Why Understanding 1990 Jeep Cherokee Parts Matters
Reviving a Legend: A Comprehensive Guide to 1990 Jeep Cherokee Parts
The 1990 Cherokee is now over three decades old. While its robust design contributes to its longevity, time inevitably takes its toll. Understanding the intricacies of its parts is crucial for:
- Maintaining Reliability: Replacing worn or damaged parts with quality replacements ensures your Cherokee continues to perform reliably, both on and off the road.
- Preserving Value: Properly maintained Cherokees, especially those in good condition, retain their value and can even appreciate over time. Using correct or upgraded parts contributes to this preservation.
- Ensuring Safety: Worn brakes, suspension components, or steering parts can compromise safety. Addressing these issues promptly with the right parts is paramount.
- Customization and Performance Enhancement: The Cherokee's simple design makes it a popular platform for customization. Understanding available parts allows you to tailor your Jeep to your specific needs and preferences.
I. Essential Engine and Drivetrain Parts
The engine and drivetrain are the heart and soul of any vehicle, and the 1990 Cherokee is no exception. Here's a breakdown of key parts and considerations:
- Engine Components:
- Engine Block & Internals: While a complete engine rebuild is a major undertaking, individual components like pistons, rings, bearings, and crankshafts might need replacement. Sourcing OEM (Original Equipment Manufacturer) or reputable aftermarket brands is crucial for longevity.
- Cylinder Head: Inspect for cracks, warping, and valve seat wear. Consider a remanufactured or upgraded cylinder head for improved performance.
- Fuel System: Fuel pumps, injectors, and fuel filters are vital for proper engine operation. Clogged or faulty components can lead to poor performance and starting issues.
- Ignition System: Distributor cap, rotor, spark plugs, and ignition coil. Maintaining a healthy ignition system is essential for efficient combustion. Consider upgrading to a performance ignition system for increased horsepower.
- Cooling System: Radiator, water pump, thermostat, and hoses. Overheating is a common issue in older vehicles. Regular maintenance and replacement of cooling system components are crucial.
- Transmission:
- Automatic Transmission: Filter, fluid, and valve body components. Regular fluid changes and filter replacements are essential for maintaining the transmission's health.
- Manual Transmission: Clutch kit (disc, pressure plate, throw-out bearing), and shifter components. A worn clutch can lead to slippage and difficulty shifting.
- Transfer Case:
- NP231 Transfer Case: Chain, seals, and shift motor. This transfer case is known for its durability, but wear and tear can occur over time.
- Axles and Differentials:
- Front and Rear Axle Shafts: U-joints, bearings, and seals. Damaged axle shafts can lead to vibrations and potential failure.
- Differentials: Gears, bearings, and limited-slip differentials. Upgrading to a limited-slip differential can improve off-road traction.
Practical Advice:
- Diagnosis First: Before replacing any parts, thoroughly diagnose the issue to ensure you're addressing the root cause.
- OEM vs. Aftermarket: Weigh the pros and cons of OEM and aftermarket parts. OEM parts offer guaranteed fit and quality, but aftermarket parts can sometimes provide better performance or value.
- Research Brands: Research different brands and read reviews before purchasing parts. Opt for reputable brands known for quality and reliability.
II. Suspension and Steering Components
The suspension and steering systems are crucial for handling and ride quality. Maintaining these systems is paramount for safety.
- Suspension:
- Leaf Springs (Rear): Sagging or broken leaf springs can negatively impact ride height and handling. Consider replacing with new leaf springs or adding an add-a-leaf kit.
- Coil Springs (Front): Similar to leaf springs, coil springs can sag over time. Replacing with new springs or adding spacers can restore ride height.
- Shocks and Struts: Worn shocks and struts can lead to a bouncy ride and reduced handling. Upgrading to performance shocks can improve both on and off-road performance.
- Control Arms: Bushings, ball joints, and control arm assemblies. Worn bushings and ball joints can cause steering play and vibrations.
- Steering:
- Steering Box: Over time, the steering box can develop play and leak fluid. Consider rebuilding or replacing the steering box.
- Tie Rods and Drag Link: These components connect the steering box to the wheels. Worn tie rod ends and drag links can cause steering play and instability.
- Power Steering Pump: A faulty power steering pump can make steering difficult.
How-To Tip: Replacing Leaf Springs
- Loosen Lug Nuts: Loosen the lug nuts on the rear wheels.
- Raise and Support: Jack up the rear of the Jeep and support it with jack stands.
- Disconnect Shocks: Disconnect the lower shock mounts.
- U-Bolts: Remove the U-bolts that hold the leaf spring to the axle.
- Leaf Spring Bolts: Remove the bolts that secure the leaf spring to the frame.
- Install New Spring: Install the new leaf spring in the reverse order.
Important Considerations:
- Lift Kits: If you plan to lift your Cherokee, you'll need to replace the suspension components with parts designed for the desired lift height.
- Alignment: After replacing any suspension or steering components, it's essential to have the vehicle professionally aligned.
III. Brakes and Wheels
Reliable braking is non-negotiable, and proper wheel maintenance contributes to overall safety and performance.
- Brakes:
- Brake Pads and Rotors: Replace worn brake pads and rotors regularly to ensure optimal braking performance.
- Brake Calipers: Inspect calipers for leaks and proper operation. Rebuild or replace calipers as needed.
- Brake Lines: Check brake lines for cracks and leaks. Replace with stainless steel braided lines for improved performance and durability.
- Master Cylinder: A faulty master cylinder can cause brake failure.
- Wheels and Tires:
- Wheels: Inspect wheels for damage and ensure they are properly balanced.
- Tires: Choose tires that are appropriate for your driving conditions and needs. Maintain proper tire pressure for optimal performance and safety.
Potential Challenges and Solutions:
- Rusty Brake Lines: Removing rusty brake lines can be challenging. Use penetrating oil and specialized tools to avoid damaging the lines.
- Stuck Caliper Bolts: Caliper bolts can become seized over time. Use heat and penetrating oil to loosen them.
IV. Body and Interior Parts
While less critical to immediate performance, maintaining the body and interior preserves the aesthetic appeal and comfort of your Cherokee.
- Body Panels: Fenders, doors, hoods, and quarter panels. Sourcing rust-free body panels can be challenging but is essential for a clean restoration.
- Glass: Windshield, windows, and rear glass. Replace cracked or broken glass for safety and visibility.
- Interior Components: Seats, carpets, dashboards, and trim. Consider replacing worn or damaged interior components to improve comfort and aesthetics.
- Lighting: Headlights, taillights, and marker lights. Ensure all lights are functioning properly for safety and visibility.
Tips:
- Salvage Yards: Salvage yards can be a great source for used body and interior parts at a fraction of the cost of new parts.
- Online Forums: Online forums dedicated to Jeep Cherokees can be valuable resources for finding parts and getting advice from other enthusiasts.
V. Electrical System Parts
The electrical system powers all of your Cherokee's vital functions, from the engine to the lights.
- Battery: Ensure the battery is in good condition and properly charged.
- Alternator: The alternator charges the battery and powers the electrical system.
- Starter: The starter cranks the engine to start the vehicle.
- Wiring Harness: Inspect the wiring harness for damage and corrosion.
- Fuses and Relays: Replace blown fuses and faulty relays promptly.
