The 1999 Grand Cherokee represents a pivotal moment in Jeep’s history, sitting at the crossroads of the model’s rugged past and its increasingly refined future. This specific year marked the transition between the ZJ platform and the introduction of the more sophisticated WJ, making it a year of significant interest for enthusiasts and buyers alike. Understanding the nuances of the 1999 model year helps clarify its place in the lineage of the iconic Cherokee.
Model Year Specifics and Trim Levels
For the 1999 model year, Jeep offered the Grand Cherokee across several distinct trim levels, each catering to different needs and budgets. The base Laredo trim provided essential features and capability, while the upwardly mobile Limited offered enhanced luxury with premium materials. At the top of the heap, the coveted Grand Cherokee 5.9 Limited, often simply called the 5.9, delivered serious off-road prowess wrapped in high-end appointments. This trim level is particularly sought after today due to its robust 5.9-liter V8 engine and specialized components.
Key Mechanical Differentiators
One of the most critical distinctions for the 1999 model year lies under the hood. The base models were typically equipped with the reliable 4.0-liter inline-six engine, mated to either the four-speed automatic 42RE transmission or the legendary NV247 transfer case. This combination provided dependable on-road manners and competent off-road performance. Conversely, the 5.9 Limited utilized the larger 5.2-liter Magnum V8, producing substantial power for its time and paired with the heavy-duty 46RE transmission and a standard Quadra-Drive system, significantly enhancing traction control.
Exterior and Interior Design Evolution
Visually, the 1999 Grand Cherokee carried the bold, aggressive stance established by its predecessors, featuring a distinctive trapezoidal grille and stacked headlamps that became its signature look. The body lines were muscular yet functional, hinting at its capable off-road nature without sacrificing daily drive comfort. Inside, the cabin moved away from the utilitarian feel of older Jeeps, embracing a more car-like environment with improved materials, better ergonomics, and a dashboard layout that placed essential controls within easy reach.

Performance and Capability Highlights
The 1999 Grand Cherokee was engineered to be as competent on the highway as it was on the trail. The available Quadra-Drive system marked a significant advancement, offering electronic limited-slip differentials at all four wheels for superior traction in challenging conditions. On the road, the suspension provided a balanced compromise between comfort and control, absorbing bumps effectively while maintaining a planted feel during spirited driving. The 5.9 variant, in particular, offered a thrilling driving experience that belied its size.
Common Issues and Maintenance Considerations
Owning a 1999 Grand Cherokee, like any vehicle of this age, requires awareness of potential pitfalls. Owners should be mindful of the 4.0-liter inline-six timing chain, which in some configurations has been known to exhibit excessive wear or failure if not addressed proactively. The transfer cases in the 4WD systems, particularly the NP247 and NP249 units, require diligent maintenance of their transfer case fluid to ensure smooth operation and prevent costly repairs. Regular checks of the ball joints, tie rods, and suspension components are also recommended given the vehicle's age and intended use.
