The Jeep Cherokee (XJ): A Comprehensive Buyer's Guide

The Jeep Cherokee (XJ) is a compact SUV produced by Jeep from 1984 to 2001 in the United States (and continuing later in other markets). It's renowned for its unibody construction, off-road capabilities, and boxy, utilitarian design. The XJ Cherokee pioneered the modern SUV segment, offering a blend of car-like comfort and truck-like toughness that made it immensely popular. It remains a highly sought-after vehicle today, especially among off-road enthusiasts and those seeking a reliable and affordable classic SUV.

Generations

First Generation (XJ; 1984-2001)

• 1984-1996: Early models featured the AMC 2.5L inline-four and the GM-sourced 2.8L V6. The 4.0L inline-six, widely regarded as the best engine option, was introduced in 1987. The interior was relatively basic, and the exterior design remained largely unchanged.
• 1997-2001: A significant refresh occurred in 1997. This included a redesigned interior, new door skins, a revised tailgate, and updated exterior styling. Mechanical changes were less dramatic, but improvements were made to the 4.0L engine and cooling system. The airbag system was updated.

Reliability & Common Issues

The XJ Cherokee is generally considered a reliable vehicle, but like any older car, it has its share of potential problems. Proper maintenance is key to ensuring longevity.

Engines

• 2.5L AMC Inline-Four: Underpowered for the vehicle's weight, prone to head gasket issues. Not recommended.
• 2.8L GM V6: Known for reliability issues and lower power compared to the inline-six. Also, parts availability can be problematic. Avoid.
• 4.0L AMC/Chrysler Inline-Six: This is the engine to look for. It's durable, powerful, and relatively easy to work on. However, it can suffer from exhaust manifold cracks (especially pre-1999) and occasional oil leaks. Cooling system maintenance is critical to prevent overheating.

Transmissions

• Aisin-Warner AW4 Automatic: Very reliable if properly maintained. Fluid changes are crucial for long life.
• Peugeot BA10/5 5-Speed Manual (1984-1986): Known for being weak and prone to failure. Avoid if possible.
• AX-15 5-Speed Manual (1987-2000): A much more robust manual transmission. Still, check for smooth shifting and any unusual noises.

Transfer Cases

• NP207: Used in early models, not as strong as later transfer cases.
• NP231: The most common and generally reliable transfer case. Check for chain stretch and smooth engagement of 4WD.
• NP242 (Selec-Trac): Offers full-time 4WD in addition to part-time and 2WD modes. More complex than the NP231, so proper maintenance is even more important.

Axles

• Dana 30 Front Axle: Generally robust for moderate off-roading. Weak point is the vacuum disconnect on some early models (easily converted to a solid axle).
• Dana 35 Rear Axle: The weaker of the rear axle options, especially on models with larger tires. Prone to breakage under heavy stress.
• Chrysler 8.25" Rear Axle: A stronger alternative to the Dana 35. Look for this on later models, especially those with the Up Country suspension package.
• Dana 44 Rear Axle: Rare, but the strongest factory rear axle. Often found in models with the towing package.

Other Common Issues

• Rust: A major concern, especially in areas with road salt. Check the floorboards, rocker panels, frame rails, and around the windshield.
• Electrical Problems: Wiring harnesses can become brittle with age, leading to intermittent electrical issues. The Renix-era (pre-1991) engine management system can be challenging to diagnose and repair.
• Cooling System: Prone to overheating, especially the 4.0L engine. Regular coolant flushes, radiator replacements, and thermostat maintenance are essential.
• Sagging Leaf Springs: Common issue on older XJs, leading to a lower ride height and reduced off-road capability.
• Headliner Sagging: Another common cosmetic issue.
• "Death Wobble": A violent shaking of the front end at highway speeds, often caused by worn suspension components or improper alignment. Address immediately.

Driving Experience

The XJ Cherokee offers a unique driving experience that blends classic SUV characteristics with a surprising level of comfort. It's not as refined as modern SUVs, but it has a charm and capability that are hard to find elsewhere.

Pros

• Off-Road Capability: Excellent off-road performance, especially with the 4.0L engine and a capable 4WD system.
• Simple and Robust: Relatively easy to work on, with a large aftermarket parts availability.
• Compact Size: Easy to maneuver in tight spaces.
• Affordable: Still relatively inexpensive to buy, especially compared to newer SUVs.
• Iconic Design: Classic and timeless design that appeals to many.

Cons

• Fuel Economy: Not great, especially with the 4.0L engine.
• Ride Quality: Can be rough and bumpy on paved roads.
• Safety: Older models lack modern safety features like side airbags and stability control.
• Rust: A significant concern in many areas.
• Interior: Spartan and dated, especially in early models.

Buying Advice

When buying an XJ Cherokee, consider the following:

Years to Look For

• 1997-2001: These models offer the updated interior and exterior styling, along with some improvements to the 4.0L engine and cooling system. 1999-2001 are often considered the most desirable for their refinements.
• 1991-1996 (with 4.0L): A good balance of reliability and affordability. Avoid early Renix-era models (pre-1991) if you're not comfortable with older engine management systems.

Years to Avoid (or be cautious of)

• Early models (1984-1986): Prone to rust, less powerful engines, and the weak Peugeot BA10/5 manual transmission.
• Models with the 2.5L engine: Underpowered and less reliable.
• Models with excessive rust: Can be costly to repair and may compromise the structural integrity of the vehicle.

Key Things to Check

• Rust: Thoroughly inspect the entire vehicle for rust, paying close attention to the common areas mentioned above.
• Engine: Check for oil leaks, coolant leaks, and any unusual noises. Test drive the vehicle to ensure the engine runs smoothly and has adequate power.
• Transmission: Check for smooth shifting and any unusual noises. Ensure the transmission engages properly in all gears.
• 4WD System: Test the 4WD system to ensure it engages and disengages properly. Listen for any grinding noises or other issues.
• Suspension: Check for worn suspension components, such as ball joints, tie rod ends, and shocks. Look for sagging leaf springs.
• Electrical System: Test all electrical components, including the lights, wipers, radio, and power windows.
• Maintenance Records: Ask for maintenance records to get an idea of how well the vehicle has been cared for.

The Jeep Cherokee XJ remains a compelling choice for those seeking a capable, affordable, and iconic SUV. By carefully inspecting potential purchases and addressing any known issues, you can enjoy many years of reliable service from this classic off-roader.
