Understanding the Legend: What Makes the 5.9L Special?
The 1998 Jeep Grand Cherokee (ZJ generation) 5.9L Limited stands alone in its class and its lineage. Produced for only a single model year, it was Jeep’s answer to the burgeoning performance SUV market, a direct competitor to vehicles like the GMC Syclone/Typhoon, albeit with a different flavor.
At its heart lies the legendary 5.9-liter (360 cubic inch) Magnum V8 engine, borrowed from the Dodge Ram. This powerhouse delivered a robust 245 horsepower and a staggering 345 lb-ft of torque, a significant bump from the standard 5.2L V8’s 220 hp and 300 lb-ft. This power allowed the 5.9L Limited to sprint from 0-60 mph in a remarkable 7.1 seconds – an astonishing figure for an SUV of its size and era, making it the fastest production SUV in the world at the time.
But the 5.9L was more than just an engine swap. Jeep engineers went to great lengths to create a truly special vehicle:
- Performance Enhancements: Beyond the engine, it featured a stronger 46RE automatic transmission, a heavy-duty Dana 44a rear axle, and a standard full-time Quadra-Trac transfer case.
- Unique Exterior Styling: Distinguishing it from lesser ZJs were functional hood louvers for heat extraction, a unique mesh grille, a specific front bumper with integrated fog lights, polished 16-inch five-spoke alloy wheels, and a subtle "5.9 Limited" badge on the rear.
- Premium Interior: The cabin received an upgrade with heated, leather-trimmed seats (often with a unique perforated pattern), a full-length overhead console, a 180-watt Infinity Gold sound system with 10 speakers and a CD changer, and simulated carbon fiber trim. Even the leather-wrapped steering wheel was unique.
- Limited Production: Only approximately 14,000 units were produced worldwide, making it a relatively rare find and contributing to its collectibility.
This combination of raw power, subtle aesthetic upgrades, and exclusive features cemented the 5.9L Limited’s status as a unique, high-performance variant that stood head and shoulders above its contemporaries.

Navigating the Market: What to Look For When Buying (The Inspection Checklist)
Finding a 1998 Jeep Grand Cherokee 5.9L for sale requires a discerning eye. These vehicles are over two decades old, and their condition will vary wildly. A thorough inspection is paramount.
-
Rust: This is the number one enemy of older Jeeps.
- Frame Rails: Especially under the doors and rear wheel wells.
- Rocker Panels: Prone to rot.
- Floorboards: Check under the carpets, particularly the front footwells.
- Rear Quarter Panels: Around the wheel arches.
- Underbody: Inspect brake lines, fuel lines, suspension mounting points.
-
Engine (5.9L Magnum V8):
- Listen: For knocking, ticking (exhaust manifold leaks are common), excessive lifter noise, or unusual rattles.
- Oil Leaks: Check valve covers, oil pan, and especially the rear main seal (a common, but expensive, repair).
- Cooling System: Inspect radiator for leaks, check hoses, and ensure the electric fan and fan clutch operate correctly. Overheating issues are common if neglected.
- Heat Soak: Ask if the owner experiences hard starting when the engine is hot. This is a common 5.9L issue.
-
Transmission (46RE Automatic):
- Fluid: Check fluid level and condition. It should be red, not dark brown or burnt smelling.
- Shifting: During a test drive, ensure shifts are smooth, without harshness, slipping, or delayed engagement. Pay attention to the 1-2 shift.
-
Transfer Case (Quadra-Trac NP249):
- Leaks: Check for fluid leaks.
- Noise: Listen for grinding or clunking noises, especially when turning at low speeds (indicates a failing viscous coupler).
- Functionality: Ensure the 4WD system engages and disengages properly (though it’s full-time AWD).
-
Differentials: Check for leaks around the seals and listen for unusual noises during the test drive. The Dana 44a rear axle is stronger but can still have issues.
-
Suspension and Steering:
- Bushings: Inspect control arm bushings, sway bar bushings for cracks or wear.
- Ball Joints/Tie Rod Ends: Check for play.
- Steering Box: Look for leaks and excessive play in the steering wheel.
- Control Arms: Check for bending or damage if it’s been off-roaded.
-
Brakes: Inspect rotor condition, pad thickness, and look for fluid leaks.
-
Electrical System:
- Power Windows: Test all windows. The regulators and motors are notorious for failing.
- HVAC: Ensure the air conditioning blows cold and the heater works. Check the blend door actuator (common failure point, leading to no heat/AC or only one temperature side).
- Gauges & Lights: Test all dashboard lights and gauges.
- Infinity Gold System: Test all speakers.
-
Interior:
- Leather Seats: Look for tears, excessive cracking, or bolster wear.
- Headliner: Check for sagging, a common issue.
- Trim: Inspect the unique carbon fiber trim and other interior plastics for damage.
-
Exterior:
- 5.9L Specific Parts: Ensure the unique hood, grille, and wheels are present and in good condition. These are hard to replace.
- Paint: Look for fading, clear coat peel, or signs of accident repair.
-
Maintenance Records: Crucial for understanding the vehicle’s history, especially major services, fluid changes, and known issues addressed.
-
Test Drive: Drive at various speeds, including highway. Listen for unusual noises, feel for vibrations, check braking performance, and ensure the transmission shifts smoothly.
Common Challenges and Solutions for the 5.9L ZJ
Even a well-maintained 5.9L Grand Cherokee might present some common issues due to its age and design. Knowing these beforehand can help you budget for potential repairs.
- Heat Soak/Vapor Lock: The most famous 5.9L specific issue. Fuel in the rail vaporizes when hot, leading to hard starts after short shutdowns.
- Solution: Aftermarket heat shields for the fuel rail and injectors, wrapping fuel lines, or sometimes a simple blanket over the intake manifold when parked hot can help.
- Electrical Gremlins: Beyond power windows, issues like blend door actuators, intermittent gauge cluster readings, and stereo problems are common.
- Solution: Replacing faulty components, checking grounds, and consulting online forums for specific troubleshooting. Many parts are available aftermarket.
- Exhaust Manifold Bolts: Prone to breaking due to heat cycles, leading to ticking noises.
- Solution: Replacement bolts (often upgraded), or replacing with aftermarket headers.
- Transmission Longevity: While the 46RE is stronger, heavy use or lack of maintenance can lead to issues.
- Solution: Regular fluid and filter changes, adding an external transmission cooler, and considering a rebuild or upgrade for heavy towing or off-roading.
- Aging Plastics and Rubber: Interior trim can crack, and weather stripping can degrade.
- Solution: Aftermarket replacements, sourcing used parts, or creative DIY fixes.
Ownership and Maintenance Tips for Your 5.9L Grand Cherokee
Once you’ve found your perfect 5.9L, proper maintenance is key to its longevity and enjoyment.
- Regular Fluid Changes: Adhere to a strict schedule for engine oil (synthetic is recommended), transmission fluid, transfer case fluid, and differential fluids.
- Cooling System Health: Flush the coolant regularly, inspect hoses, radiator, and the fan clutch. Preventative maintenance here is crucial to avoid overheating.
- Address Issues Promptly: Don’t let small problems fester. A ticking exhaust manifold or a sticky power window motor can lead to larger, more expensive repairs if ignored.
- Source Quality Parts: While many parts are common with other Mopar vehicles, some 5.9L specific items can be harder to find. Utilize Mopar parts, reputable aftermarket suppliers, and be open to salvage yards for unique trim pieces.
- Join the Community: Online forums (like JeepForum.com, NAXJA.org) and local Jeep clubs are invaluable resources for troubleshooting, parts sourcing, and sharing knowledge.
