Used 2004 Jeep Wrangler Unlimited For Sale: Your Comprehensive Buyer’s Guide

I. Why the 2004 Jeep Wrangler Unlimited (LJ) Stands Out

When you encounter a Used 2004 Jeep Wrangler Unlimited For Sale, you’re looking at more than just a standard Wrangler. This model year marked the debut of the Unlimited variant, offering significant advantages over its shorter-wheelbase sibling, the TJ.

The "LJ" Distinction:
The 2004 Wrangler Unlimited is built on a stretched version of the TJ platform. While the standard TJ had a 93.4-inch wheelbase, the LJ boasts an impressive 103.4-inch wheelbase – a full 10 inches longer. This seemingly minor difference translates into substantial improvements in several key areas, making the Used 2004 Jeep Wrangler Unlimited For Sale a highly sought-after commodity.

Key Features & Advantages:

• Increased Cargo Space: The primary benefit of the extended wheelbase is the significant boost in cargo capacity. The LJ offers 13 inches more cargo space behind the rear seat compared to the standard TJ, transforming it from a somewhat cramped two-seater (with the rear seat up) into a genuinely practical adventure vehicle capable of hauling more gear for camping, trail riding, or daily errands.
• Enhanced Rear Passenger Comfort: Those extra 10 inches aren’t just for cargo; they also provide an additional 2 inches of rear legroom, making the back seat much more accommodating for adult passengers on longer trips.



• Improved Ride Quality: The longer wheelbase inherently provides a smoother, more stable ride on pavement. This reduces the "choppiness" often associated with short-wheelbase vehicles, making the Used 2004 Jeep Wrangler Unlimited For Sale a more comfortable daily driver.
• Higher Towing Capacity: The LJ’s longer wheelbase and slightly increased curb weight contribute to a significantly higher towing capacity, rated at 3,500 pounds, compared to the standard TJ’s 2,000 pounds. This is a considerable advantage for those looking to tow small trailers, ATVs, or even a compact camper.
• Retained Off-Road Prowess: Despite the added length, the LJ retains the legendary off-road capability of the TJ. Its approach and departure angles remain excellent, and the solid front and rear axles (Dana 30 front, Dana 35 rear as standard, or the more desirable Dana 44 rear on some models) provide robust performance on challenging terrain. The 4.0L I6 engine and robust drivetrain components ensure it can conquer almost any obstacle.
• The Legendary 4.0L Inline-Six Engine: The 2004 LJ comes standard with Jeep’s venerable 4.0-liter PowerTech inline-six engine. Known for its torque, durability, and relatively simple design, this engine is a workhorse that has powered countless Jeeps through millions of miles. It’s a major selling point for any Used 2004 Jeep Wrangler Unlimited For Sale.
• Limited Production Charm: The 2004 model year was the first for the LJ, adding a touch of historical significance. The Unlimited was produced for only a few years (2004-2006), making LJs somewhat rarer and often holding their value better than standard TJs.

II. What to Look For: Key Inspection Points When Buying Used

Purchasing any used vehicle requires diligence, but a Used 2004 Jeep Wrangler Unlimited For Sale demands extra scrutiny due to its age and common use in challenging environments. A thorough inspection is paramount.

