• Rust: Rocker panels, lower door edges, and wheel arches are prone to rust, especially in regions with road salt.
• Exhaust System: Mufflers, catalytic converters, and pipes can rust through.

Performance Upgrades & Customization

Many WJ owners are enthusiasts who modify their vehicles for enhanced performance, off-road capability, or aesthetics:

• Lift Kits: For increased ground clearance and larger tires.

New OEM (Original Equipment Manufacturer) Parts

• Pros: Guaranteed fit, original quality, often come with a warranty.
• Cons: Highest price point, sometimes limited availability for older models.

Aftermarket Parts

• Source: Large online auto parts retailers (RockAuto, PartsGeek, Summit Racing, Quadratec, ExtremeTerrain), local auto parts stores (AutoZone, O’Reilly, Advance Auto Parts, NAPA).

• Reputable Aftermarket Brands: Moog (suspension), Bosch (electrical, sensors), Monroe/KYB (shocks/struts), Denso (spark plugs, sensors), Gates (belts/hoses), TYC/Depo (lighting), Spectra Premium (fuel tanks, radiators).

Used/Salvage Parts

• Pros: Most cost-effective, ideal for body panels or interior components that are hard to find new, original fit.

Online Retailers

These platforms offer convenience, competitive pricing, and vast selections:

• Amazon.com & eBay.com: Offer a mix of new aftermarket, OEM, and used parts from various sellers. Exercise caution and check seller ratings.

Key Considerations When Buying Parts

Making an informed decision when purchasing parts can save you time, money, and frustration.

• OEM vs. Aftermarket vs. Used:

  • OEM: Best for critical components where reliability and exact fit are paramount (e.g., engine internals, transmission components).
  • Aftermarket: Good for most common repairs, maintenance items, and performance upgrades. Research brand reputation.
  • Used: Ideal for non-critical body panels, interior trim, or hard-to-find components, but inspect thoroughly.

• Quality and Brand Reputation: Don’t always default to the cheapest option. A part that fails prematurely will cost you more in the long run due to repeat labor and parts. Read reviews, consult forums, and stick to known reputable brands.

• Compatibility (Trim Levels, Engine Types): The 1999 Grand Cherokee came with different engine options (4.0L I6, 4.7L V8), drive types (2WD, Quadra-Trac, Quadra-Drive), and trim levels (Laredo, Limited). Always verify part compatibility using your vehicle’s VIN (Vehicle Identification Number) or by matching the exact year, make, model, engine, and trim.

• Warranty: New parts (both OEM and reputable aftermarket) often come with a warranty, providing peace of mind. Used parts typically do not.

• Shipping & Returns: For online purchases, check shipping costs and the return policy before buying. Large or heavy items can incur significant shipping fees.

• Installation Difficulty: Consider whether you’ll be performing the installation yourself or hiring a professional. Some parts require specialized tools or expertise.

Tips for Successful Part Sourcing

• Know Your Vehicle’s Details: Have your VIN, engine type, and drive type readily available.
• Diagnose Accurately: Ensure you’ve correctly identified the problem before buying parts. A misdiagnosis leads to wasted money.
• Research Common Issues: Familiarize yourself with known WJ weaknesses to anticipate future needs.
• Compare Prices: Use multiple online retailers and local stores to find the best deal.
• Consider Kits: For major repairs (e.g., full suspension refresh, tune-up), consider buying a kit that bundles all necessary components, often at a discount.
• Join Online Communities: Jeep forums (e.g., JeepForum.com, NAXJA.org) and Facebook groups dedicated to the WJ Grand Cherokee are invaluable resources for advice, troubleshooting, and even finding used parts from other enthusiasts.

Practical Advice for 1999 Grand Cherokee Owners

Maintaining a 1999 Grand Cherokee is a rewarding endeavor. Prioritize safety-critical components like brakes, steering, and suspension. Don’t neglect preventive maintenance; a well-maintained WJ will last much longer and save you from more expensive repairs down the line. When faced with a major repair, weigh the cost of parts and labor against the vehicle’s overall condition and value. Many WJs, even with high mileage, are still worth repairing due to their robust design and lower depreciation compared to newer vehicles. Embrace the DIY spirit if you’re comfortable, as it can significantly reduce costs.

Frequently Asked Questions (FAQ)

Q: Are 1999 Grand Cherokee parts hard to find?
A: No, not generally. Due to the popularity and sheer number of WJs produced, parts are widely available from various sources (OEM, aftermarket, used). Some specific trim or rare components might require more searching, but common wear items and repair parts are abundant.

Q: Can I use parts from other WJ years (e.g., 2000-2004) on my 1999 model?
A: Many parts are interchangeable across the entire WJ generation (1999-2004), especially for mechanical and suspension components. However, there can be subtle differences, particularly with electrical components, interior trim, and some engine variants (e.g., early 4.7L vs. late 4.7L HO). Always cross-reference part numbers and confirm compatibility with your specific VIN.

Q: What’s the difference between OEM and aftermarket parts?

A: For many owners, absolutely. The 1999 WJ offers a robust platform, excellent capability, and a relatively simple design that makes repairs manageable. If the frame is solid and major components are in good shape, investing in repairs often makes more financial sense than buying a newer, more expensive vehicle.

Q: How do I know which part I need?
A: The best way is to consult your vehicle’s service manual, use online parts diagrams, or consult with a trusted mechanic. Having your VIN ready is crucial when ordering parts, as it allows retailers to verify exact fitment.

Q: What are the most common parts to replace on a 1999 Grand Cherokee?
