The Enduring Appeal of the 1999 Jeep XJ
1999 Jeep XJ For Sale: Your Comprehensive Guide to Finding and Owning a Legend
Introduced in 1984, the Jeep Cherokee XJ quickly established itself as a groundbreaking vehicle. Its unibody construction, a significant departure from traditional body-on-frame SUVs of the era, offered a lighter, more agile, and surprisingly spacious package. Over its 18-year production run, the XJ garnered a reputation for reliability, off-road prowess, and a no-nonsense design.
The 1999 model year, in particular, is often considered the zenith of the XJ’s evolution. It retained the highly sought-after robust powertrain and solid axle setup while benefiting from minor refinements introduced over the years. Crucially, it was the last year before significant changes (such as the low-pinion Dana 30 front axle and a revised cylinder head that some enthusiasts consider less desirable, though still capable) were implemented for the 2000 and 2001 models. The 1999 XJ features the legendary 4.0-liter "Power Tech" inline-six engine, known for its bulletproof reliability and ample torque, paired with either the equally robust AW4 automatic transmission or the less common AX-15 manual. Its blend of simplicity, durability, and a vast aftermarket support network makes it a perpetual favorite among off-roaders and collectors alike.
Key Features and Specifications to Look For
When searching for a 1999 Jeep XJ for sale, understanding its core specifications will help you identify the right vehicle for your needs:
- Engine: The heart of the 1999 XJ is the 4.0L High Output (HO) Inline-6 cylinder engine. This naturally aspirated powerhouse delivers around 190 horsepower and 225 lb-ft of torque, renowned for its low-end grunt and longevity. Listen for smooth idling, consistent power delivery, and absence of excessive smoke.
- Transmission: Most 1999 XJs come with the Aisin-Warner AW4 4-speed automatic transmission. This unit is exceptionally durable and well-suited to the 4.0L engine. A small percentage were equipped with the Aisin AX-15 5-speed manual, which is highly desirable for enthusiasts seeking maximum control and engagement. Check for smooth shifts and proper engagement in all gears.
- Transfer Case: Two main transfer cases were available:
- NP231 Command-Trac: A part-time 4WD system, offering 2WD, 4-High Part-Time, Neutral, and 4-Low. It’s robust and ideal for serious off-roading.
- NP242 Selec-Trac: A full-time 4WD system, offering 2WD, 4-High Full-Time (for road use), 4-High Part-Time, Neutral, and 4-Low. This offers more versatility for varied driving conditions.
- Ensure the transfer case shifts cleanly into all positions.
- Axles:
- Front: All 1999 XJs came with a Dana 30 high-pinion front axle, known for its strength and widespread aftermarket support.
- Rear: The rear axle could be either a Dana 35 or, more desirably, a Chrysler 8.25-inch axle. The 8.25 is significantly stronger and more capable of handling larger tires and more aggressive off-roading without requiring immediate upgrades. You can identify the 8.25 by its flat bottom on the differential cover.
- Trim Levels: The 1999 XJ was available in various trim levels, including Sport, Classic, Limited, and Country.
- Sport: Often the most basic, but also the lightest and most common, making it a popular choice for modification.
- Classic/Limited/Country: Offered more creature comforts like power windows/locks, air conditioning, cruise control, leather seats, and upgraded interior trim. These can be nice for a daily driver but add complexity.
What to Look For When Buying a 1999 Jeep XJ: A Buyer’s Guide
Purchasing a vehicle that’s over two decades old requires careful inspection. Here’s a comprehensive checklist:
- Rust, Rust, Rust: This is the XJ’s Achilles’ heel. Thoroughly inspect:
- Rocker Panels: Look for bubbling paint, holes, or body filler.
- Floorboards: Check under the carpet for soft spots or holes.
- Frame Rails/Unibody Stiffeners: These are critical structural components. Look for rot, especially near suspension mounting points.
