Lot 04-7647C: 2004 Jeep Wrangler X

Great question! The 2004 Jeep Wrangler X (TJ generation) is actually considered one of the more reliable years, but like any 20-year-old vehicle, it has its share of common issues to watch for. Here are the most frequent problems you should know about:

TOP 6 MOST COMMON PROBLEMS:

1. Exhaust Manifold Cracks 🔧 Most Critical

   • The 4.0L engine’s exhaust manifold is notorious for developing cracks
   • You’ll hear a ticking sound, especially when cold
   • Fix: Replacement manifold ($300-800)
   • This one’s important because exhaust leaks can damage other components

2. Radiator Leaks 💧 Medium Priority

   • Factory radiators with plastic end tanks are leak-prone
   • Watch for coolant puddles or overheating
   • Fix: All-aluminum replacement radiator ($200-500)

3. Steering Linkage Wear 🎮 Safety Critical

   • Factory steering components wear out faster than expected
   • Can cause loose steering feel and safety issues
   • Fix: Replace worn components ($200-600)

4. Blower Motor Resistor Failure 🌬️ Annoying but Easy

   • Controls your HVAC fan speeds - commonly fails
   • Fan will only work on certain speeds or not at all
   • Fix: Easy DIY replacement ($50-150)

5. Window Regulator Failures 🪟 Minor Inconvenience

   • Electric window mechanisms frequently break
   • Window gets stuck or makes grinding noises
   • Fix: Replace regulator ($100-200 per window)

6. Exhaust Manifold Stud Issues 🔩 2000-2006 Specific

   • The studs connecting manifold to catalytic converter loosen
   • Causes exhaust leaks and ticking sounds
   • Fix: Re-torque or replace studs ($100-300)

GOOD NEWS: The 2004 model year is actually considered one of the better TJ years! Jeep had worked out many of the early electrical gremlins by then, and the 4.0L engine is legendary for its durability when properly maintained.

For this specific yellow Wrangler you’re looking at: With only 54k miles and being a Columbia Edition, it’s actually a pretty solid choice. Just have a mechanic check that exhaust manifold carefully during your inspection!