• Rust (The Silent Killer): This is the number one concern for any TJ/LJ. Inspect the frame meticulously, paying close attention to:
  • Skid plates: Often trap moisture and dirt, leading to frame rust underneath.
  • Control arm mounts: Common failure points where rust can compromise structural integrity.
  • Rear bumper mounts and crossmember: Prone to rust, especially if exposed to road salt or moisture.
  • Body: Check fenders (especially inner fenders), rocker panels, floor pans (under the carpet), and the tailgate. Surface rust is common; severe, flaky, or perforated rust is a deal-breaker.
• Engine (4.0L I6):
  • Oil Leaks: Common areas include the rear main seal (a notorious TJ/LJ leak, often minor but worth noting), valve cover gasket, and oil pan gasket. Look for fresh oil stains underneath.
  • Cooling System: Check the radiator for leaks or corrosion, inspect hoses for cracks, and ensure the coolant reservoir is at the correct level and the fluid is clean. Overheating can be a major issue.
  • Engine Sounds: Listen for knocking, ticking, or excessive lifter noise. A smooth idle and strong acceleration are good signs.
  • Check Engine Light: If illuminated, insist on scanning for codes with an OBD-II reader.
• Transmission (Automatic 42RLE or Manual NV3550):
  • Automatic (42RLE): Check fluid level and color (should be reddish, not dark or burnt-smelling). Test all gears, including reverse, for smooth, timely shifts without slipping or harshness.
  • Manual (NV3550): Test the clutch for proper engagement (no slipping), listen for grinding when shifting, and ensure all gears engage smoothly.
  • Fluid Leaks: Inspect the transmission pan and bell housing for leaks.
• Transfer Case (NP231):
  • Engage 4-High and 4-Low. The transfer case should shift smoothly and without binding or excessive clunking. Test it in a safe, unpaved area.
  • Check for leaks around the seals.
  • Inspect the linkage for excessive play or damage.
• Axles & Driveshafts:
  • Differential Leaks: Look for fluid seeping from the differential covers or pinion seals.
  • U-Joints: Inspect the universal joints on both driveshafts. Worn U-joints will often click or clunk when accelerating from a stop or shifting gears.
  • Wheel Bearings: Lift each wheel and try to wiggle it top-to-bottom and side-to-side. Excessive play indicates worn wheel bearings.
• Suspension & Steering:
  • Lift Kits: Many LJs are lifted. Assess the quality of the lift kit installation. Poorly installed lifts can lead to handling issues and premature wear.
  • Bushings: Inspect control arm bushings, sway bar bushings, and track bar bushings for cracks or deterioration.
  • Ball Joints & Tie Rod Ends: Check for play in these critical steering components.
  • Steering Box: Look for fluid leaks or excessive play in the steering wheel.
  • "Death Wobble" Potential: While not exclusive to Jeeps, TJs/LJs can experience a violent, uncontrollable shimmy in the front end known as "death wobble" when certain suspension/steering components are worn. A test drive on rough pavement can sometimes reveal this.
• Electrical System: Test all lights (interior and exterior), wipers, power windows (if equipped), horn, radio, and HVAC system (AC and heater).
• Interior: Check for torn seats, worn carpet, and functionality of all gauges. Pay attention to signs of water leaks (damp carpets, mildew smell), which can occur with both soft and hard tops.
• Modifications: Many Jeeps are modified. Assess the quality and purpose of any aftermarket parts (e.g., bumpers, winches, oversized tires, performance upgrades). Poorly executed modifications can cause more problems than they solve.

III. The Ownership Experience: Pros and Cons

Owning a Used 2004 Jeep Wrangler Unlimited For Sale is a unique experience. It’s not for everyone, but for those who embrace its quirks, it offers unparalleled adventure and a strong sense of community.

Pros:

• Iconic Style & Classic Jeep Feel: The LJ embodies the quintessential Jeep aesthetic – rugged, timeless, and instantly recognizable.
• Legendary Off-Road Capability: It’s built for trails, and with proper tires and perhaps a mild lift, it can tackle challenging terrain with ease.
• Strong Aftermarket Support: The TJ/LJ platform has one of the most extensive aftermarket parts selections, allowing for endless customization and upgrades.
• Relatively Simple Mechanics: Compared to modern vehicles, the LJ is less complex, making many repairs and maintenance tasks accessible to the DIY mechanic.
• Excellent Resale Value: LJs, particularly well-maintained ones, tend to hold their value exceptionally well due to their desirability and limited production.
• Open-Air Driving: The removable hardtop or fold-down soft top, along with removable doors and a fold-down windshield, offers an unparalleled open-air driving experience.
• Unique LJ Space Advantage: The added cargo and passenger space truly set it apart from the standard TJ.

Cons:

• Fuel Economy: Don’t expect great mileage. The 4.0L engine, combined with a relatively heavy and unaerodynamic body, typically delivers mid-to-high teens MPG.
• On-Road Comfort: While better than the standard TJ, it’s still a Jeep. The ride can be firm, and road noise (especially with a soft top or knobby tires) is noticeable. It’s not a luxury cruiser.
• Safety Features: As a 2004 model, it lacks many modern safety features like advanced airbags, stability control, or blind-spot monitoring.
• Maintenance: It’s an older vehicle. Expect regular maintenance and occasional repairs. Parts are available, but labor costs can add up if you don’t do your own work.
• Security: With a soft top, security is less robust than a hardtop or a typical car.
• Rust Susceptibility: As mentioned, rust is a significant concern, especially in regions with road salt or high humidity.

IV. Pricing & Valuation: What to Expect

The price of a Used 2004 Jeep Wrangler Unlimited For Sale can vary significantly based on several factors. These LJs command a premium over standard TJs due to their rarity and increased practicality.

Factors Influencing Price:

• Condition: This is paramount. A rust-free, well-maintained LJ will fetch a much higher price than one with significant rust or mechanical issues.
• Mileage: Lower mileage typically translates to higher value, though proper maintenance history can mitigate the impact of higher miles on a 4.0L engine.
• Maintenance History: Comprehensive service records are a huge plus.
• Hardtop vs. Soft Top: LJs with factory hardtops often command a higher price due to better security, noise reduction, and weather protection.
• Transmission Type: Both manual (NV3550) and automatic (42RLE) transmissions were offered. Preference varies, but often the manual can be slightly more desirable for off-roading purists.
• Axle Configuration: Models with the stronger Dana 44 rear axle (optional) are more desirable, especially for serious off-roaders, and can add to the price.
• Modifications: Quality, tasteful modifications (e.g., well-installed lift, quality armor, winch) can add value, while poorly done or extreme modifications might detract from it.
• Geographic Location: Prices can vary by region due to demand, climate (rust concerns), and local supply.

