Why the 1991 Jeep Comanche? A Brief History and Enduring Appeal

1991 Jeep Comanche For Sale: Unearthing a Cult Classic

Introduced in 1986, the Jeep Comanche (MJ) was AMC’s bold attempt to blend the legendary capability of the Jeep Cherokee (XJ) with the practicality of a pickup truck. Built on the same unibody chassis as its SUV sibling, the Comanche offered a unique combination of ride comfort, agile handling, and off-road prowess not typically found in traditional body-on-frame trucks of its era. Its production run was relatively short, ending in 1992, making pristine examples increasingly rare and sought after.

The 1991 model year holds particular significance. By this point, the Comanche had matured, benefiting from several refinements. Crucially, 1991 saw the widespread adoption of the High Output (H.O.) 4.0-liter inline-six engine, boasting 190 horsepower and 225 lb-ft of torque. This engine, renowned for its reliability and power, transformed the Comanche from a capable hauler into a genuinely spirited performer, both on and off the pavement. Its XJ Cherokee roots mean a vast aftermarket for parts and modifications, allowing owners to customize their Comanches for anything from overland adventures to daily driving. Its unibody construction provides a lighter, more rigid chassis than traditional trucks, contributing to its unique driving dynamics and making it a standout choice for enthusiasts who appreciate its blend of SUV comfort and pickup utility.

Key Features and Specifications of the 1991 Model

Understanding the specifics of the 1991 Jeep Comanche is crucial for any potential buyer. These trucks were available in various configurations, catering to different needs and budgets.

Engine:

• 4.0L High Output (H.O.) Inline-Six: The star of the show. This robust engine, identified by its multi-port fuel injection, delivers impressive power and torque, making the Comanche surprisingly quick for its size. It’s known for its longevity if properly maintained.
• Note: While rare, some very early production 1991 models might still have the older Renix 4.0L, but the H.O. is the standard for the year.

Transmissions:

• Manual: Aisin-Warner AX-15 (5-speed). A durable and popular choice for those seeking direct control and better fuel economy.
• Automatic: Aisin-Warner AW4 (4-speed). A highly reliable and smooth-shifting automatic, well-suited for daily driving and off-road crawling.

Drivetrain:

• 2WD (Two-Wheel Drive): Available for those prioritizing fuel economy and on-road performance.
• 4WD (Four-Wheel Drive): The more common and highly desired option, utilizing the robust NP231 (part-time) or NP242 (full-time) transfer cases, offering legendary Jeep off-road capability.

Bed Lengths:

• Short Bed (6-foot): More common and maneuverable.
• Long Bed (7-foot): Rarer, offering greater hauling capacity.

Trim Levels:

• Pioneer: A mid-range trim offering a balance of features and affordability.
• Sportruck: A more basic, work-oriented trim.
• Eliminator: The top-tier, sport-oriented trim, often featuring body-colored grilles, unique decals, and more interior amenities.
• Laredo: Another higher-end trim, often focused on comfort and appearance packages.

The variety in configurations means that finding the "perfect" 1991 Comanche requires knowing what you value most – be it off-road capability, hauling capacity, or interior comfort.

What to Look For When Buying a 1991 Jeep Comanche

Purchasing a vehicle that’s over 30 years old requires a keen eye and a thorough inspection. Here’s a detailed guide on what to prioritize:

1. Rust, Rust, Rust: This is the Comanche’s Achilles’ heel, especially given its unibody construction.

   • Frame Rails: Critically inspect the unibody "frame" rails from front to back, particularly near the steering box, control arm mounts, and rear leaf spring mounts. Extensive rust here can be a deal-breaker.
   • Floor Pans and Rocker Panels: Check under the carpet and along the exterior rockers.
   • Bed and Bed Supports: Pay attention to the bed floor, wheel wells, and the underside where the bed meets the cab.
   • Rear Quarter Panels: Rust often appears around the wheel arches.
   • Front Fenders and Doors: Common areas for corrosion.
   • Solution: Minor surface rust is manageable, but widespread or structural rust often requires expensive and skilled repair.

