The Legend of the LJ: Why the 2004 Wrangler Unlimited Stands Out

Used 2004 Jeep Wrangler Unlimited For Sale: Your Comprehensive Guide to Finding the Legendary LJ

Before the four-door JK and JL generations redefined the Wrangler, there was the LJ. Introduced for the 2004 model year, the Jeep Wrangler Unlimited (TJ-L) was a revelation. While sharing the classic round headlights, seven-slot grille, and removable doors/top with the standard TJ Wrangler, the Unlimited brought a crucial advantage: space.

The standard TJ Wrangler had a 93.4-inch wheelbase. The Unlimited stretched this to a significantly more comfortable 103 inches, adding nearly 15 inches to the overall length. This extension wasn’t just for show; it translated directly into 13 inches of additional cargo room behind the rear seats and surprisingly improved rear passenger legroom. This made the LJ a far more practical vehicle for families, gear-hauling, or longer trips, without sacrificing an ounce of its famed off-road prowess. In fact, the longer wheelbase often improved stability on the highway and enhanced approach and departure angles in certain off-road scenarios.

Under the hood, the 2004 Wrangler Unlimited came standard with Jeep’s revered 4.0-liter inline-six (I6) engine. Known for its bulletproof reliability, ample low-end torque (190 horsepower and 235 lb-ft of torque), and ease of maintenance, this engine is a significant part of the LJ’s enduring appeal. Transmission options included a 4-speed automatic (42RLE) or a 5-speed manual (NV3550). Most LJs also came with a heavy-duty Dana 44 rear axle, a desirable upgrade for serious off-roaders, making them even more robust right out of the factory.

This unique combination of classic looks, legendary powertrain, and enhanced utility makes the Used 2004 Jeep Wrangler Unlimited For Sale a highly sought-after commodity. It represents the sweet spot for many enthusiasts: the simplicity and ruggedness of the TJ era, but with the added versatility that makes it a more viable daily driver or adventure rig.

What to Look For When Buying a Used 2004 Jeep Wrangler Unlimited

Acquiring a Used 2004 Jeep Wrangler Unlimited For Sale requires diligence. These vehicles are nearly two decades old, and their off-road nature means they’ve likely seen some tough terrain. A thorough inspection is paramount to avoid costly surprises down the road.

1. 

   Rust, Rust, Rust: This is the single biggest enemy of older Jeeps, especially in colder climates where salt is used on roads.

   • Frame: Inspect the entire frame, paying close attention to the skid plate mounts, control arm mounts, and especially the rear section around the bumper and gas tank skid. Look for flaking, bubbling, or perforations. Light surface rust is often manageable, but structural rust is a deal-breaker.
   • Body: Check the rocker panels, wheel wells, front fenders, and floorboards (under the carpet, especially in the front). Don’t forget the door hinges and windshield frame.
   • Underbody Components: Examine the exhaust, suspension components, and steering linkage for excessive rust.

2. Engine and Drivetrain:

   • 4.0L Engine: Listen for unusual noises (knocks, ticks, excessive lifter noise) upon cold start and when warm. Check for oil leaks around the valve cover, oil pan, and rear main seal. Look for coolant leaks around the radiator, hoses, and thermostat housing.
   • Transmission: For automatics, ensure smooth shifts without harshness or slipping. For manuals, check clutch engagement (no slipping or grinding) and smooth shifting through all gears.
   • Transfer Case (NV231 or NV241): Check for leaks. Engage 2H, 4H, and 4L. The lever should move smoothly, and the indicator light (if present) should illuminate. Listen for grinding or clunking noises.
   • Axles: Check for leaks at the differential covers and pinion seals. Listen for humming or whining noises during the test drive, which could indicate worn gears or bearings.

3. Suspension and Steering:

   • Components: Inspect ball joints, tie rod ends, track bar, control arm bushings, and shocks for wear, looseness, or leaks. Worn components can lead to poor handling and the dreaded "death wobble."
   • Lift Kits: Many LJs are lifted. Ensure the lift kit was professionally installed and all components (control arms, driveshafts, brake lines, etc.) are appropriate for the lift height and in good condition. Improperly installed lifts can cause significant issues.

