The Enduring Appeal: What Defines the 2000 Jeep Cherokee Sport?

2000 Jeep Cherokee Sport: The Unyielding Legend of the XJ Era

The 2000 Jeep Cherokee Sport is a compact SUV that, despite its unibody construction, possesses off-road capabilities that rival many body-on-frame trucks. It was designed for practicality and durability, not luxury or excessive creature comforts.

Key Characteristics:

• Engine: Primarily powered by the legendary 4.0-liter "PowerTech" inline-six engine, known for its torque, longevity, and relative simplicity.
• Transmission: Most commonly paired with the Aisin-Warner AW4 4-speed automatic transmission, though a 5-speed manual (AX-15) was also available, albeit less common, especially in the Sport trim for 2000.
• Drivetrain: Offered with two primary 4×4 transfer cases: the NP231 Command-Trac (part-time 4WD) and the NP242 Selec-Trac (full-time 4WD with a 2WD option). Rear-wheel drive (2WD) models were also available.
• Axles: Typically featured a Dana 30 front axle and either a Chrysler 8.25 or Dana 35 rear axle, depending on the configuration. The Chrysler 8.25 is generally preferred for its strength.
• Unibody Construction: Unlike traditional body-on-frame SUVs, the XJ’s unibody design contributes to its relatively lighter weight and car-like handling on pavement, without significantly compromising its off-road prowess.



• Sport Trim: The "Sport" trim level was one of the most popular, offering a balance of essential features without the frills of higher trims. It typically included cloth seating, manual windows/locks (though power options were common), and a no-nonsense interior, emphasizing its utilitarian roots.

The 2000 model year is particularly notable as it was the second-to-last year of XJ production, making it one of the most refined in terms of factory improvements before the model’s discontinuation. However, it also introduced a specific engine head casting (0331) that would become a point of concern for some owners.

The Heart of the Beast: Engine and Drivetrain Dynamics

The 4.0L inline-six engine is arguably the cornerstone of the XJ Cherokee’s legend. Producing 190 horsepower and 225 lb-ft of torque, it delivers robust, low-end power, making it excellent for off-road crawling and capable highway cruising. Its simple design, with only one head gasket and fewer moving parts than a V-configuration engine, contributes to its impressive durability. Many XJs with the 4.0L have surpassed 200,000 and even 300,000 miles with proper maintenance.

Transmission Options:

• AW4 Automatic: Renowned for its strength and reliability, the AW4 is a workhorse that can handle significant abuse. Regular fluid and filter changes are key to its longevity.
• AX-15 Manual: While rarer for the 2000 Sport, this 5-speed manual transmission offers a more engaging driving experience and is also quite robust.

Transfer Cases:

• NP231 Command-Trac: A part-time 4WD system (2WD, 4-Hi Part-Time, N, 4-Lo Part-Time). Ideal for off-road use, but not for driving on dry pavement in 4WD as it can cause drivetrain binding.
• NP242 Selec-Trac: A full-time 4WD system (2WD, 4-Hi Full-Time, 4-Hi Part-Time, N, 4-Lo Part-Time). The "Full-Time" mode is excellent for varied conditions like snow or light gravel roads, allowing for slippage between axles.

The combination of the 4.0L, AW4, and either the NP231 or NP242 makes for a highly capable and durable powertrain, a primary reason for the XJ’s enduring popularity among enthusiasts and off-roaders.

Common Issues, Important Considerations, and Solutions

While robust, the 2000 Jeep Cherokee Sport is not without its quirks and common issues, especially given its age. Awareness and proactive maintenance are crucial for ownership.

1. Rust: This is the XJ’s Achilles’ heel. Check rocker panels, floor pans, frame rails (unibody rails), and door bottoms. Solutions range from patching to full replacement panels.
2. Cooling System: The 4.0L runs hot. Overheating can lead to serious issues, including head cracks (see below). Regularly inspect the radiator, water pump, thermostat, fan clutch, and hoses. A complete cooling system overhaul is often recommended for new owners.
3. "0331" Cylinder Head: Specific to 2000-2001 4.0L engines, this cylinder head casting is prone to cracking, often between cylinders 3 and 4, leading to coolant loss and overheating. Look for coolant in the oil (milky oil), excessive steam from the exhaust, or persistent overheating. Solutions involve replacing the head with an updated "TUPY" head or an aftermarket performance head.
4. Crank Position Sensor (CPS): A common failure point that can cause no-start conditions, stalling, or erratic RPMs. Relatively easy to replace.
5. Oil Leaks: Common culprits include the rear main seal (a larger job) and the valve cover gasket (simpler). Address these to prevent oil loss and environmental impact.
6. Leaf Spring Sag: Over time, the rear leaf springs can flatten, reducing ride height and causing a harsher ride. Aftermarket lift springs are a common upgrade that also addresses this.
7. "Death Wobble": A violent, uncontrollable shaking of the front end, usually triggered by hitting a bump at speed. This is not specific to the XJ but can be caused by worn steering components (tie rod ends, ball joints, track bar, control arm bushings), poor alignment, or unbalanced tires. Diagnosis and replacement of worn parts are key.

Practical Advice: When considering a 2000 XJ, prioritize one with minimal rust and a strong, well-maintained engine. Be prepared for potential cooling system and cylinder head issues, especially if the vehicle’s history is unknown.

Buying Guide: What to Look For in a Used 2000 Cherokee Sport

Purchasing a 20-year-old vehicle requires a thorough inspection. Here’s a checklist:

1. Rust, Rust, Rust: Inspect the frame rails, rocker panels, floorboards (from underneath and inside by lifting carpets), and around the wheel wells. Surface rust is manageable; structural rust is a major red flag.
2. Engine Health:
   • Cold Start: Listen for knocking, ticking, or grinding.
   • Oil: Check the dipstick for milky appearance (coolant in oil) or excessively dark/gritty oil.
   • Coolant: Check the reservoir for oil contamination or low levels.
   • Exhaust: Look for excessive white smoke (coolant) or blue smoke (oil).
   • Leaks: Inspect under the vehicle for oil, coolant, or transmission fluid leaks.
3. Transmission: Test all gears, including reverse. Shifts should be smooth, not harsh or delayed. For 4×4, engage 4-Hi and 4-Lo (on a loose surface) to ensure the transfer case works.
4. Suspension & Steering: Drive over bumps to listen for clunks or squeaks. Check for excessive play in the steering wheel. Look for worn bushings or torn boots on steering components.
5. Interior & Electrical: Check all lights, gauges, power windows/locks (if equipped), HVAC system, and radio. Ensure seats are not torn beyond repair.
6. Aftermarket Modifications: Be wary of poorly installed lift kits or extensive modifications that might hide underlying issues or compromise safety. Professional installations are preferable.
7. Service Records: Ask for any maintenance history. This provides insight into how well the vehicle was cared for.
