The Enduring Appeal of the 1999 Jeep XJ Cherokee
Why does a vehicle from 1999 continue to command such respect and demand? The answer lies in its fundamental design and legendary components. The 1999 XJ is celebrated for:
- The 4.0L AMC Inline-Six Engine: Widely regarded as one of the most reliable and durable engines ever produced, this powerhouse offers ample torque and a reputation for longevity, often exceeding 300,000 miles with proper maintenance. The 1999 model year benefits from a revised intake manifold that is less prone to cracking than earlier versions, and a coil-on-plug ignition system that improved reliability and performance.
- Solid Axles and Unibody Construction: Unlike many modern SUVs, the XJ retains solid front and rear axles (Dana 30 front, typically Dana 35 or the more desirable Chrysler 8.25 rear). This, combined with its robust unibody construction (often referred to as a "uni-frame"), provides exceptional off-road articulation and durability.
- Compact Size and Maneuverability: Its relatively compact footprint makes it highly maneuverable on trails and in urban environments, distinguishing it from larger, more cumbersome SUVs.
- Simplicity and Modifiability: The XJ’s straightforward design makes it relatively easy to work on, and the aftermarket support for modifications is immense. From lift kits and heavy-duty bumpers to drivetrain upgrades, owners can customize their XJ to suit almost any need.
- Timeless Design: Its boxy, purposeful lines have aged remarkably well, standing out in a sea of increasingly aerodynamic and indistinguishable SUVs.
The 1999 model year, in particular, is often considered the "sweet spot" by many enthusiasts due to its mechanical refinements before the transition to the Grand Cherokee (WJ) and Liberty (KJ) platforms.
What to Look for When Buying a 1999 Jeep XJ
Purchasing a 1999 Jeep XJ requires a meticulous inspection, as even the most robust vehicles can suffer from neglect or specific common issues. Here’s a detailed checklist:
1. Rust: The Silent Killer

This is often the most critical factor. The XJ’s unibody construction means structural rust can be a deal-breaker.
- Frame Rails: Inspect the "frame" rails (unibody subframe) especially where the control arms attach, under the doors, and around the leaf spring mounts.
- Floorboards: Check under the carpet for rot, especially near the front footwells and rear cargo area.
- Rocker Panels: These are highly susceptible to rust due to water and road salt exposure.
- Rear Quarter Panels: Often rust around the wheel wells and where the bumper mounts.
- Underbody Components: Check exhaust, fuel tank skid plate, and crossmembers.

2. Engine (4.0L I6): The Heartbeat
While reliable, the 4.0L isn’t immune to issues.
- Oil Leaks: Common culprits include the rear main seal, valve cover gasket, and oil filter adapter. Minor leaks are often tolerable, but significant drips indicate a need for repair.
- Coolant Leaks: Inspect the radiator, hoses, water pump, and thermostat housing. Look for signs of overheating (discolored coolant, steam, or history of gauge spikes).
- Rough Idle/Misfires: Could indicate faulty sensors (Crank Position Sensor is notorious), fuel delivery issues, or spark plugs/coil packs.
- "Ticking" Noise: Often lifter noise, sometimes minor and harmless, but can indicate low oil pressure or wear.
3. Transmission
- AW4 Automatic: This Aisin-Warner unit is incredibly durable. Check fluid color (should be red, not dark brown or black), smell (not burnt), and ensure smooth, timely shifts without slipping or harsh clunks.
- AX-15 Manual: Less common. Check clutch engagement, pedal feel, and listen for grinding or difficulty shifting.
4. Transfer Case
- NP231 (Command-Trac): Most common, part-time 4WD. Test all 4WD ranges (2H, 4H, 4L) for engagement and disengagement. Listen for excessive clunking.
- NP242 (Selec-Trac): Offers full-time 4WD (4FT). Similar checks, plus ensure the full-time mode works smoothly.
5. Axles and Driveline
- Differential Leaks: Check front (Dana 30) and rear (Dana 35 or Chrysler 8.25) differentials for fluid leaks around the covers and pinions.
- U-joints: Inspect drive shaft and axle shaft U-joints for play or clunking.
- Pinion Bearings: Listen for humming or whining noises, especially at highway speeds.
6. Suspension and Steering
- "Death Wobble": A violent shaking of the front end, typically above 45 mph. Often caused by worn steering components (tie rod ends, track bar, ball joints) or unbalanced tires.
- Sagging Leaf Springs: Common in the rear, leading to a "squatted" appearance.
- Shocks: Look for leaks or excessive bounce.
- Bushings: Inspect control arm and sway bar bushings for cracks or deterioration.
7. Interior and Electrical
- HVAC: Test heater, AC, and fan speeds.
- Power Windows/Locks: Common failure points.
- Gauges: Ensure all gauges (oil pressure, temp, fuel, volts) are functioning.
- Seat Condition: Check for tears, especially in the driver’s seat.
8. Modifications
- Quality Over Quantity: Well-installed, quality modifications (e.g., proper lift kit with adjustable components) can add value. Poorly installed, cheap, or excessive modifications can be a liability.
- Documentation: Ask for receipts for parts and professional installation.
Preparing Your 1999 Jeep XJ for Sale
For sellers, maximizing your XJ’s appeal and value requires strategic preparation.
1. Maintenance & Repairs
Address any known issues, especially those mentioned in the buyer’s guide. A well-maintained vehicle inspires confidence.
- Fluid Changes: Fresh oil, transmission fluid, coolant, and differential fluid are cheap ways to show care.
- Basic Tune-up: New spark plugs, air filter, and fuel filter.
- Fix Leaks: Even minor oil/coolant leaks can deter buyers.
- Safety First: Ensure brakes, tires, lights, and wipers are in good working order.
2. Cleaning & Detailing
First impressions are everything.
- Exterior: Wash, wax, clean wheels, and dress tires.
- Interior: Vacuum, wipe down surfaces, clean glass, and remove personal items. Consider shampooing carpets/seats.
- Engine Bay: A clean engine bay suggests a well-cared-for vehicle.
3. Documentation
Gather all relevant paperwork.
- Ensure it’s clear and in your name.
- Service Records: Prove regular maintenance.
- Modification Receipts: Show the quality and cost of upgrades.
- Owner’s Manual: A nice bonus for buyers.
4. Photography
High-quality photos are critical for online listings.
- Lighting: Shoot in good natural light, avoiding harsh shadows.
- Angles: Capture the front, rear, sides, interior (front and back seats, dashboard), engine bay, and undercarriage (if clean).
- Highlight Features: Show off any desirable modifications or unique aspects.
- Honesty: Don’t hide flaws, but present them clearly and explain them in the description.
5. Pricing Strategy
Research is key to setting a competitive price.

