### **Pros and Cons of buying a Lincoln KL1Z3504A (2018-2023 Navigator) Power Steering Gear Rack Pinion (Part # KL14-3D070-AA)**

1. **OEM Quality and Fit** This is an original equipment manufacturer (OEM) part, meaning it is designed to match the exact specifications of the vehicle s original steering system. This ensures proper alignment, performance, and compatibility without modifications.

2. **Reliability and Durability** OEM parts are built to meet Ford/Lincoln s strict quality standards, reducing the risk of premature failure compared to aftermarket alternatives that may cut corners on materials or manufacturing.

3. **Warranty Coverage** Purchasing from an authorized dealer or a reputable supplier often includes a warranty (typically 12 60 months), providing peace of mind against defects or early wear.

4. **Compatibility with Original System** Since it is the exact replacement part, it integrates seamlessly with the vehicle s steering fluid lines, mounts, and sensors, avoiding potential leaks or misalignment issues that can arise with non-OEM parts.

5. **Resale Value Protection** Using OEM parts helps maintain the vehicle s integrity, which can be beneficial if you plan to sell or trade-in the car in the future. Dealers and buyers often prefer vehicles with original components.

6. **Performance Consistency** The part is engineered to deliver the same feel, responsiveness, and precision as the original, ensuring a smooth driving experience without compromises.

7. **Easier Installation** Because it is the exact replacement, mechanics familiar with the vehicle will have less trouble installing it, reducing labor time and potential errors.

1. **Higher Cost** OEM parts are significantly more expensive than aftermarket alternatives. The price can range from **$500 to $1,200 **, depending on the supplier and region, compared to aftermarket options that may cost **$200 $500**.

2. **Longer Lead Times** OEM parts, especially those ordered directly from Ford or authorized dealers, may take **1 4 weeks** to arrive, whereas aftermarket parts can often be shipped within **2 5 business days**.

3. **Limited Availability** If the part is discontinued or hard to source, finding an OEM replacement may require contacting multiple suppliers or waiting for inventory restocks.

4. **Potential Overkill for Some Buyers** If the steering rack is failing due to minor wear (e.g., fluid leaks, minor play) rather than a complete failure, an OEM replacement might be more expensive than necessary. In such cases, a refurbished or high-quality aftermarket part could suffice.

5. **Dealer Markup** Purchasing from a dealership often includes a higher markup compared to buying from an online retailer, parts store, or direct from Ford s wholesale division.

6. **Environmental Impact** OEM parts contribute to higher production costs and waste, as they are manufactured specifically for Ford/Lincoln vehicles, even if demand is lower than for mass-produced aftermarket alternatives.
