Reviving a Legend: A Comprehensive Guide to 1986 Jeep CJ7 Parts
While the CJ7 enjoyed a long production run (1976-1986), the 1986 model year represents the last and arguably the most refined version of this legendary Jeep. It benefits from advancements made throughout the CJ7's lifespan, offering a unique blend of classic styling and improved functionality. However, this also means that some parts are specific to this year, requiring careful attention when sourcing replacements or upgrades. This guide will help you navigate the nuances of 1986 CJ7 parts, ensuring you get the right fit and performance for your Jeep.
I. Understanding Your 1986 CJ7: A System-by-System Breakdown
Before diving into specific parts, it's crucial to understand the major systems within your 1986 CJ7. This will help you diagnose problems, identify the correct components, and plan your restoration or upgrade projects more effectively.
-
Engine: The 1986 CJ7 offered a range of engine options, most commonly the 2.5L (150 cu in) AMC inline-four, the 4.2L (258 cu in) AMC inline-six, and, less frequently, a 5.0L (304 cu in) V8. Understanding which engine your CJ7 has is paramount, as parts are engine-specific. Key components include the carburetor (or fuel injection system, if modified), distributor, starter, alternator, water pump, and exhaust manifold.
Transmission: The CJ7 typically came with a manual transmission (T-4, T-5, or T-176) or an automatic transmission (TorqueFlite 999). Transmission parts include gears, synchros, bearings, clutches, and torque converters. Knowing your transmission type is critical for sourcing the correct replacement parts.
-
Transfer Case: The transfer case is responsible for transferring power to the front and rear axles, enabling four-wheel drive. The Dana 300 transfer case was standard on the 1986 CJ7. Key components include gears, chains, and seals.
-
Axles: The CJ7 typically used a Dana 30 front axle and an AMC 20 rear axle (although some early 1986 models might have a Dana 44 rear). Axle parts include gears, bearings, shafts, and differentials. Understanding your axle ratio is important for maintaining performance and fuel economy.
-
Suspension: The CJ7 features a leaf spring suspension system. Key components include leaf springs, shocks, shackles, and bushings. Suspension parts play a crucial role in ride quality and off-road capability.
-
Brakes: The CJ7 typically used front disc brakes and rear drum brakes. Brake parts include rotors, calipers, pads, shoes, drums, master cylinder, and brake lines. Maintaining a reliable braking system is essential for safety.
-
Steering: The CJ7 used a power steering system. Key components include the power steering pump, steering gear box, steering shaft, and tie rod ends.
-
Body: The CJ7's body consists of the tub, fenders, hood, grille, and windshield. Body parts are often subject to rust and damage, making replacements a common need.
-
Electrical: The CJ7's electrical system includes the battery, alternator, starter, wiring harness, lights, and gauges. Electrical problems can be frustrating, so a thorough understanding of the system is helpful.
II. Sourcing 1986 CJ7 Parts: Where to Find What You Need
Finding the right parts for your 1986 CJ7 requires a strategic approach. Here's a breakdown of common sourcing options:
-
Online Retailers: Websites like Quadratec, Morris 4x4 Center, and Summit Racing offer a vast selection of CJ7 parts, including reproduction parts, aftermarket upgrades, and some NOS (New Old Stock) components. Online retailers often provide detailed product descriptions and customer reviews.
-
Local Auto Parts Stores: While local auto parts stores may not stock everything for a 1986 CJ7, they can often source common replacement parts like brake pads, rotors, filters, and belts.
-
Jeep Salvage Yards: Salvage yards specializing in Jeeps are a treasure trove of used parts. You can often find hard-to-find components at a fraction of the cost of new parts. Be prepared to inspect the parts carefully for wear and tear.
-
Online Marketplaces (eBay, Craigslist, Facebook Marketplace): These platforms can be a great source for both new and used CJ7 parts. However, exercise caution and thoroughly vet the seller before making a purchase.
-
Jeep Forums and Clubs: Online Jeep forums and local Jeep clubs are valuable resources for finding parts and connecting with other CJ7 enthusiasts who may have parts to sell or know where to find them.
Tips for Sourcing Parts:
- Know Your VIN: The Vehicle Identification Number (VIN) is crucial for identifying your CJ7's specific configuration and ensuring you get the correct parts.
- Compare Prices: Don't settle for the first price you see. Shop around and compare prices from different vendors.
- Read Reviews: Before purchasing a part, read customer reviews to get an idea of its quality and performance.
- Check Return Policies: Ensure the vendor has a reasonable return policy in case the part doesn't fit or is defective.
- Consider Aftermarket Upgrades: While maintaining originality is important for some, aftermarket upgrades can often improve performance, reliability, and safety.
III. Common 1986 CJ7 Parts and Considerations
This section highlights some commonly replaced parts on a 1986 CJ7 and provides specific considerations for each:
-
Leaf Springs: CJ7 leaf springs are prone to sagging and wear over time. When replacing them, consider the desired ride height and load capacity. Aftermarket leaf springs offer various options, including lift kits for increased ground clearance.
-
Shocks: Worn shocks can significantly impact ride quality and handling. Choose shocks that are appropriate for your driving style and the type of terrain you typically encounter.

Body Panels (Fenders, Rockers, Floors): Rust is a common problem on CJ7s, particularly in areas exposed to moisture and salt. Replacing rusted body panels can be a major undertaking, but it's essential for restoring the Jeep's structural integrity and appearance.

Soft Top/Hard Top: The CJ7's soft top is often the first thing to wear out. Replacement soft tops are available in various materials and styles. Hard tops offer increased weather protection and security.
-
Seats: CJ7 seats can become worn and uncomfortable over time. Replacement seats are available in various styles and materials, including aftermarket seats that offer improved comfort and support.

Carburetor (if applicable): The Carter BBD carburetor on the 4.2L inline-six is known for its complexity and potential for problems. Many owners opt to replace it with a more reliable aftermarket carburetor or a fuel injection system.
-
Wiring Harness: The CJ7's wiring harness can become brittle and corroded over time, leading to electrical problems. Replacing the entire wiring harness is a significant undertaking but can resolve many electrical issues.
