These Jeeps are aging. While their build quality is generally robust, time takes its toll on every component. Rubber seals crack, metal rusts, and mechanical parts wear down. Using the correct 1987-1995 Jeep Wrangler Parts is paramount for several reasons:

• Safety: Worn-out brakes, suspension components, or steering parts can compromise your safety and the safety of others.
• Performance: Replacing worn components restores the Jeep's original performance and ensures optimal off-road capability.
• Reliability: Regular maintenance with quality parts prevents breakdowns and extends the lifespan of your YJ.
• Value: A well-maintained YJ with original or high-quality replacement parts retains its value and appeal.
• Preservation: Keeping these classic Jeeps on the road preserves a piece of automotive history.

Section 1: Understanding the YJ: Key Systems and Common Issues

Before diving into specific parts, it's essential to understand the major systems of the YJ and their common problems:

• Engine: The YJ was available with several engine options, including the 2.5L inline-four, the 4.2L inline-six (carbureted), and the 4.0L inline-six (fuel-injected). Common issues include oil leaks, vacuum leaks (especially on the carbureted 4.2L), and worn-out sensors (on fuel-injected models).
• Transmission: The YJ used both manual and automatic transmissions. Manual transmissions can suffer from worn synchronizers and clutch issues. Automatic transmissions can experience slipping and overheating.

• Transfer Case: The NP231 transfer case is common on the YJ. Problems can include chain stretch, worn bearings, and leaks.
• Axles: The YJ typically used Dana 30 front axles and Dana 35 or Dana 44 rear axles. Dana 35 axles are known to be weaker and prone to breakage under heavy off-road use. Common issues include worn ball joints, wheel bearings, and differential problems.
• Suspension: The YJ utilizes a leaf spring suspension. Common issues include sagging springs, worn bushings, and damaged shocks.
• Body: Rust is a major concern on YJs, especially in areas prone to moisture, such as the floor pans, rocker panels, and frame.
• Electrical: The YJ's electrical system can suffer from corroded connections, brittle wiring, and failing sensors.

Section 3: Finding the Right Parts: Sources and Considerations

Locating the correct 1987-1995 Jeep Wrangler Parts requires research and careful consideration of your needs and budget:

• Local Auto Parts Stores: Offer convenience and immediate availability, but may have limited selection for older vehicles.
• Online Retailers: Provide a vast selection of parts from various manufacturers at competitive prices. Examples include Quadratec, Morris 4x4 Center, and Amazon.
• Jeep Specialty Shops: Offer specialized knowledge and expertise, as well as a curated selection of high-quality parts.
• Used Parts: Salvage yards and online marketplaces (eBay, Craigslist) can be a source of affordable parts, but condition and reliability can be questionable.
• Original Equipment Manufacturer (OEM) Parts: Sourced directly from Jeep or their authorized suppliers. Offer the highest quality and fitment, but are typically the most expensive.
• Aftermarket Parts: Manufactured by companies other than Jeep. Can offer comparable quality at a lower price or provide performance upgrades.

Considerations When Choosing Parts:

• Quality: Prioritize quality over price, especially for critical components like brakes, suspension, and engine parts.
• Fitment: Ensure the parts are specifically designed for your YJ model year.
• Warranty: Check the warranty offered by the manufacturer or retailer.
• Reviews: Read online reviews to get feedback from other YJ owners.
• Your Needs: Consider your intended use for the Jeep. If you plan on serious off-roading, you'll need more durable and robust parts than if you primarily use it for commuting.

Section 4: Essential Maintenance and Upgrades: Practical Advice

• Regular Oil Changes: Use the correct oil viscosity and change it regularly (every 3,000-5,000 miles).
• Coolant Flush: Flush and replace the coolant every two years to prevent corrosion.
• Brake Inspection: Regularly inspect brake pads, rotors, and lines for wear and damage.
• Suspension Check: Check leaf springs, bushings, and shocks for wear and damage.
• Grease Fittings: Lubricate all grease fittings on the suspension and steering components.
• Rust Prevention: Apply rust inhibitor to exposed metal surfaces.

Popular Upgrades:

• Lift Kits: Improve off-road clearance and allow for larger tires.
• Tire Upgrades: Choose tires that are appropriate for your intended use.
• Bumper Upgrades: Add protection and mounting points for winches and other accessories.
• Winch: A must-have for serious off-roading.
• Lighting Upgrades: Improve visibility with LED headlights, taillights, and off-road lights.
• Disc Brake Conversion (Rear): Improve braking performance.
• Fuel Injection Conversion (for 4.2L): Improve reliability and performance.

Section 5: Common Challenges and Solutions

• Rust: The biggest challenge with YJs. Solution: Cut out rusted metal and weld in new panels, or apply rust inhibitors.
• Finding Discontinued Parts: Some parts are no longer manufactured. Solution: Search for used parts or explore aftermarket alternatives.
• Identifying the Correct Parts: YJs had numerous variations. Solution: Consult a parts catalog or VIN decoder to ensure you're ordering the right parts.
• Working on Older Vehicles: Can be challenging due to rusted bolts and worn components. Solution: Use penetrating oil, heat, and patience.

Section 6: Frequently Asked Questions (FAQ)

• Q: Where can I find a VIN decoder for my YJ?

  • A: Several online VIN decoders can provide information about your Jeep's original specifications.

• Q: What is the best way to deal with rust on my YJ?

  • A: The best approach depends on the severity of the rust. For minor surface rust, you can sand it down and apply a rust inhibitor. For more severe rust, you may need to cut out the rusted metal and weld in new panels.

• Q: What are the common engine options for the YJ?

  • A: The YJ was available with a 2.5L inline-four, a 4.2L inline-six (carbureted), and a 4.0L inline-six (fuel-injected).