Navigating the Market: Tips for Buyers
1. Set a Realistic Budget
Beyond the purchase price, factor in potential immediate repairs, maintenance, and insurance. The XJ is affordable to buy, but a neglected one can quickly become a money pit.
2. Research Common Issues
Arm yourself with knowledge. Understand where rust typically forms, common engine leaks, and what "death wobble" entails.
3. Pre-Purchase Inspection (PPI)
If possible, have a trusted mechanic (especially one familiar with Jeeps) inspect the vehicle. This small investment can save you thousands.
4. Thorough Test Drive
- Cold Start: Listen for strange noises immediately after starting.
- Engine Performance: Check for smooth acceleration, no hesitation, or excessive smoke.
- Transmission: Ensure smooth shifts in all gears (automatic) or smooth clutch engagement (manual). Test 4WD modes.
- Brakes: Check for pull, pulsation, or excessive noise.
- Steering: Feel for looseness, wandering, or "death wobble" at highway speeds.
- Listen: Pay attention to any unusual noises (whines, clunks, rattles) from the drivetrain, suspension, or exhaust.
5. Vehicle History Report
A CarFax or AutoCheck report can reveal accident history, salvage titles, flood damage, or mileage discrepancies.
6. Negotiation
Be prepared to negotiate. Knowing the vehicle’s true condition and market value will give you leverage. Don’t be afraid to walk away if the deal doesn’t feel right.
7. Title and Registration
Ensure the seller has a clear title in their name and that all VINs match. Understand your local requirements for transferring ownership.
Common Modifications and Their Impact on Value
The XJ’s modifiability is a double-edged sword.
- Lift Kits: Quality lifts (e.g., from reputable brands like Old Man Emu, Rough Country, Rubicon Express) with proper geometry correction can add value. Cheap, poorly installed "spacer" lifts or those causing driveline angles can detract.
- Tires and Wheels: Aggressive tires and aftermarket wheels are popular. Ensure tires are in good condition and not excessively loud or worn.
- Bumpers and Armor: Steel bumpers, rock sliders, and skid plates enhance off-road capability and appearance.
- Engine Upgrades: Less common than suspension mods, but cold air intakes, exhaust systems, or performance tunes can slightly enhance value if done correctly.
- Interior Upgrades: Aftermarket stereo, upgraded seats, or added gauges can be a plus.
Well-executed, tasteful modifications that align with the XJ’s purpose (off-roading, overlanding) tend to add value or at least justify a higher asking price. However, extreme or poorly installed modifications can limit your buyer pool and potentially decrease value due to the perceived risk or cost of correction.
Challenges and Solutions
- Rust: The biggest challenge. Solutions range from localized patch panels for minor areas to full body swaps or major fabrication for severe cases. Prevention (undercoating, regular washing) is key.
- Parts Availability: Despite its age, parts for the XJ are generally excellent. OEM parts are often still available, and the aftermarket is robust, offering everything from common wear items to specialized off-road components. Online forums and specialty shops are great resources.
- Finding a "Good" One: It requires patience. The best XJs are often found through word-of-mouth, dedicated online communities, or enthusiast groups rather than traditional dealerships. Be prepared to travel.
- "Jeep Tax": Due to their popularity, some XJs are priced higher than their condition might warrant. Understand true market value and don’t overpay.