2. Engine (4.0L H.O.):

   • Oil Leaks: Common around the valve cover, oil pan, and rear main seal. While some weeping is typical, heavy leaks indicate neglect.
   • Cooling System: Check the radiator, hoses, and water pump for leaks. Ensure the engine doesn’t overheat during a test drive. A clean, green coolant indicates proper maintenance; rusty coolant is a red flag.
   • Noise: Listen for excessive valvetrain noise (tappets), knocking (rod bearings), or unusual sounds.
   • Maintenance: Ask for service records. Regular oil changes and cooling system flushes are vital.

3. Transmission and Drivetrain:

   • Manual (AX-15): Check for smooth shifts, especially into reverse and 1st gear. Listen for grinding or difficulty engaging gears.
   • Automatic (AW4): Ensure smooth shifts without harshness or slipping. Check the fluid level and color (should be reddish, not dark or burnt-smelling).
   • Transfer Case (NP231/NP242): Test all 4WD modes (2H, 4H, 4L) to ensure they engage smoothly without grinding or binding.
   • Axles: Listen for humming or clunking noises, especially when turning. Check for excessive play in U-joints and axle shafts.

4. Suspension and Steering:

   • Steering Play: Excessive play in the steering wheel indicates worn steering box, tie rod ends, or ball joints.
   • Bushings: Inspect control arm bushings (front and rear), leaf spring bushings, and sway bar bushings for cracks or deterioration.
   • Shocks: Look for leaks. Bounce each corner of the truck to check for excessive rebound.

5. Electrical System:

   • Test all lights (interior and exterior), gauges, power windows (if equipped), HVAC fan, and radio.
   • Check for any warning lights on the dashboard.

6. Interior:

   • Assess the condition of seats, dashboard (cracks are common), headliner, and carpets. While cosmetic, these can indicate overall care.

7. Documentation:

   • Always request a clean title.
   • Service records provide invaluable insight into the vehicle’s history and maintenance.

Common Challenges and Solutions

Owning a vintage vehicle like the 1991 Jeep Comanche comes with its unique set of challenges, but most have practical solutions.

• Parts Availability: While many mechanical parts are shared with the ubiquitous XJ Cherokee, specific body panels, bed components, and some interior pieces for the Comanche can be difficult to source.
  • Solution: Join Comanche owner forums and Facebook groups. Enthusiasts often know where to find rare parts, or they may have spare parts themselves. Aftermarket reproduction parts are also becoming more available for some items.
• Rust Repair: As mentioned, rust is a major concern. Professional rust repair can be very costly, potentially exceeding the vehicle’s value.
  • Solution: For minor rust, DIY repair is possible. For structural issues, seek quotes from specialized body shops. Sometimes, finding a rust-free donor body is a more economical solution than extensive repair.
• Aging Components: Rubber hoses, seals, electrical wiring, and vacuum lines will inevitably degrade over time, leading to minor issues.
  • Solution: Proactive replacement of common wear items (e.g., cooling system overhaul, vacuum line replacement) can prevent future breakdowns. A good quality multi-meter and a factory service manual are invaluable for diagnosing electrical issues.
• Fuel Economy: The 4.0L H.O. engine, while powerful, isn’t known for stellar fuel efficiency, especially in 4WD models.
  • Solution: Regular maintenance, ensuring the engine runs optimally, can help. Modifications like larger tires or lift kits will further decrease MPG. Embrace it as part of the classic truck experience.

Tips for a Successful Purchase

1. Do Your Homework: Research market values, common issues, and different configurations.
2. Pre-Purchase Inspection (PPI): If you’re not mechanically inclined, pay a trusted independent mechanic specializing in Jeeps or classic vehicles to perform a thorough inspection. This small investment can save you thousands.
3. Test Drive Thoroughly: Drive on various road types (city, highway, rough roads) and test all features, including 4WD (if applicable). Listen for unusual noises, feel for vibrations, and check steering and braking performance.
4. Be Patient: Finding the right 1991 Comanche in good condition can take time. Don’t rush into a purchase.
5. Budget for the Unexpected: Even the best-maintained vintage vehicles will require ongoing maintenance and occasional repairs. Factor this into your overall budget. Consider whether you want a turn-key driver or a project truck.
