The Enduring Appeal of the 1987 Jeep Truck (Comanche MJ)

1987 Jeep Truck For Sale: A Comprehensive Guide to Finding Your Classic Comanche

The 1987 Jeep Truck, specifically the Comanche (MJ), represents a fascinating chapter in Jeep’s history. Launched in 1986, the Comanche was based on the successful unibody platform of the Jeep Cherokee (XJ), giving it a car-like ride and handling characteristics uncommon in traditional body-on-frame pickups of its era. This innovative design, combined with Jeep’s legendary off-road prowess, created a vehicle that was both comfortable for daily driving and incredibly capable when the pavement ended.

For 1987, the Comanche was in its early prime, offering a robust set of features and the nascent stages of what would become the revered 4.0L "Renix" inline-six engine. Its appeal today stems from several factors: its unique unibody construction, which provides a stiffer chassis and lighter weight; its distinctive styling that marries the iconic Cherokee front end with a versatile pickup bed; and its increasing rarity, making it a sought-after collector’s item. Unlike its larger J-series predecessors, the Comanche offered a more nimble and fuel-efficient package without sacrificing true Jeep capability. Whether for light hauling, off-road excursions, or simply as a nostalgic cruiser, the 1987 Jeep Truck stands out as a practical classic with undeniable character.

Key Features and Specifications of the 1987 Jeep Comanche

Understanding the core attributes of the 1987 Jeep Truck is crucial for any prospective buyer. The Comanche was offered with a variety of configurations that directly impact its performance, utility, and desirability.

• Engine Options:

  
  • 2.5L AMC I4 (117 hp): The standard engine, offering decent fuel economy but less power for heavier loads or spirited driving.
  • 4.0L AMC I6 "Renix" (173 hp): The highly coveted engine, sharing its lineage with the legendary Cherokee XJ. This inline-six is known for its torque, reliability (once certain quirks are addressed), and strong performance, making it the preferred choice for most enthusiasts.
  • Note: A 2.1L Renault turbodiesel was also offered in some markets, but it’s exceptionally rare in North America.



• Transmission Options:

  • Manual: A 4-speed or 5-speed manual transmission was available, offering direct control and ruggedness.
  • Automatic: A 4-speed automatic (AW4) transmission was optional, known for its durability.

  

• Drivetrain:

  • 2WD: Rear-wheel drive was standard, suitable for on-road use and lighter hauling.
  • 4WD (Command-Trac NP207/NP231 or Selec-Trac NP229): Jeep’s renowned four-wheel-drive systems provided serious off-road capability. The Command-Trac (part-time) was more common, while the Selec-Trac (full-time capable) offered added versatility.

• Body Styles: The Comanche was available with either a 6-foot (short bed) or 7-foot (long bed) cargo box, catering to different hauling needs. The long bed versions are less common and often command a premium for their increased utility.

• Trim Levels: Various trim levels influenced standard features and aesthetics, ranging from the basic "SporTruck" and "Pioneer" to the more upscale "Chief," "Laredo," and the sporty "Eliminator" (though the Eliminator package became more prominent in later years, some elements might be seen in 1987).

• Payload & Towing: Depending on the configuration, the 1987 Comanche could handle payloads from 1,400 to 2,200 lbs and tow between 2,000 to 5,000 lbs, making it a surprisingly capable compact truck.

What to Look For When Buying a 1987 Jeep Truck: An Inspection Guide

Purchasing a classic vehicle like the 1987 Jeep Truck requires diligence. Due to their age and often rugged lives, these vehicles can hide significant issues. A thorough inspection is paramount.

1. Rust: This is the #1 killer of older Jeeps. Inspect thoroughly:

   • Frame Rails: Especially where leaf springs mount, and near the transmission crossmember.
   • Bed Floor & Supports: Check underneath the bed and inside for holes or weak spots.
   • Rocker Panels & Cab Corners: Common areas for rust to form.
   • Fenders & Wheel Wells: Look for bubbling paint or perforations.
   • Floorboards: Check for soft spots or patch panels that might hide deeper issues.
   • Windshield Frame: Prone to rust, leading to leaks.

2. Engine (Renix 4.0L Specifics):

   • Maintenance History: Look for records of oil changes, coolant flushes, and tune-ups.
   • Oil Leaks: Common around the valve cover, oil pan, and rear main seal.
   • Cooling System: Check the radiator, hoses, and water pump for leaks or signs of neglect.
   • Renix System: The 1987 4.0L uses the "Renix" fuel injection system, known for its unique sensors and wiring. Ensure all sensors (CPS, TPS, MAP, O2) are functioning, and check for poor grounds, which can cause erratic running.
   • Exhaust Manifold: Prone to cracking. Listen for ticking noises.

3. Transmission & Drivetrain:

   • Manual: Check for smooth shifting, clutch engagement, and any grinding noises.
   • Automatic (AW4): Ensure smooth shifts without hesitation or slipping. Check fluid color and smell.
   • Transfer Case (NP207/NP231/NP229): Engage 4WD (high and low range) to ensure it shifts properly without grinding. Check for leaks.
   • Differentials & U-joints: Listen for clunking noises during acceleration or deceleration, indicating worn U-joints or differential issues.

4. Suspension & Steering:

   • Leaf Springs: Check for sagging, especially in the rear.
   • Shocks: Look for leaks or excessive bounce.
   • Bushings: Inspect all suspension bushings for cracks or wear.
   • Ball Joints & Tie Rods: Check for play in the front end.
   • Steering Box: Look for leaks or excessive play in the steering wheel.

5. Brakes: Check for worn pads/shoes, corroded lines, and proper pedal feel.

6. Electrical: Test all lights, gauges, HVAC controls, power windows (if equipped), and radio. Pay attention to any flickering or non-functional components.

7. Interior: Assess the condition of seats, dashboard, carpet, and headliner for rips, tears, cracks, or water damage.

8. Documentation: Request service records, receipts for parts, and a clear title. A detailed history indicates a cared-for vehicle.

Common Issues and Potential Solutions

Even a well-maintained 1987 Jeep Truck might present some age-related challenges:

• Renix System Peculiarities: The Renix 4.0L can be finicky. Common solutions include upgrading engine grounds, replacing the Crank Position Sensor (CPS), and ensuring all vacuum lines are intact. Many online resources and forums offer detailed troubleshooting guides.
• Rust Mitigation: If rust is present, assess if it’s surface rust (manageable with sanding and paint) or structural (requiring professional welding and panel replacement). Prevention is key for any rust-free examples.
• Sagging Rear Leaf Springs: Over time, the rear leaf springs can flatten, leading to a "saggy" rear end. Solutions include adding an "add-a-leaf," replacing the leaf packs, or converting to a coil spring suspension (more complex).
• Aging Rubber Components: Hoses, belts, weatherstripping, and bushings will inevitably degrade. These are generally inexpensive to replace and crucial for reliability.
• Parts Availability: While many mechanical parts are shared with the ubiquitous XJ Cherokee, specific body panels (e.g., bed, rear fenders) for the Comanche can be scarce. Aftermarket support for suspension and drivetrain components is excellent.
