2004 Jeep Rubicon Unlimited For Sale: The Ultimate Guide to Finding Your Dream LJ jeeps.truckstrend.com
In the vast landscape of off-road vehicles, few command the same reverence and desirability as the Jeep Wrangler. Within that iconic lineage, certain models stand out as true legends. Among them, the 2004 Jeep Rubicon Unlimited – affectionately known as the "LJ" by enthusiasts – holds a particularly hallowed place. This article serves as a comprehensive guide for anyone looking to understand, acquire, or appreciate this rare and highly sought-after off-road machine. Whether you’re a seasoned Jeeper or a newcomer to the trail, understanding what makes the 2004 Rubicon Unlimited so special is the first step toward finding your perfect adventure companion.
The 2004 Jeep Rubicon Unlimited isn’t just another Wrangler; it’s a unique blend of the classic TJ’s rugged simplicity and the extended wheelbase that enhances both off-road stability and on-road comfort. Released for a limited production run, the LJ combines the hardcore off-road features of the Rubicon package with an additional 10 inches of wheelbase over the standard TJ Wrangler. This elongation provides a smoother ride, increased cargo space, and improved approach/departure angles, making it arguably the most balanced and capable factory-built Wrangler of its era. For sale, these vehicles represent a rare opportunity to own a piece of Jeep history that continues to outperform many modern off-roaders straight off the lot.

The Legend of the LJ: Why the 2004 Rubicon Unlimited Stands Out
The "LJ" designation refers to the Long-wheelbase Jeep, specifically the TJ-generation Wrangler Unlimited. While the standard TJ Wrangler has a 93.4-inch wheelbase, the LJ stretches to 103.4 inches. This seemingly minor difference has a profound impact. The extended wheelbase significantly improves stability at speed and on challenging climbs, reduces the likelihood of "porpoising" over bumps, and offers a more controlled ride. It also provides a surprising amount of additional cargo room behind the rear seats – a common complaint with the standard TJ.
What truly elevates the 2004 Unlimited to legendary status, however, is the combination of this extended wheelbase with the coveted Rubicon package. The Rubicon trim, introduced in 2003, brought factory-installed, hardcore off-road equipment that was previously only available through aftermarket modifications. This includes:
- Dana 44 Heavy-Duty Axles: Both front and rear, significantly stronger than the standard Dana 30 front and Dana 35 rear axles.
- Air-Actuated Tru-Lok Front and Rear Lockers: These allow both wheels on an axle to spin at the same speed, providing maximum traction in extreme conditions.
- 4:1 Rock-Trac Transfer Case: A low-range gear ratio of 4:1 (compared to 2.72:1 in standard TJs) provides incredible crawl control for navigating technical terrain.
- Lower Gearing: Typically 4.10:1 axle ratios (compared to 3.73:1 or 3.07:1), optimized for off-road performance.
- Disconnecting Front Sway Bar: Allows for increased wheel articulation on trails.
- Diamond Plate Rocker Guards: Factory protection for the vehicle’s vulnerable sills.
Powered by Jeep’s legendary 4.0-liter PowerTech Inline-Six engine, renowned for its bulletproof reliability and ample low-end torque, the 2004 Rubicon Unlimited offers an unparalleled blend of capability, durability, and classic Jeep character.

What to Look For: A Buyer’s Guide to the 2004 LJ Rubicon
Purchasing a nearly two-decade-old off-road vehicle requires careful inspection. Here’s what to prioritize when looking at a 2004 Jeep Rubicon Unlimited for sale:
- Frame Rust: This is paramount. Inspect the frame thoroughly, especially near the control arm mounts, skid plate mounts, and rear sections. Surface rust is common and manageable, but severe rot or flaky rust is a red flag. Pay close attention to the areas around the transmission skid plate and the trailing arm mounts.
- Engine Condition:
- Check for oil leaks (rear main seal, oil pan gasket, valve cover gasket are common).
- Listen for unusual noises (knocking, ticking).
- Check coolant for contamination.
- Ensure proper idle and acceleration.
- Confirm routine maintenance records (oil changes, tune-ups).
- Transmission:
- Manual: Check for smooth shifts, no grinding, and proper clutch engagement.
- Automatic: Ensure smooth shifts, no slipping, and proper fluid levels/color.
- Axles and Lockers:
- Confirm the lockers engage and disengage properly. You’ll hear an air pump activate. Test them on a loose surface (like dirt or gravel) if possible, but never on pavement.
- Listen for any grinding or clunking from the differentials during turns or acceleration.
- Suspension and Steering:
- Inspect all suspension components (control arms, bushings, shocks, springs) for wear, damage, or leaks.
- Check steering components (tie rod ends, ball joints, steering box) for play.
- Look for signs of recent alignment issues or uneven tire wear.
- Aftermarket Modifications: Many LJs have been modified.
- Quality over Quantity: Look for high-quality components from reputable brands.
- Professional Installation: Poorly installed lifts, wiring, or armor can cause more problems than they solve.
- Purpose: Understand why modifications were done. A heavily modified vehicle might indicate hard use.
- Body and Interior:
- Check for body rust, especially around the fenders, rocker panels, and door hinges.
- Inspect the soft top/hard top for tears, leaks, or damage.
- Ensure all lights, gauges, and electrical components (windows, radio, AC) work.
- Documentation: Request service records, receipts for parts/mods, and a clean title. A CarFax or AutoCheck report is highly recommended to verify mileage and accident history.
The Ownership Experience: Benefits and Challenges
Owning a 2004 Jeep Rubicon Unlimited is a unique experience, offering both significant rewards and a few considerations.
Benefits:
- Unmatched Off-Road Capability: Stock for stock, few vehicles can match its performance on the trail.
- Timeless Design: The classic Wrangler aesthetic never goes out of style.
- Strong Aftermarket Support: A vast array of parts and accessories are available for customization and repair.
- Holds Value Well: Due to its limited production and legendary status, LJs tend to depreciate slowly and often appreciate if well-maintained.
- Versatility: Capable on the trail, surprisingly good for overlanding due to extra space, and can serve as a quirky daily driver.
- Community: Joining the Jeep community provides access to a wealth of knowledge and camaraderie.
Challenges:
- Fuel Economy: The 4.0L engine, while reliable, is not fuel-efficient by modern standards.
- Maintenance: As an older vehicle, expect regular maintenance and potential repairs. Parts are generally available and affordable, but labor costs can add up if you don’t DIY.
- Ride Quality: While better than a standard TJ, it’s still a solid-axle, short-wheelbase (by modern SUV standards) vehicle. It’s rugged, not luxurious.
- Rust: A persistent issue in colder climates where salt is used on roads.
- Finding a Good Example: Many LJs have been heavily modified, abused, or neglected. Finding a well-maintained, unmolested, or professionally built example can take time and effort.
Maximizing Value: Tips for Sellers and Buyers
For Sellers:
- Thorough Cleaning: A clean vehicle, inside and out, makes a strong first impression.
- Detailed Photos: Take high-quality photos from all angles, including interior, engine bay, undercarriage (especially the frame), and any specific features.
- Comprehensive Description: Be honest and detailed about the vehicle’s condition, maintenance history, modifications (and why they were done), and any known issues. Transparency builds trust.
- Service Records: Compile all maintenance and repair records. This adds significant value.
- Competitive Pricing: Research comparable sales in your area and nationwide. Price it fairly based on condition, mileage, and modifications.
- Be Prepared for Questions: Enthusiasts will ask detailed questions. Know your vehicle inside and out.
For Buyers:
- Patience is Key: Don’t rush into a purchase. The right LJ will come along.
- Pre-Purchase Inspection (PPI): Always get a professional mechanic (preferably one familiar with Jeeps) to inspect the vehicle before buying, even if it looks perfect.
- Test Drive Extensively: Drive it on various surfaces, including highway speeds, to check for vibrations, steering issues, and overall performance. Test 4WD.
- Research Comparable Sales: Use online marketplaces to understand the market value based on condition and features.
- Negotiate Wisely: Don’t be afraid to negotiate, but be realistic. A well-maintained LJ is a valuable asset.

Frequently Asked Questions (FAQ)
Q1: Is the 2004 Jeep Rubicon Unlimited a good daily driver?
A1: It can be, but it’s not designed for comfort or fuel efficiency like a modern SUV. It’s a rugged vehicle with a firm ride, higher road noise, and basic amenities. For some, its character makes it an enjoyable daily driver; for others, it’s best as a weekend warrior or secondary vehicle.
Q2: What’s the main difference between a standard TJ and an LJ?
A2: The LJ (Unlimited) has a 10-inch longer wheelbase (103.4" vs. 93.4") than the standard TJ, providing more rear passenger legroom, significantly more cargo space, and improved on-road stability and off-road breakover angle.
Q3: What are the most common problems to look out for on a 2004 LJ?
A3: Frame rust (especially in northern climates), exhaust manifold cracks, oil leaks (rear main seal), power steering pump leaks, and aging suspension components are common issues due to age and typical Jeep usage.
Q4: Are parts readily available for the 2004 LJ?
A4: Yes, absolutely. The TJ/LJ platform shares many components, and the aftermarket support is massive. You’ll have no trouble finding parts for maintenance, repair, or modification.
Q5: Is the 2004 Rubicon Unlimited worth the higher price compared to other TJs?
A5: For many enthusiasts, yes. The factory Dana 44 axles with lockers, the 4:1 transfer case, and especially the longer wheelbase make it a unique and highly capable platform that would cost significantly more to build from a standard TJ. Its rarity also contributes to its higher value.
Q6: How much lift and what tire size can I run on a stock 2004 LJ Rubicon?
A6: Stock, the Rubicon can typically clear 31-inch tires. With a mild 2-3 inch lift, 33-inch tires are common. With more extensive modifications (4+ inch lift, fender trimming), 35-inch tires are achievable.
Conclusion
The 2004 Jeep Rubicon Unlimited is more than just a vehicle; it’s an icon, a highly capable machine, and a cherished piece of off-road history.

While finding a well-maintained example requires patience and thorough inspection, the reward of owning such a versatile and legendary Jeep is immeasurable. For those seeking the ultimate blend of classic Wrangler charm and unparalleled factory off-road prowess, the 2004 Jeep Rubicon Unlimited remains an exceptional choice, promising countless adventures for years to come.