Resources for Valuation:

• Kelley Blue Book (KBB.com): Provides a good starting point for private party and dealer values.
• NADA Guides (NADAGuides.com): Another reliable source for vehicle valuation.
• Online Marketplaces: Browse listings on Facebook Marketplace, Craigslist, AutoTrader, and dedicated Jeep forums (e.g., JeepForum.com, WranglerForum.com) to get a feel for current market prices in your area.

Estimated Price Range for a Used 2004 Jeep Wrangler Unlimited For Sale:

Please note that these are approximate ranges and can fluctuate based on market conditions, region, and specific options. The presence of a hardtop, the specific axle setup (Dana 44 rear), and desirable options like AC or cruise control can push prices higher.

Often includes desirable factory options (hardtop, Dana 44 rear) and/or high-quality, professional modifications. These are becoming collector’s items.

V. Tips for a Successful Purchase

1. Get a Pre-Purchase Inspection (PPI): This is non-negotiable for a vehicle of this age, especially one that may have been used off-road. Have a trusted mechanic (preferably one familiar with Jeeps) inspect it thoroughly for rust, mechanical issues, and any hidden problems.
2. Test Drive Thoroughly: Drive it on various surfaces – highway, city streets, and if possible, some mild unpaved roads to test the 4WD system. Listen for unusual noises, check for vibrations, and ensure all gears engage smoothly.
3. Review Maintenance Records: Ask the seller for all available service records. A well-documented history is a strong indicator of a cared-for vehicle.
4. Check the VIN: Use services like CarFax or AutoCheck to review the vehicle’s history for accidents, salvage titles, flood damage, and mileage discrepancies.
5. Negotiate: Don’t be afraid to negotiate the price, especially if the inspection reveals issues. Be prepared with your research on comparable sales.
6. Budget for Post-Purchase: Even a well-maintained LJ may need some immediate attention (e.g., fluid changes, new tires, or small repairs). Factor this into your budget. Also, consider potential upgrades you might want.

Frequently Asked Questions (FAQ) About the Used 2004 Jeep Wrangler Unlimited For Sale

Q: Is the 2004 LJ a good daily driver?
A: It can be, especially compared to the shorter TJ, due to its improved ride and cargo space. However, it’s still a rugged vehicle with a firm ride, basic interior, and relatively poor fuel economy. It’s best for someone who prioritizes adventure and versatility over luxury and quiet comfort.

Q: What’s the main difference between a TJ and an LJ?
A: The primary difference is the wheelbase. The LJ has a 103.4-inch wheelbase, which is 10 inches longer than the standard TJ’s 93.4-inch wheelbase. This translates to significantly more cargo space, more rear legroom, a smoother ride, and higher towing capacity for the LJ.

Q: How reliable is the 4.0L engine in the 2004 LJ?
A: The 4.0L inline-six is legendary for its reliability and durability. With proper maintenance, these engines can easily last well over 200,000 or even 300,000 miles. Common issues are usually minor, like oil leaks (especially the rear main seal) or occasional sensor failures.

Q: What’s the fuel economy like for a 2004 LJ?
A: Expect around 15-18 MPG on average, depending on driving style, tire size, and modifications. It’s not known for its fuel efficiency.

Q: Are parts readily available for the 2004 LJ?
A: Yes, absolutely. Since it shares many components with the widely popular TJ generation, aftermarket support is immense, and OEM parts are generally still available through Jeep dealers or online.

Q: What is "death wobble" and is the LJ susceptible to it?
A: "Death wobble" is a violent, uncontrollable oscillation of the front wheels, typically occurring at highway speeds after hitting a bump. It’s caused by worn or loose steering and suspension components (e.g., track bar, ball joints, tie rod ends, control arm bushings). While not exclusive to Jeeps, TJs/LJs can experience it if maintenance is neglected. It’s fixable but requires identifying and replacing the worn parts.

Q: Is a Used 2004 Jeep Wrangler Unlimited worth the higher price compared to a standard TJ?
A: For many buyers, yes. The added cargo space, rear passenger comfort, improved ride quality, and higher towing capacity make the LJ significantly more practical for daily use and extended trips, without sacrificing off-road prowess. Its limited production also contributes to its higher resale value.

Conclusion

The appeal of a Used 2004 Jeep Wrangler Unlimited For Sale is undeniable for those who value classic ruggedness, open-air freedom, and genuine off-road capability.
