II. Under the Hood: Powertrain Options and Performance

The heart of any vehicle lies in its powertrain, and the 1991 Jeep Cherokee offered robust and well-proven options that contributed significantly to its legendary status.

• Engines:

  • 2.5L AMC I4 (Throttle Body Injection – TBI): This inline-four-cylinder engine, producing around 121 horsepower and 149 lb-ft of torque, was the standard offering. While adequate for light duty and economy, it was often overshadowed by its more powerful sibling.

  

  • 4.0L AMC I6 (High Output – HO): This is the engine that truly defined the XJ. Introduced in 1991 as the "High Output" version, it featured a revised cylinder head, intake manifold, and fuel injection system, boosting power to 190 horsepower and 225 lb-ft of torque. This substantial increase transformed the Cherokee’s performance, making it remarkably spirited for its size and era. The 4.0L HO is revered for its legendary reliability, strong low-end torque, and ease of maintenance, making it the overwhelming favorite among enthusiasts.

• Transmissions:

  

  • Aisin-Warner AW4 Automatic: A remarkably durable and efficient 4-speed automatic transmission, often praised for its smooth shifts and longevity. It’s a staple in the XJ community and widely regarded as bulletproof.
  • Aisin AX-15 Manual: A 5-speed manual transmission, also known for its robustness. While less common than the automatic, it offers more direct control and is preferred by some for serious off-roading.



• Drivetrain & Axles:

  • Command-Trac (NP231): The standard part-time 4WD system, offering 2WD, 4-High Part-Time, and 4-Low. It’s robust and simple, ideal for off-road use but not for continuous use on dry pavement in 4WD.
  • Selec-Trac (NP242): An optional full-time 4WD system, providing 2WD, 4-High Part-Time, 4-High Full-Time, Neutral, and 4-Low. The "Full-Time" mode allows for safe use on any surface, making it more versatile for varied conditions.
  • Axles: The 1991 Cherokee typically featured a Dana 30 front axle and either a Dana 35C or a Chrysler 8.25-inch rear axle. While the Dana 35C can be a weak point for aggressive off-roading, the Chrysler 8.25 (often found in 4.0L models with the AW4) is a stronger alternative, and both are easily upgraded with aftermarket components.

III. Design and Interior: Form Meets Function

The 1991 Jeep Cherokee’s design is a masterclass in functional aesthetics. Its boxy, upright silhouette is instantly recognizable and has aged remarkably well.

• Exterior: The straight lines and minimal overhangs contribute to excellent approach and departure angles, crucial for off-road capability. The compact wheelbase (101.4 inches) also aids maneuverability in tight trails. The large glass area provides superb visibility, a feature often sacrificed in modern SUVs. Available in two-door and four-door configurations, the four-door was by far the more popular and practical choice.

• Interior: Step inside a 1991 Cherokee, and you’ll find an interior designed for durability and practicality rather than luxury. Hard plastics dominate, but they are robust and easy to clean. The dashboard layout is straightforward, with clear, analog gauges. While creature comforts were basic by today’s standards (manual windows and locks were common on lower trims), higher trims like the Laredo and Limited offered power accessories, air conditioning, and improved upholstery. The seats, while not overly plush, provide decent support for both daily driving and off-road excursions. Cargo space is ample, especially with the rear seats folded down, making it a surprisingly capable hauler.

• Trim Levels (1991):

  • Base (Pioneer): The no-frills workhorse, often with manual windows and simpler interiors.
  • Sport: Added sportier trim, often with black exterior accents and standard 4.0L HO engine.
  • Laredo: A popular mid-range trim, offering more chrome, power amenities, and upgraded interior fabrics.
  • Limited: The top-tier luxury trim, featuring leather upholstery, power seats, and more standard features.
  • Briarwood: A wood-paneled variant, unique and offering a more classic station wagon feel.

IV. Off-Road Prowess and Daily Driveability

The 1991 Jeep Cherokee’s reputation as an off-road legend is well-earned. Its combination of a unibody chassis, solid axles, excellent ground clearance, and robust drivetrain components makes it incredibly capable on trails, rocks, and mud. The short wheelbase allows it to navigate tight turns, while the ample articulation of its suspension keeps tires on the ground over uneven terrain.

Despite its off-road focus, the XJ also proved to be a surprisingly competent daily driver for its era. The unibody construction provided a more comfortable and quieter ride than traditional body-on-frame trucks. The 4.0L HO engine offered brisk acceleration for merging onto highways, and its compact size made it relatively easy to maneuver in urban environments. However, potential owners should be aware that compared to modern SUVs, the 1991 Cherokee will feel less refined, with more road noise, a firmer ride, and less precise steering. Fuel economy, particularly with the 4.0L, is also modest by contemporary standards.

V. Ownership in 2024: What to Look For and Maintain

Owning a 1991 Jeep Cherokee in the present day is a rewarding experience, but it comes with considerations typical of a 30-plus-year-old vehicle.
