XJ’s biggest enemy.
   • Unibody Frame Rails: Inspect the "frame" rails (they’re integrated into the unibody) from front to back, especially under the front seats and near the rear leaf spring mounts. Look for perforations, significant flaking, or previous patch jobs.
   • Floorboards: Check under the carpet for rust, particularly around the footwells and cargo area.
   • Rocker Panels: These are notorious for rusting out.
   • Rear Quarter Panels: Above and behind the rear wheels.
   • Doors & Hatch: Check bottoms of doors and around the rear hatch window for bubbling.
2. Engine (4.0L I6):
   • Leaks: Common areas include the rear main seal (RMS – usually drips, not a gush), oil filter adapter (OFA), valve cover, and power steering pump. Some minor weeping is normal for an older engine; significant leaks are a concern.
   • Cooling System: Check for a healthy radiator (no clogs or leaks), functional electric fan, good fan clutch (mechanical fan), and clear coolant. Overheating is a major issue for XJs.
   • Sounds: Listen for excessive valvetrain noise (tappets), knocking, or odd hums. A slight "tick" is often normal.
   • Maintenance Records: Ask for oil changes, coolant flushes, tune-ups.
3. Transmission & Transfer Case:
   • AW4 Automatic: Shifts should be smooth, not harsh or delayed. Check fluid color (red, not brown or burnt). Engage 4×4 modes; the transfer case lever should move cleanly, and the indicator light (if equipped) should function.
   • NP231/NP242: Ensure all 4×4 modes engage properly and that there are no grinding noises.
4. Suspension & Steering:
   • "Death Wobble": This is a violent, uncontrolled shaking of the front end, usually at highway speeds after hitting a bump. It’s caused by worn steering or suspension components (track bar, ball joints, tie rod ends, control arm bushings). Test drive on a bumpy road.
   • Bushings: Inspect control arm bushings, leaf spring bushings, and sway bar bushings for cracks or deterioration.
   • Shocks: Look for leaks.
   • Tires: Check for uneven wear patterns, which can indicate alignment issues or worn suspension.
5. Electrical System:
   • Test all lights, windows (especially power windows), wipers, radio, HVAC fan, and gauges. The XJ can have quirky electrical gremlins.
6. Interior:
   • Check for significant wear, tears, stains. Ensure all seat belts function. Look for signs of water intrusion (damp carpets, mildew smell).
7. Documentation:
   • Always verify the title is clear. Ask for service records; a well-documented XJ is a good sign.

Common Issues and Practical Solutions

Even a well-maintained 1999 XJ might exhibit some common characteristics or issues. Knowing them helps in diagnosis and repair:

• Rear Main Seal (RMS) and Oil Filter Adapter (OFA) Leaks: These are very common. The RMS is an involved fix, but the OFA is relatively easy (new O-rings). Don’t let a minor RMS leak be a deal-breaker if the price is right and the rest of the Jeep is solid.
• Cooling System Vulnerabilities: The XJ’s cooling system is marginal. Keep it properly maintained (clean radiator, good fan clutch, fresh coolant). Upgrading to a three-row radiator is a popular modification.
• "Death Wobble": As mentioned, diagnose and replace worn steering and suspension components. A quality adjustable track bar is often key.
• Crankshaft Position Sensor (CPS) Failures: Can cause intermittent stalling, no-start conditions, or rough idling. An easy part to replace.
• Sagging Leaf Springs: Over time, the rear leaf springs can flatten, causing a "squatted" appearance. Replacement or an "add-a-leaf" is a common fix.
• Window Motor Failures: Power window motors can fail, especially the driver’s side. Replacement is straightforward.

Owning and Maintaining Your 1999 XJ Cherokee

Once you’ve purchased your XJ, proactive maintenance is key to its longevity:

• Regular Fluid Changes: Engine oil, transmission fluid (AW4 is sensitive to old fluid), transfer case fluid, differential fluids, coolant, and power steering fluid.
• Grease U-joints: Regularly grease the driveshaft U-joints, especially if you drive off-road.
• Inspect Suspension Components: Periodically check ball joints, tie rod ends, and bushings for wear.
• Tire Rotation and Balance: Essential for tire longevity and preventing steering issues.
• Rust Prevention: Wash off road salt, repair paint chips, and consider applying rust inhibitors to the undercarriage.
• DIY Friendly: Embrace the XJ’s simplicity. Many repairs and maintenance tasks are well within the capabilities of a novice mechanic with basic tools and a service manual. Online forums (like NAXJA) are invaluable resources.

Customization and Upgrades: Making Your XJ Your Own

One of the greatest joys of owning an XJ is the ability to customize it. The aftermarket is vast!

• Lift Kits: Ranging from 2-inch budget boosts to 6.5-inch long-arm kits, lifts allow for larger tires and increased ground clearance.
• Tires: Larger, more aggressive all-terrain or mud-terrain tires dramatically improve off-road performance and aesthetics.
• Armor: Steel bumpers, rock sliders, and skid plates protect vital components during off-road excursions.
• Recovery Gear: Winches, high-lift jacks, and recovery straps are essential for serious off-roading.
• Drivetrain Upgrades: Stronger axles, lockers, and lower gearing can transform an XJ into an extreme trail machine.
