The ’88 Comanche’s Unique Place in Jeep Lore

The 1988 model year for the Comanche, often referred to by its factory designation MJ, sits at a pivotal point in its relatively short production run (1986-1992). It benefits from early refinements made to the pioneering unibody pickup concept while retaining the quintessential AMC-era Jeep charm before Chrysler’s full influence took hold. The MJ was essentially a pickup truck version of the wildly popular XJ Cherokee SUV, sharing much of its chassis, powertrain, and interior components. This commonality is a significant advantage for owners, as many parts remain readily available.

The core of the ’88 Comanche’s legendary status lies in its powertrain options. The most coveted is undoubtedly the 4.0-liter inline-six (I6) engine, specifically the "Renix" era version. This engine is renowned for its durability, torquey performance, and straightforward design, making it a favorite among off-roaders and daily drivers alike. While the 2.5-liter AMC four-cylinder was also offered, the 4.0L is the one that truly defines the Comanche’s rugged character.

Transmissions available in 1988 included the robust AX-15 5-speed manual and the equally durable AW4 4-speed automatic. Both are excellent choices, offering reliable power transfer to either the rear wheels (2WD) or all four wheels via Jeep’s Command-Trac (NP231) part-time 4WD transfer case. The ’88 Comanche also offered two bed lengths: a 6-foot "short bed" and a less common 7-foot "long bed," adding to its versatility.

Trim levels ranged from the basic Pioneer to the more upscale Laredo and the sporty Eliminator, each offering different aesthetic and comfort packages. Regardless of trim, the ’88 Comanche’s appeal stems from its unique unibody construction, which provides a more car-like ride quality than traditional body-on-frame trucks, while still delivering impressive payload and towing capacities for its size.

Essential Considerations When Evaluating an ’88 Jeep Comanche For Sale

Purchasing a vehicle that is over three decades old requires a discerning eye and a clear understanding of potential issues. Here are the key areas to focus on when you find an "88 Jeep Comanche for sale":

1. Rust: The Primary Concern: Given its age and the unibody construction, rust is the most critical factor. Thoroughly inspect:

   • Frame Rails: Especially near the rear leaf spring mounts and where the unibody transitions. Severe rust here can be a deal-breaker.
   • Floorboards and Rocker Panels: Check under the carpets and along the vehicle’s sides.
   • Bed: Look for rust-through, particularly in the corners, drain holes, and under any bed liner.
   • Fenders and Doors: Common spots for bubbling paint or visible rust.
   • Cab Mounts: Ensure they are solid.

2. Engine Health (4.0L Renix Specifics): The 1988 4.0L engine utilizes the "Renix" fuel injection system, which is known for its reliability but also for specific quirks:

   • Ground Issues: The Renix system is sensitive to poor electrical grounds. Check for rough idle, stalling, or intermittent sensor readings. Often, simply cleaning or adding new ground straps can resolve many issues.
   • Sensor Health: Pay attention to the Throttle Position Sensor (TPS), Crankshaft Position Sensor (CPS), and Oxygen Sensor (O2). Failures can lead to poor performance or no-start conditions.
   • Oil Leaks: Common culprits include the valve cover gasket and rear main seal. While the latter can be a big job, it’s a known issue for the 4.0L.
   • Cooling System: Check the radiator, water pump, and hoses for leaks or signs of neglect. Overheating is detrimental to any engine.

3. Transmission and Drivetrain:

   • Manual (AX-15): Test all gears for smooth engagement and listen for grinding. Clutch feel should be consistent.
   • Automatic (AW4): Shifts should be firm but smooth, without slipping or harsh clunks. Check fluid color (should be reddish, not dark or burnt).
   • Transfer Case (NP231): For 4WD models, ensure it shifts easily into 2WD, 4-High, and 4-Low. Listen for grinding or binding noises.
   • Axles and Driveshafts: Inspect U-joints for play and listen for clunking during acceleration or deceleration, which could indicate worn differential components.

4. Suspension and Steering:

   • Sagging Rear Springs: Almost all MJs will have some degree of rear leaf spring sag due to age and payload. This is a common and relatively easy fix, but factor it into your budget.
   • Steering Play: Excessive looseness in the steering wheel could point to a worn steering box, tie rod ends, or ball joints.
   • Shocks: Look for leaks or a bouncy ride, indicating worn shocks.

5. Interior and Electrical Systems:

   • Dashboard Cracks: Very common due to sun exposure.
   • Electrical Gremlins: Test all lights (interior and exterior), gauges, power windows, locks, and the HVAC system. Aged wiring can lead to various intermittent issues.
   • Seats: Check for tears, wear, and proper adjustment.

Practical Advice for Buying an ’88 Jeep Comanche

• Bring a Magnet: A simple refrigerator magnet can help detect body filler over rust spots. If it doesn’t stick, there’s filler.
• Cold Start: Always try to inspect the vehicle when the engine is cold to observe its cold-start characteristics and listen for any abnormal noises.
• Test Drive: Drive it on various surfaces – highway, city, and if possible, some uneven terrain for 4WD models. Pay attention to how it handles, brakes, and accelerates.
• Check Documentation: Verify the VIN on the vehicle matches the title. Ask for any maintenance records; a well-documented history is a huge plus.
• Budget for the Unexpected: Even the best-inspected ’88 Comanche will likely need some attention. Set aside funds for immediate maintenance (fluids, filters, spark plugs) and potential repairs.
• Join the Community: Before, during, and after your purchase, engage with online forums like ComancheClub.com or dedicated Facebook groups. The collective knowledge of MJ owners is an invaluable resource for troubleshooting, parts sourcing, and general advice.

The Comanche Community and Future Outlook

The ’88 Jeep Comanche, much like its XJ Cherokee sibling, benefits from an incredibly strong and passionate enthusiast community. This means access to a wealth of knowledge, aftermarket parts, and even hard-to-find used components. As a classic vehicle, the Comanche’s value has been steadily appreciating, especially for well-preserved or expertly restored examples. Its unique status as the last unibody pickup truck makes it a significant piece of automotive history.

Whether you’re looking for a reliable daily driver, a capable off-road rig, or a restoration project, an "88 Jeep Comanche for sale" offers a truly unique ownership experience.
