However, owning a 25+ year-old vehicle means dealing with maintenance and repairs. That's where understanding the world of 1999 Jeep Cherokee parts becomes crucial. This guide will delve into the various aspects of sourcing, selecting, and utilizing parts for your '99 XJ, ensuring it continues to conquer trails and highways for years to come.
Why Understanding 1999 Jeep Cherokee Parts is Essential
Reviving the Legend: A Comprehensive Guide to 1999 Jeep Cherokee Parts
Owning a classic like the '99 Cherokee is rewarding, but it also demands a commitment to upkeep. Understanding the parts specific to this model year, where to find them, and how to choose the right ones can save you time, money, and frustration. Whether you're tackling a minor repair or embarking on a full restoration, knowledge of 1999 Jeep Cherokee parts is your key to keeping this legendary vehicle alive and well.
1. Engine Components: Keeping the Heart Pumping
The 1999 Cherokee predominantly featured two engine options:
- 4.0L Inline-Six: This legendary engine is known for its durability and torque. Parts like pistons, connecting rods, crankshafts, cylinder heads, and complete engine rebuild kits are readily available.
- 2.5L Inline-Four: While less common, this engine offered decent fuel economy. Parts for this engine are still obtainable, though may require more searching.
Considerations when sourcing engine parts:
- OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) parts are manufactured by or for Jeep and guarantee fit and performance. Aftermarket parts can be more affordable, but quality can vary significantly. Research brands carefully.
- Remanufactured Parts: These parts have been rebuilt to meet OEM specifications and can be a cost-effective alternative to new parts.
- Engine Codes: Always verify the engine code (usually found on the engine block or in the vehicle's VIN) to ensure compatibility with specific parts.
Practical Advice: Before replacing any engine part, diagnose the issue thoroughly. Use a scan tool to read diagnostic trouble codes (DTCs) and consult a repair manual or online resources for troubleshooting guidance.
2. Transmission and Drivetrain: Power to the Wheels
The 1999 Cherokee typically came with either an automatic or manual transmission. Key parts in this system include:
- Transmission Components: Clutch kits (manual), torque converters (automatic), filters, fluid, seals, and rebuild kits.
- Transfer Case: Responsible for transferring power to either two or four wheels. Parts include chains, gears, seals, and shift linkages.
- Driveshafts: Transfer power from the transfer case to the axles. Parts include U-joints, slip yokes, and driveshaft assemblies.
- Axles: The final link in the drivetrain, responsible for turning the wheels. Parts include axle shafts, bearings, seals, differentials, and gears.
Important Considerations:
- Transmission Type: Clearly identify whether you have an automatic or manual transmission before ordering parts.
- Gear Ratio: The axle gear ratio affects performance and fuel economy. Replacing gears requires specialized knowledge and tools.
- 4x4 System: If your Cherokee is a 4x4 model, ensure that the transfer case and axle parts are compatible with your specific system (e.g., Command-Trac or Selec-Trac).
How-To Tip: Regularly inspect your driveshafts for wear and tear, especially the U-joints. A failing U-joint can cause vibrations and eventually lead to a complete driveshaft failure.
3. Suspension and Steering: Handling the Terrain
The Cherokee's suspension and steering systems are crucial for both on-road comfort and off-road capability. Common parts include:
- Shocks and Struts: Control body roll and improve ride quality.
- Leaf Springs (Rear): Provide support and absorb bumps.
- Coil Springs (Front): Provide support and absorb bumps.
- Control Arms: Connect the suspension to the frame.
- Ball Joints: Allow for steering articulation.
- Tie Rods: Connect the steering box to the steering knuckles.
- Steering Box/Gear: Amplifies steering input.
Benefits of Upgrading:
- Lift Kits: Increase ground clearance for off-road use.
- Heavy-Duty Shocks: Improve handling and ride quality, especially with larger tires.
- Reinforced Control Arms: Enhance durability and prevent bending or breaking during off-road adventures.
Potential Challenges:
- Alignment: After replacing suspension or steering components, a wheel alignment is essential to prevent uneven tire wear and handling issues.
- Rusty Bolts: Expect to encounter rusted bolts, especially on older Cherokees. Penetrating oil and patience are your best allies.
4. Brakes: Stopping Power
A reliable braking system is paramount for safety. Common brake parts include:
- Brake Pads: Provide friction to slow the vehicle.
- Brake Rotors/Drums: The surfaces that the brake pads press against.
- Brake Calipers/Wheel Cylinders: Apply pressure to the brake pads.
- Brake Lines: Carry brake fluid to the calipers/wheel cylinders.
- Master Cylinder: Supplies brake fluid pressure to the system.
Important Considerations:
- Brake Pad Material: Choose brake pads based on your driving style. Ceramic pads offer low noise and dust, while semi-metallic pads provide better stopping power.
- Rotor/Drum Condition: Inspect rotors and drums for cracks, warping, or excessive wear. Resurface or replace them as needed.
- Brake Fluid: Replace brake fluid regularly to prevent corrosion and maintain optimal braking performance.
How-To Guide (Replacing Brake Pads):
- Loosen the lug nuts on the wheel.
- Jack up the vehicle and secure it with jack stands.
- Remove the wheel.
- Remove the brake caliper bolts.
- Remove the old brake pads.
- Compress the caliper piston.
- Install the new brake pads.
- Reinstall the caliper and bolts.
- Reinstall the wheel and lug nuts.
- Lower the vehicle and torque the lug nuts to the proper specification.
- Pump the brake pedal several times to seat the pads.
5. Body and Interior: Restoring the Classic Look
While mechanical components are essential, restoring the body and interior can significantly enhance the value and enjoyment of your '99 Cherokee. Key parts include:
- Body Panels: Fenders, doors, hoods, quarter panels, and floor pans.
- Bumpers: Front and rear bumpers.
- Grille: The iconic Cherokee grille.
- Headlights and Taillights: Improve visibility and safety.
- Interior Trim: Seats, carpets, door panels, dashboards, and headliners.

Tips for Sourcing Body and Interior Parts:
- Salvage Yards: Offer a wide selection of used parts at affordable prices.
- Online Marketplaces: Sites like eBay and Craigslist can be valuable resources.
- Specialty Jeep Parts Retailers: Offer new and reproduction parts specifically for Cherokees.
6. Electrical System: Keeping the Lights On
The electrical system powers everything from the engine to the lights and accessories. Key parts include:
- Battery: Provides power to start the engine.
- Alternator: Charges the battery and powers the electrical system while the engine is running.
- Starter: Cranks the engine to start it.
- Wiring Harness: Connects all the electrical components.
- Sensors: Monitor various engine and vehicle parameters.
- Fuses and Relays: Protect the electrical system from overloads.
Potential Challenges:
- Wiring Issues: Older Cherokees can suffer from corroded or damaged wiring.
- Sensor Failures: Faulty sensors can cause a variety of engine and transmission problems.
- Grounding Issues: Poor grounding can lead to electrical problems.
7. Finding the Right Parts: Where to Look
Several avenues exist for sourcing 1999 Jeep Cherokee parts:
