The Enduring Appeal of the 1987 Jeep YJ

Why does the 1987 Jeep YJ continue to capture the imagination of off-roaders and collectors alike? As the inaugural year of the Wrangler line, the ’87 YJ carries a unique historical significance. It introduced the world to the "square headlight" design, a feature that, while initially controversial among purists, has become a defining and beloved characteristic of the YJ generation. Beyond aesthetics, the 1987 YJ offers a simpler, more analog driving experience compared to modern vehicles, appealing to those who appreciate mechanical robustness and hands-on maintenance. Its legendary off-road prowess, combined with a vast aftermarket for customization, ensures that a YJ can be tailored for anything from daily commuting to extreme rock crawling. It truly bridges the gap between the raw simplicity of the CJ and the more contemporary comforts of later Wranglers.

Key Specifications and Features of the ’87 YJ

Understanding the core components of the 1987 YJ is crucial for any prospective buyer. This model came with specific engine and transmission options, as well as distinct chassis characteristics:

• Engines:
  • 2.5L AMC Inline-4 (later "Iron Duke"): A more economical and simpler engine, offering decent power for lighter use and excellent fuel economy for a Jeep of its era.
  • 4.2L AMC Inline-6 (258 cu in): The more popular choice for its robust torque and better overall performance, especially for off-roading. However, it came equipped with a problematic Carter BBD carburetor that often required significant tuning or aftermarket replacement.

  

• Transmissions:
  • Manual: Primarily the Peugeot BA 10/5 five-speed manual, which is known to be a weak point and often gets swapped out for the stronger AX-15 (introduced later in the YJ run) or other heavy-duty transmissions.
  • Automatic: The reliable Torqueflite 904 (for 2.5L) or TF999 (for 4.2L) three-speed automatic.

  

• Transfer Case: The Command-Trac NP207, offering part-time 4WD with high and low range.
• Suspension: Leaf springs on all four corners, a departure from the CJ’s narrower stance, giving the YJ improved stability on-road.
• Axles: Typically a Dana 30 in the front and a Dana 35 in the rear, which are adequate for most uses but often upgraded for serious off-roading.
• Distinctive Features: The most notable are the rectangular headlights, wider grille, and a slightly wider track than the CJ, enhancing stability. The interior was also a bit more refined, though still basic by modern standards.

Navigating the Purchase: What to Inspect on a 1987 YJ

When considering a 1987 Jeep YJ for sale, a thorough inspection is paramount. These vehicles are over 35 years old, and their condition can vary wildly.

• Rust is King: This is the absolute first thing to inspect. Jeeps of this era are highly susceptible to rust.
  • Frame: Pay close attention to the frame rails, especially near the skid plate mounts, spring shackles, and the rear crossmember. Look for deep pitting, flaking, or previous patch jobs.
  • Body Tub: Check the floorboards (especially under the carpets), wheel wells, rocker panels, door sills, and the area around the roll bar mounts.
  • Fenders and Grille: These areas also commonly show rust.
• Mechanical Health:
  • Engine: Listen for knocking, ticking, or excessive smoke. Check for oil and coolant leaks. If it’s a 4.2L, ask about carburetor history – a "Nutter Bypass" or TBI conversion is a huge plus.
  • Transmission and Transfer Case: Test all gears in both 2WD and 4WD (high and low). Listen for grinding or difficulty shifting. Check fluid levels and condition.
  • Axles: Look for fluid leaks around the differentials and listen for unusual noises during a test drive, which could indicate worn bearings.
  • Suspension: Inspect leaf springs for sagging (a common issue), broken leaves, worn bushings, and cracked shackle mounts. Check shocks for leaks.
  • Steering: Excessive play in the steering wheel, wander, or clunking sounds can indicate worn tie rods, ball joints, or a tired steering box.
  • Brakes: Ensure the pedal feels firm and the Jeep stops straight. Inspect brake lines for corrosion.
• Electrical System: Test all lights, gauges, wipers, and the heater/AC (if equipped). YJs can have some electrical quirks.
• Modifications: Many YJs have been modified. Assess the quality of any lift kits, aftermarket bumpers, or engine upgrades. Poorly installed modifications can cause more problems than they solve. Look for professional welding and proper wiring.
• Documentation: A clean title is a must. Service records, receipts for parts, and a history of ownership can provide valuable insights into the vehicle’s past care.

Common Challenges and Solutions for ’87 YJ Owners

Owning a vintage Jeep comes with its own set of common challenges, but fortunately, most have well-established solutions:

• Carburetor Woes (4.2L): The original Carter BBD carburetor on the 4.2L engine is notoriously finicky.
  • Solution: The "Nutter Bypass" (a simple wiring modification) often improves performance. For a more significant upgrade, many owners convert to fuel injection using kits from companies like Howell, Holley Sniper, or Mopar MPFI. This vastly improves reliability, cold starts, and fuel economy.
• Peugeot BA 10/5 Transmission: This manual transmission is known for its fragility, especially under hard use or with larger tires.
  • Solution: The most common and recommended solution is to swap it out for the stronger Aisin AX-15 manual transmission (found in later YJs and TJs) or a heavy-duty automatic.
• Rust: As mentioned, rust is a persistent enemy.
  • Solution: Thorough inspection and professional repair are essential. For ongoing prevention, consider rust-proofing treatments and regular cleaning, especially if you live in a wet or snowy climate.
• Dana 35 Rear Axle: While adequate for light duty, the Dana 35 can be a weak link for aggressive off-roading, especially with larger tires.
  • Solution: Upgrading to a stronger axle, such as a Ford 8.8 or a Dana 44, is a common modification for serious off-road enthusiasts.

Valuation and Market Dynamics

The price of a 1987 Jeep YJ for sale can vary significantly based on several factors:

• Condition: This is the most crucial factor. A rust-free, well-maintained YJ will command a premium.
• Engine Type: YJs with the 4.2L engine are generally more desirable, especially if they have been converted to fuel injection.
• Transmission: Manual transmissions are often preferred by enthusiasts, but a solid automatic can also be appealing.
• Mileage: While lower mileage is always a plus, the overall condition and maintenance history are often more important than the odometer reading on a vehicle of this age.
• Modifications: High-quality, professionally installed modifications can add value, but poorly done "bubba" mods can detract from it.
• Location: Jeeps from dry, rust-free climates (e.g., Southwest US) will typically be more expensive due to their better condition.

Tips for a Successful Purchase Journey

• Set a Realistic Budget: Beyond the purchase price, factor in potential immediate repairs, maintenance, and any desired upgrades.
• Get a Pre-Purchase Inspection (PPI): Even if you’re mechanically inclined, having a trusted mechanic (preferably one familiar with older Jeeps) perform a PPI can uncover hidden issues.
• Thorough Test Drive: Drive the YJ on varying terrain if possible. Listen for strange noises, test the brakes, and ensure 4WD engages smoothly.
• Negotiate: Be prepared to negotiate, especially if you’ve identified areas needing repair.
• Understand the Commitment: Owning a vintage Jeep is a lifestyle. It requires patience, a willingness to learn, and often, a sense of humor. Parts are generally available, but you might spend time sourcing specific components.
