Known for its ruggedness, distinctive styling, and surprising capability, the KJ Cherokee offers a unique blend of old-school Jeep charm and modern convenience. Whether you're considering buying one, already own one, or are simply curious about this generation, this comprehensive guide is for you. We'll cover everything from its specs and features to common problems and maintenance tips, ensuring you have all the information you need about the third generation Jeep Cherokee.

Overview of the 3rd Generation Jeep Cherokee (KJ)

The Jeep Cherokee KJ, produced from 2002 to 2007, marked a significant departure from its predecessors. Ditching the traditional boxy design for a more rounded, modern look, the KJ aimed to attract a broader audience while retaining Jeep's core off-road DNA. This generation, also known as the Liberty in North America, came with two engine options: a 3.7-liter V6 and a 2.4-liter inline-4. The V6 quickly became the more popular choice due to its increased power and torque, making it better suited for both on-road driving and off-road adventures.

The third generation Jeep Cherokee also introduced independent front suspension, a first for the Cherokee line, which improved ride quality and handling. However, this change also sparked debate among purists who felt it compromised the vehicle's off-road prowess. Despite the controversy, the KJ Cherokee offered impressive capabilities, especially when equipped with the available four-wheel-drive systems. Over its production run, the KJ saw several updates and special editions, each adding unique features and styling tweaks. From the Renegade trim with its rugged appearance to the upscale Limited edition, there was a KJ Cherokee for almost every taste and budget.

Key Specs and Features

Let's break down the nitty-gritty details of the 3rd generation Jeep Cherokee. Understanding the specs and features will give you a clearer picture of what this vehicle offers and how it performs.

Engine Options

• 2.4-liter Inline-4: Producing around 150 horsepower and 165 lb-ft of torque, this engine was the base option. While adequate for daily commuting, it often felt underpowered, especially when the vehicle was loaded with passengers or cargo.
• 3.7-liter V6: This engine was the more popular and capable choice, delivering approximately 210 horsepower and 235 lb-ft of torque. The V6 provided better acceleration and towing capacity, making it a more versatile option for various driving conditions.

Transmission

• 5-speed Manual: Available with both the inline-4 and V6 engines, the manual transmission offered a more engaging driving experience and slightly better fuel economy.
• 4-speed Automatic: The automatic transmission was the more common choice, providing smooth and convenient shifting. However, some owners have reported issues with its reliability over time.

Drivetrain

• Rear-Wheel Drive (RWD): Standard on the base models, RWD provided adequate performance for on-road driving.
• Part-Time Four-Wheel Drive: This system required manual engagement and was best suited for off-road use. It provided excellent traction in slippery conditions but was not intended for continuous use on paved roads.
• Full-Time Four-Wheel Drive: Available on higher trim levels, this system allowed for on-the-fly shifting between 2WD and 4WD, providing added convenience and versatility.

Suspension and Off-Road Capabilities

• Independent Front Suspension: The IFS improved ride quality and handling on paved roads.
• Solid Rear Axle: The solid rear axle provided durability and articulation for off-road use.
• Ground Clearance: With around 8 inches of ground clearance, the KJ Cherokee could tackle moderately challenging terrain.
• Approach and Departure Angles: The approach and departure angles were decent, allowing the vehicle to navigate obstacles without scraping the front or rear bumpers.

Interior and Features

Inside, the 3rd generation Jeep Cherokee offered a comfortable and functional cabin. Depending on the trim level, features included:

• Air conditioning
• Power windows and locks
• Cruise control
• CD player
• Available leather seats
• Sunroof

While the interior wasn't luxurious, it was durable and well-suited for the demands of off-road adventures.

Electrical Problems
