The 1972 Jeep Commando is a rugged and distinctive vehicle, a testament to Jeep's legacy of off-road capability and unique styling. For enthusiasts looking to restore or maintain their '72 Commando, understanding the availability, sourcing, and nuances of its specific parts is crucial. This article serves as a comprehensive guide, covering everything from common replacement parts to rarer finds, offering practical advice and insights to help you keep your Commando running strong.
Introduction: The Allure of the '72 Jeep Commando
Restoring a Classic: A Deep Dive into 1972 Jeep Commando Parts
The Jeep Commando, produced from 1966 to 1973, was a unique attempt by Jeep to compete with the growing SUV market. The 1972 model year is particularly interesting because it sits firmly within the second generation (1972-1973) which saw a significant redesign of the front end. Unlike the earlier "flat-fendered" Commandos, the '72 features a more conventional, squared-off grille, giving it a distinct and arguably more modern appearance. This redesign, while controversial among purists, broadened the Commando's appeal and makes the '72 model a sought-after classic for many Jeep enthusiasts.
Restoring a '72 Commando is more than just fixing a vehicle; it's preserving a piece of automotive history. However, sourcing parts for a vehicle of this age can present unique challenges. This guide aims to demystify that process, providing the knowledge needed to tackle your Commando project with confidence.
Section 1: Essential Engine and Drivetrain Parts
The heart of any Commando is its engine and drivetrain. The '72 Commando typically came with one of two engine options: the Buick 225 cubic inch "Dauntless" V6 or the AMC 304 cubic inch V8. Understanding which engine you have is the first step in sourcing the correct parts.
- Engine Components: Common replacement parts include spark plugs, ignition coils, distributor caps, rotors, fuel pumps, water pumps, and thermostats. Finding these parts is generally straightforward, as many aftermarket options exist. However, ensuring compatibility with the specific engine (V6 or V8) is paramount.
- Drivetrain: The '72 Commando usually came with a three-speed manual or a three-speed automatic transmission (Turbo Hydramatic 400 with the V8). Parts like clutch kits (for manual transmissions), torque converters (for automatics), and transmission seals are frequently needed. The transfer case (Dana 20) is another critical component, requiring regular maintenance and potential replacement of seals and bearings.
- Axles: The Dana 30 front axle and Dana 44 rear axle were standard. Replacing worn bearings, seals, and brake components (drums, shoes, wheel cylinders) is essential for safe operation. Upgrading to stronger axles or adding locking differentials are common modifications for off-road enthusiasts.
Tip: When ordering engine or drivetrain parts, always double-check the engine code or VIN to ensure compatibility. Many online retailers offer compatibility charts or search functions.
Challenge: Finding original Buick V6 engine parts can sometimes be more challenging than sourcing parts for the AMC V8. Consider aftermarket performance upgrades or sourcing from specialized Jeep restoration shops.
Section 2: Body and Exterior Components
The '72 Commando's distinctive body style requires specific parts for restoration.
- Body Panels: Rust is a common enemy of older vehicles. Finding rust-free body panels can be difficult. Reproduction panels are available, but their quality can vary. Consider welding in patch panels if the original panels are only partially damaged. Common rust areas include the floor pans, rocker panels, and around the wheel wells.
- Grille and Trim: The '72 Commando's unique grille is a defining feature. Finding an original in good condition can be challenging. Reproduction grilles are available, but ensure they match the original dimensions and finish. Trim pieces, such as side moldings and emblems, can also be hard to find. Scouring online marketplaces and attending Jeep swap meets are good strategies.
- Glass: Windshields, side windows, and rear windows are usually easier to source, as reproduction glass is widely available.
- Soft Top/Hard Top: Depending on the original configuration, your Commando may have a soft top or a hard top. Soft tops will likely need replacement due to wear and tear. Hard tops can be repaired and repainted.
Practical Advice: When replacing body panels, take detailed photos of the original configuration before disassembly. This will help ensure proper alignment and fitment of the new panels.
Important Consideration: Consider the cost and availability of body parts when evaluating a Commando for purchase. Extensive body work can significantly increase the overall restoration cost.
Section 3: Interior Components and Electrical System
The interior and electrical system of a '72 Commando can present unique challenges.
- Upholstery and Trim: Original upholstery is likely to be worn or damaged. Reproduction upholstery kits are available, but consider having a professional install them for the best results. Replacing carpets, headliners, and door panels can significantly improve the interior appearance.
- Gauges and Instruments: The gauges in a '72 Commando are often prone to failure. Finding replacements can be difficult. Consider sending them to a specialized gauge repair shop for restoration.
- Wiring Harness: A faulty wiring harness can cause numerous electrical problems. Reproduction wiring harnesses are available, but installing them can be a complex task. Labeling the wires during removal is essential for proper reinstallation.
- Lighting: Headlights, taillights, and turn signals are relatively easy to replace. Consider upgrading to LED lighting for improved visibility and reliability.
How-To Guide: Replacing a Faulty Wiper Motor
- Disconnect the battery's negative terminal.
- Locate the wiper motor (typically under the dashboard).
- Disconnect the wiring harness from the wiper motor.
- Remove the mounting screws that secure the wiper motor to the firewall.
- Remove the wiper motor linkage from the motor arm.
- Install the new wiper motor, reversing the above steps.
Potential Challenge: Electrical problems can be difficult to diagnose. Consider consulting a qualified mechanic or using a multimeter to troubleshoot electrical circuits.
Section 4: Suspension and Brakes
Maintaining a safe and reliable ride requires attention to the suspension and brakes.
- Suspension: Replacing worn shocks, leaf springs, and bushings is essential for restoring the original ride quality. Consider upgrading to a lift kit for improved off-road performance.
- Brakes: Replacing brake lines, master cylinder, wheel cylinders, drums, and shoes is crucial for safe stopping. Consider upgrading to disc brakes for improved braking performance.
- Steering: Worn steering components, such as tie rod ends and ball joints, can cause steering issues. Replacing these components is essential for maintaining proper steering control.
Benefits: Upgrading the suspension and brakes can significantly improve the Commando's handling and safety.
Tips: When replacing brake lines, use a tubing bender to avoid kinking the lines. Always bleed the brakes after replacing any brake components.
Section 5: Where to Find '72 Jeep Commando Parts
Sourcing parts for a '72 Commando requires a combination of online research, local resources, and patience.
- Online Retailers: Several online retailers specialize in Jeep parts, including Quadratec, Morris 4x4 Center, and KaiserWillys.com. These retailers offer a wide selection of parts, from common maintenance items to rarer restoration parts.
- Online Marketplaces: eBay and Craigslist can be good sources for used or NOS (New Old Stock) parts. Be sure to carefully inspect the parts before purchasing them.
- Jeep Forums: Jeep forums are a valuable resource for finding parts and advice. Many forum members are willing to share their knowledge and experience.
- Local Auto Parts Stores: While local auto parts stores may not carry all the parts you need, they can often supply common maintenance items, such as spark plugs, filters, and brake components.
- Jeep Swap Meets: Attending Jeep swap meets is a great way to find rare or hard-to-find parts. You can also meet other Jeep enthusiasts and learn from their experiences.