- Rear Quarter Panels: Prone to rust around the wheel wells and lower sections.
- Underbody: Examine the transmission crossmember and control arm mounts.
- Engine Health:
- Leaks: Common leaks include the rear main seal (often drips, not a major issue unless severe), oil filter adapter, valve cover, and power steering pump.
- Cooling System: Check the radiator, hoses, and water pump for leaks. Look for coolant sludge. The 4.0L can run hot, so a well-maintained cooling system is crucial.
- Sounds: Listen for knocks, ticks, or unusual noises.
- Exhaust: Check for exhaust manifold cracks (common, but repairable).
- Drivetrain:
- Transmission: Ensure smooth shifts (no hard jerks or slipping). Check fluid color (should be reddish, not burnt).
- Transfer Case: Shift through all 4WD modes. Listen for grinding or clunking.
- Driveshafts: Check U-joints for play.
- Axles: Listen for humming or clunking from the differentials.
- Suspension and Steering:
- "Death Wobble": A violent shaking of the front end at certain speeds. Indicates worn steering components (tie rod ends, drag link, track bar) or suspension bushings.
- Bushings: Inspect control arm bushings, sway bar bushings, and leaf spring bushings for cracks or wear.
- Shocks and Springs: Look for leaks on shocks and sagging springs.
- Electrical and Interior:
- Windows/Locks: Test all power accessories.
- HVAC: Ensure the heater and A/C work.
- Gauges: Check that all dashboard gauges function correctly.
- Headliner: Sagging headliners are common but repairable.
- Seats: Check for tears, especially on the driver’s side.
- Modifications: Many XJs have been modified. Evaluate the quality of modifications:
- Lift Kits: Are they reputable brands? Were they installed correctly? Look for proper geometry correction (e.g., control arm drop brackets, adjustable track bar).
- Tires: Are they excessively large for the lift?
- Welds: Inspect any custom fabrication for quality.
- Paperwork: Verify the title is clean. Ask for maintenance records if available.
Common Modifications and Upgrades
The 1999 XJ’s simple design and robust components make it an ideal platform for modification.
- Suspension Lifts: Ranging from 2-inch budget boosts for larger tires to 6+ inch long-arm systems for extreme articulation.
- Larger Tires: Often paired with lift kits for increased ground clearance and traction.
- Armor: Skid plates (engine, transmission, transfer case), rock sliders, and aftermarket bumpers protect critical components.
- Drivetrain Upgrades: Axle swaps (e.g., Ford 8.8, Dana 44), lockers (for improved traction), and re-gearing for larger tires.
- Cooling System Enhancements: Upgraded radiators, electric fans, and fan clutches are common to combat the 4.0L’s tendency to run warm, especially with heavy use.
- Steering Upgrades: Heavy-duty tie rods, steering boxes, and braces to prevent "death wobble" and improve durability.
Owning and Maintaining Your 1999 Jeep XJ
Owning a 1999 XJ is a rewarding experience, but like any classic vehicle, it requires consistent care.
- Routine Maintenance: Adhere to regular oil changes, fluid checks (transmission, transfer case, differentials), and grease critical components.
- Common Issues: Be prepared for the common XJ quirks:
- Rear Main Seal Leak: Almost all 4.0Ls leak. It’s often slow and manageable.
- Headliner Sag: A DIY repair with spray adhesive.
- Door Sag: Due to worn hinge pins, also a relatively easy fix.
- Cooling System: Be proactive. Flush the system, inspect the radiator, and consider upgrading the fan clutch or radiator if overheating is a concern.
- Aftermarket Support: One of the biggest advantages of the XJ is the unparalleled aftermarket support. Parts are readily available, often affordable, and there’s a wealth of knowledge online to guide you through repairs and upgrades.
- Community: The XJ has one of the most passionate and helpful online communities. Forums and social media groups are invaluable resources for advice, troubleshooting, and camaraderie.
