Why Focus on 1979 CJ5 Parts Specifically?

Reviving a Legend: A Deep Dive into 1979 Jeep CJ5 Parts

While many CJ5 parts are interchangeable across model years, the 1979 model year presents unique considerations. It falls within the later years of CJ5 production (1954-1983), meaning certain improvements and design changes had already been implemented. However, it also predates some of the more significant upgrades found in the final years of production. Understanding these nuances is crucial for sourcing the correct replacement parts and ensuring compatibility. Furthermore, focusing on the specific year helps filter out irrelevant information and provides a tailored approach to your CJ5 project.

1. The Engine Bay: Heart of the Beast

The 1979 CJ5 typically came with one of three engine options:

• 258 Cubic Inch Inline-Six (4.2L): This was the most common and arguably the most reliable engine option. Parts availability is excellent, making it a practical choice for restoration or maintenance. Expect to find a wide range of rebuild kits, gaskets, hoses, and performance upgrades.
• 304 Cubic Inch V8 (5.0L): A more powerful option that provided ample torque for off-road adventures. V8 parts are generally more expensive but still readily available. Common issues include carburetor problems and overheating, so focus on cooling system components.
• 151 Cubic Inch Inline-Four (2.5L): This engine was added later and provided better fuel economy but lacked the power of the other options.

Key Engine Parts and Considerations:

• Carburetor: The carburetor is a frequent source of problems. Consider rebuilding the original or upgrading to a more modern fuel injection system for improved performance and reliability. Carter BBD carburetors were common.
• Ignition System: Replacing the distributor, coil, and spark plugs with a high-performance ignition system can significantly improve engine performance. Look into electronic ignition conversions for increased reliability.
• Cooling System: The cooling system is crucial for preventing overheating, especially with the V8 engine. Replace the radiator, water pump, and hoses with high-quality replacements. Consider adding an electric fan for extra cooling in hot climates.

• Exhaust System: Replacing the exhaust manifold and exhaust system can improve engine performance and fuel economy. Aftermarket headers are a popular upgrade.

2. The Drivetrain: Power to the Wheels

The drivetrain of the 1979 CJ5 consisted of the transmission, transfer case, and axles. These components are responsible for transferring power from the engine to the wheels.

• Transmissions: The 1979 CJ5 typically came with either a T-150 three-speed manual transmission or a Turbo-Hydramatic 400 (TH400) three-speed automatic transmission.
• Transfer Case: The Dana 20 transfer case was standard. This is a robust and reliable unit, but wear and tear can occur over time.
• Axles: The front axle was typically a Dana 30, while the rear axle was either an AMC 20 or a Dana 44 (less common). The AMC 20 is known for its weak two-piece axle shafts, so upgrading to one-piece shafts is highly recommended, especially for serious off-roading.

Key Drivetrain Parts and Considerations:

• Clutch (for manual transmissions): Replacing the clutch disc, pressure plate, and throwout bearing is essential for maintaining smooth shifting.
• Transmission Rebuild Kits: If your transmission is slipping or making unusual noises, a rebuild kit can restore it to its original condition.
• Transfer Case Rebuild Kits: Similar to transmissions, transfer cases can also benefit from a rebuild.
• Axle Shafts: Upgrading the AMC 20 axle shafts to one-piece units is a common and worthwhile upgrade. Consider chromoly axle shafts for added strength.
• Gears: Re-gearing the axles can improve performance, especially if you've installed larger tires.

3. Suspension and Steering: Handling the Terrain

The suspension and steering systems are responsible for providing a comfortable ride and precise handling, both on and off-road.

• Suspension: The 1979 CJ5 used a leaf spring suspension system. While relatively simple, the leaf springs can sag over time, resulting in a rough ride.
• Steering: The steering system consisted of a steering box, tie rods, and drag link. The steering box can develop play over time, leading to sloppy steering.

Key Suspension and Steering Parts and Considerations:

• Leaf Springs: Replacing the leaf springs with new or aftermarket springs can improve ride quality and handling. Consider adding a lift kit for increased ground clearance.
• Shocks: Upgrading to high-performance shocks can further improve ride quality and handling.
• Steering Box: Rebuilding or replacing the steering box can eliminate play and restore precise steering.
• Tie Rods and Drag Link: Inspect these components for wear and tear. Replace them as needed to maintain proper steering alignment.
• Power Steering Conversion: If your CJ5 doesn't have power steering, converting to a power steering system can significantly improve driving ease, especially off-road.

4. Body and Interior: Restoring the Look and Feel

The body and interior are what give the CJ5 its distinctive look and feel. Restoring these components can transform a worn-out Jeep into a show-stopping classic.

• Body Panels: Body panels can rust over time, especially in areas with harsh weather conditions. Replacement body panels are available, but welding and bodywork may be required.
• Interior: The interior of the CJ5 is typically spartan, but it can be restored to its original condition with new seat covers, carpets, and dash components.

Key Body and Interior Parts and Considerations:

• Body Panels: Consider using rust-resistant coatings on replacement body panels to prevent future corrosion.
• Seat Covers: Replacing the seat covers can dramatically improve the look and feel of the interior.
• Carpets: New carpets can help to reduce noise and improve the overall comfort of the interior.
• Dash Components: Replacing cracked or faded dash components can restore the original look of the interior.
• Soft Top or Hard Top: A new soft top or hard top can provide protection from the elements.

5. Electrical System: Keeping the Lights On

The electrical system is responsible for powering the lights, gauges, and other electrical components.

• Wiring Harness: The wiring harness can become brittle and corroded over time, leading to electrical problems.
• Lights: Replacing the headlights, taillights, and turn signals with new or LED lights can improve visibility.
• Gauges: Replacing the gauges can ensure accurate readings of engine parameters.

Key Electrical Parts and Considerations:

• Wiring Harness: Consider replacing the entire wiring harness with a new or aftermarket harness to eliminate potential electrical problems.
• LED Lights: LED lights are brighter, more energy-efficient, and longer-lasting than traditional incandescent bulbs.
• Battery: Replacing the battery with a high-quality battery can ensure reliable starting.
• Alternator: Upgrading to a higher-output alternator can provide more power for accessories.

• Online Retailers: Numerous online retailers specialize in Jeep parts, offering a wide selection of new and used parts.
