The 2004 Jeep Wrangler is a compact, body-on-frame SUV built for trail use, open-air driving, and simple, rugged ownership. This model year is part of the TJ generation (1997–2006), known for its coil-spring suspension that improved ride quality and articulation versus earlier leaf-spring Wranglers. It’s ideal for buyers who prioritize off-road capability and classic Jeep character over quiet highway manners. In the used market, the 2004 Wrangler is often sought after for its strong aftermarket support and straightforward mechanical layout.

- TJ GENERATION 4X4 HARDWARE: Available Command-Trac part-time 4WD with a 2-speed transfer case, solid front and rear axles, and excellent approach/departure angles for trail use. - ENGINE OPTIONS: Most 2004 Wranglers came with the 4.0L inline-6, a proven, torque-rich engine favored for durability and low-end pulling power; some trims also offered a 2.4L inline-4 for budget-minded buyers. - TRANSMISSIONS: Available manual and automatic transmissions depending on configuration, with the manual often preferred by off-roaders for control and simplicity. - OPEN-AIR CONFIGURATIONS: Soft top or hardtop availability, removable doors, and a fold-down windshield design that define the Wrangler experience. - AFTERMARKET AND MOD POTENTIAL: The 2004 Wrangler has extensive support for lift kits, bumpers, gearing, lockers, wheels/tires, and armor, making it one of the easiest SUVs to personalize.

Shoppers researching 2004 Jeep Wrangler reliability will find that many owners consider the drivetrain robust, especially with the 4.0L inline-6, but there are several well-known 2004 Jeep Wrangler problems to watch for. - FRAME RUST, ESPECIALLY REAR SECTIONS: Rust can be a major issue in salt-belt states, often showing up on the rear frame rails, control arm mounts, and around skid plate mounting points. Severity varies widely by region and prior care, but significant rust can appear by 10+ years/100,000+ miles if underbody protection was neglected. - EXHAUST MANIFOLD CRACKS/LEAKS (4.0L): A ticking sound on cold start can indicate an exhaust manifold crack or gasket leak. This is a common wear issue that can show up around 80,000–150,000 miles, and it’s often more annoying than catastrophic, but it should be repaired to prevent further leaks and sensor-related issues. - OIL SEEPAGE AND COMMON SEALS: Owners frequently report oil leaks from the rear main seal and valve cover gasket on higher-mileage examples (often 100,000+ miles). These leaks are usually manageable but can drip onto the driveway and should be addressed to keep oil levels stable. - STEERING “DEATH WOBBLE” AND FRONT-END WEAR: Some 2004 Wrangler common issues include steering shake at speed after hitting a bump, typically tied to worn track bar bushings, tie-rod ends, ball joints, wheel balance, or improper alignment—often aggravated by larger tires or suspension lifts. It’s typically fixable, but it requires a proper diagnosis rather than guesswork.
