But like any vehicle of its age, maintaining and restoring a 1987 Jeep Wrangler requires a dedicated understanding of its specific parts. This guide dives deep into the world of '87 Jeep parts, providing you with the knowledge and resources to keep your YJ running strong and looking its best.
Why Focus on 1987 Jeep Wrangler (YJ) Parts?
Reviving a Legend: A Comprehensive Guide to 1987 Jeep Wrangler (YJ) Parts
While many parts are interchangeable across the YJ generation (1987-1995), there are key differences that make understanding the specifics of the 1987 model crucial. The '87 YJ was a transition year, featuring components that were unique or only shared with a few other model years. Knowing these nuances can save you time, money, and frustration when sourcing replacement or upgrade parts. Furthermore, focusing on the original specifications allows you to maintain the vehicle's historical accuracy and potential collectibility.
1. Engine Components: Keeping the Heart Pumping
The 1987 Jeep Wrangler YJ primarily came with two engine options:
- 2.5L AMC Inline-4: This engine, while not a powerhouse, offered decent fuel economy and reliability. Common issues include carburetor problems (if equipped), distributor wear, and gasket leaks.
- 4.2L AMC Inline-6: This larger engine provided more power and torque, making it a popular choice for off-roading. Common issues include carburetor complexities, vacuum leaks, and exhaust manifold cracking.
Parts Considerations:
- Carburetor: Rebuilding or replacing the carburetor is a common task. Ensure you order the correct carburetor for your engine and emissions configuration. Look for kits that include all necessary gaskets and jets.
- Distributor: Check for wear on the distributor cap, rotor, and ignition module. Upgrading to an electronic ignition system can improve reliability and performance.
- Water Pump: A failing water pump can lead to overheating. Replace it preventatively if it shows signs of leaks or noise.
- Radiator: Ensure the radiator is free of corrosion and leaks. Upgrading to a larger capacity radiator can be beneficial for off-roading or hot climates.
- Exhaust System: Inspect the exhaust manifold for cracks and leaks. Replacing the entire exhaust system with a performance upgrade can improve horsepower and sound.
- Engine Mounts: These can deteriorate over time, leading to excessive engine vibration. Replace them with durable rubber or polyurethane mounts.
Practical Advice: When sourcing engine parts, consider purchasing from reputable suppliers that offer warranties and technical support. Always double-check the part number against your vehicle's VIN to ensure compatibility.
2. Transmission and Drivetrain: Transferring Power to the Wheels
The 1987 Jeep Wrangler YJ typically came with either a manual or automatic transmission, depending on the engine and trim level. The transfer case, responsible for engaging four-wheel drive, is a critical component for off-road capability.
Parts Considerations:
- Transmission: Manual transmissions may require clutch replacements over time. Automatic transmissions may need fluid changes and filter replacements.
- Transfer Case: Check for leaks around the seals. A worn chain inside the transfer case can cause noise and reduced performance.
- Driveshafts: Inspect the U-joints for wear and play. Grease them regularly to prolong their lifespan.
- Axles: Check for bent axles or worn axle bearings. Upgrading to stronger axles is a common modification for serious off-roaders.
- Differentials: Inspect the differential gears for wear and damage. Rebuilding or replacing the differential can improve traction and performance.
How-To Guide: Replacing U-Joints:
- Gather your tools: Hammer, punch, sockets, wrenches, vise, U-joint press (optional).
- Remove the driveshaft: Disconnect the driveshaft from the axles and transmission/transfer case.
- Secure the driveshaft: Place the driveshaft in a vise.
- Remove the old U-joints: Use a hammer and punch (or a U-joint press) to drive out the old U-joints.
- Install the new U-joints: Carefully install the new U-joints, ensuring they are properly seated and lubricated.
- Reinstall the driveshaft: Reconnect the driveshaft to the axles and transmission/transfer case.
Important Considerations: When working on the drivetrain, use proper safety precautions, such as wearing gloves and eye protection. Consult a repair manual or online resources for specific instructions for your vehicle.
3. Suspension and Steering: Handling the Rough Stuff
The 1987 Jeep Wrangler YJ features a leaf spring suspension, known for its durability and simplicity. The steering system is typically a recirculating ball type.
Parts Considerations:
- Leaf Springs: Leaf springs can sag over time, reducing ride height and performance. Replacing them with new or upgraded springs can improve handling and off-road capability.
- Shock Absorbers: Worn shock absorbers can lead to a bouncy ride and reduced control. Replacing them with high-quality shocks can improve ride quality and handling.
- Steering Gearbox: Check for play in the steering gearbox. Adjusting or replacing the gearbox can improve steering response.
- Tie Rods and Ball Joints: Inspect these components for wear and play. Replacing them is essential for maintaining proper steering alignment.
- Sway Bar Links: These can break or wear out, leading to excessive body roll. Replacing them with stronger links can improve handling.
Tips: Consider upgrading to a lift kit to increase ground clearance and accommodate larger tires. Ensure the lift kit is compatible with your vehicle and driving style.
4. Body and Exterior: Preserving the Classic Look
The body of the 1987 Jeep Wrangler YJ is prone to rust, especially in areas exposed to salt and moisture. Maintaining the body and exterior is essential for preserving the vehicle's value and appearance.
Parts Considerations:
- Body Panels: Replace rusted or damaged body panels with new or used parts.
- Fenders: Check for rust around the wheel wells.
- Hood: Inspect the hood for dents and rust.
- Windshield Frame: This is a common area for rust. Replacing the windshield frame can improve visibility and safety.
- Soft Top or Hard Top: Replace worn or damaged tops to protect the interior from the elements.
- Bumpers: Upgrade to stronger bumpers for added protection.
Potential Challenges: Finding original or high-quality replacement body panels can be challenging. Consider using aftermarket parts that are designed to fit the 1987 Jeep Wrangler YJ.
5. Interior Components: Comfort and Functionality
The interior of the 1987 Jeep Wrangler YJ is relatively simple, but it's important to maintain the seats, carpets, and dashboard to ensure comfort and functionality.
Parts Considerations:
- Seats: Replace worn or damaged seats with new or used seats.
- Carpets: Replace stained or torn carpets with new carpets.
- Dashboard: Check for cracks and damage. Replacing the dashboard can improve the appearance of the interior.
- Gauges: Ensure the gauges are functioning properly.
- Wiring Harness: Check for damaged or corroded wires.
6. Brakes and Wheels: Essential for Safety
The braking system is crucial for safe operation. The wheels and tires also play a significant role in handling and performance.
Parts Considerations:
- Brake Pads and Rotors: Replace worn brake pads and rotors regularly.
- Brake Calipers: Check for leaks and corrosion.
- Brake Lines: Inspect the brake lines for leaks and damage.
- Wheels: Upgrade to larger or stronger wheels for improved appearance and performance.