4. Electrical System: Test all lights (headlights, tail lights, turn signals, brake lights), gauges, wipers, horn, radio, HVAC controls, and any power windows/locks (if equipped). Pay attention to any warning lights on the dashboard.

5. Interior and Soft Top/Hard Top:

   • Interior: Check for excessive wear, tears in seats, non-functioning seat belts, and dampness under the carpets (indicates water leaks).
   • Tops: If it has a soft top, inspect for rips, tears, and clarity of the plastic windows. If it has a hard top, check for cracks or damage and ensure all mounting points are secure. Check door seals and windshield frame seals for signs of leaks.

6. Tires and Brakes:

   • Tires: Check tread depth and ensure even wear. Uneven wear can indicate alignment issues or worn suspension components.
   • Brakes: Check rotor condition (no deep grooves or excessive rust), pad thickness, and brake fluid level. During a test drive, ensure the brakes are firm and stop the vehicle smoothly without pulling or pulsing.

7. Documentation: Ask for service records to understand the vehicle’s maintenance history. A CarFax or AutoCheck report can reveal accident history, previous owners, and mileage discrepancies.

Test Driving Your Prospective 2004 Jeep Wrangler Unlimited

A thorough test drive is crucial. Don’t just drive around the block.

• On-Road: Drive at various speeds, including highway speeds if possible, to check for vibrations, steering wander, and proper alignment. Listen for any unusual noises from the engine, transmission, or differentials. Test braking performance under normal and firmer conditions.
• Off-Road (If Permitted and Safe): If possible, find a safe, mild off-road area to test 4WD high and low ranges. Ensure they engage and disengage smoothly. Listen for any binding or clunking. This also allows you to test the suspension through articulation.
• Steering: Pay attention to how the steering feels. Is there excessive play? Does it pull to one side? Does it return to center easily?

Understanding the Value and Pricing of a Used 2004 Jeep Wrangler Unlimited

The market for a Used 2004 Jeep Wrangler Unlimited For Sale is unique. Unlike many vehicles that depreciate linearly, the LJ has held its value remarkably well, often appreciating due to its rarity and desirable features. Factors influencing price include:

• Condition: This is the primary driver. A rust-free, well-maintained LJ will command a premium.
• Mileage: Lower mileage generally means higher prices, but maintenance history is arguably more important than absolute mileage for a vehicle of this age.
• Modifications: Quality, well-executed modifications (e.g., proper lift, good tires, winch) can add value, but poorly done or extreme modifications can detract from it.
• Trim Level: While the 2004 LJ wasn’t offered in a Rubicon trim (that came in 2005-2006 for the LJ), Sport and Sahara trims were available. The base Sport is generally less expensive than a Sahara with more options.
• Location: Prices can vary regionally based on demand and climate (less rust in arid regions, potentially higher prices).

Be prepared for the "Jeep Tax" – these vehicles are in high demand and their owners know their value. It’s not uncommon for clean, low-mileage LJs to fetch prices comparable to much newer vehicles.

Ownership Experience & Common Modifications for the 2004 LJ

Owning a Used 2004 Jeep Wrangler Unlimited For Sale is an experience. It’s a vehicle that offers immense freedom and fun, but it comes with its quirks.

• Grease Zerk Fittings: Regularly grease steering and suspension components.
• Check for Leaks: Periodically inspect for any fluid leaks.

Practical Advice and Actionable Insights

When pursuing a Used 2004 Jeep Wrangler Unlimited For Sale:

• Get a Pre-Purchase Inspection (PPI): Even if you’re handy, have a trusted mechanic (preferably one familiar with Jeeps) perform a thorough inspection. This can uncover hidden issues.
• Don’t Rush: The right LJ will come along. Be patient and don’t settle for a vehicle with major red flags.
• Budget for the Unexpected: Factor in potential repair costs and immediate maintenance/upgrade needs. An older vehicle will always require some investment.
• Negotiate Wisely: Use any identified issues from the inspection as leverage in price negotiation.
• Consider Your Use: Are you looking for a daily driver, a weekend trail rig, or a showpiece? Your intended use will influence how much wear and tear you’re willing to accept.
