Whether you're tackling rough terrain, towing heavy loads, or simply seeking a more refined ride, these mounts eliminate the flex and slop found in worn-out OEM parts, resulting in better handling, reduced engine movement, and extended longevity for your drivetrain components. Backed by rigorous testing and designed for easy installation, this **3-piece set** ensures a seamless upgrade that enhances both performance and reliability for your Expedition.
### Pros and Cons of buying a A5863/A5669/A5657 Front Engine Mounts and Rear Trans Mount (3-Piece Set) for a 2014-2007 Ford Expedition 5.4L 4WD
#### **Pros:**1. **Compatibility and Fitment** These mounts are specifically designed for the 2002-2014 Ford Expedition with a 5.4L V8 engine and 4WD system. They should fit without modification, reducing the risk of installation issues.
2. **Improved Ride Comfort** Worn or damaged engine mounts can cause excessive vibration, clunking noises, and an unstable ride. Replacing them with high-quality aftermarket parts can restore smooth operation and reduce road noise.
3. **Prevents Further Damage** A failing engine mount can lead to misalignment of the engine or transmission, potentially causing damage to related components like the exhaust, suspension, or drivetrain. Replacing them proactively avoids costly repairs.
4. **Durability and Performance** These mounts are often made from reinforced rubber and steel, designed to withstand the weight and stress of a large SUV like the Expedition. They may offer better longevity than OEM parts, especially if the vehicle sees heavy use.
5. **Easier Installation** Some aftermarket sets come with detailed instructions and may include tools or hardware needed for installation, simplifying the process compared to sourcing individual OEM parts.
6. **Cost-Effective Alternative to OEM** While not always cheaper, aftermarket sets can be more affordable than buying original equipment manufacturer (OEM) parts, which may require ordering through Ford or a dealership.
7. **Reduced Engine Movement** Properly functioning mounts keep the engine and transmission securely in place, minimizing stress on the drivetrain and improving overall vehicle handling.

#### **Cons:**1. **Quality Variability** Not all aftermarket parts are created equal. Some brands may use lower-grade materials or poor manufacturing processes, leading to premature failure or poor performance. Researching the brand s reputation is crucial.
2. **Potential for Incorrect Fitment** While these mounts are listed as compatible, slight variations in vehicle modifications (e.g., lifted suspension, aftermarket exhaust) could cause fitment issues. Double-checking with the manufacturer or a trusted mechanic is advisable.
3. **Installation Complexity** Replacing engine mounts requires lifting the vehicle, removing the engine or transmission mounts, and often draining fluids (e.g., power steering or coolant). This is a labor-intensive job that may require professional help, adding to the cost.
4. **Noise or Vibration Transfer** In some cases, aftermarket mounts may not dampen vibrations as effectively as OEM parts, leading to a slightly firmer ride or increased road noise. This depends on the specific brand and design.
5. **Limited Warranty or Return Policy** Some aftermarket suppliers offer minimal warranties or no return policy, which could be a risk if the parts fail shortly after installation. Checking warranty terms before purchasing is important.
6. **Compatibility with Modifications** If the Expedition has aftermarket modifications (e.g., heavy-duty suspension, performance exhaust, or engine upgrades), the stock mounts may not be sufficient. Custom or heavy-duty mounts may be needed instead.
7. **Potential for Over-tightening** Improperly torqued mounts can lead to premature wear or damage. Following the manufacturer s torque specifications is essential to avoid this issue.

### **Conclusion:**The A5863/A5669/A5657 front engine mounts and rear transmission mount set is a viable option for restoring proper function to a 2002-2014 Ford Expedition 5.4L 4WD. The benefits of improved ride comfort, reduced vibration, and prevention of further damage outweigh the risks for most owners, provided the parts are of high quality and installed correctly.
However, the cons such as potential quality issues, installation challenges, and the need for careful fitment checks highlight the importance of selecting a reputable brand and considering professional installation. If the vehicle has significant modifications or a history of rough treatment, investing in a higher-quality or heavy-duty set may be worth the extra cost.

### **Recommendation:**1. **Verify Compatibility** Confirm that these mounts are compatible with your specific Expedition model year and any modifications. Check with the manufacturer or a trusted mechanic if in doubt.
2. **Choose a Reputable Brand** Opt for well-reviewed brands known for durability and quality, such as **Eibach, Bilstein, or Fox**. Avoid no-name or extremely cheap options that may fail quickly.
3. **Budget for Professional Installation** Unless you have experience with engine/transmission work, consider having a mechanic install the mounts. Proper installation ensures safety and longevity.
4. **Inspect for Additional Wear** While replacing these mounts, inspect other related components (e.g., bushings, suspension parts, and drivetrain) for signs of wear. Addressing multiple issues at once can save time and money.
5. **Consider Heavy-Duty Options** If the Expedition is used for towing, off-roading, or heavy loads, upgrading to heavy-duty mounts (e.g., **Eibach Power Mounts**) may provide better support and durability.
6. **Check Warranty and Return Policy** Ensure the supplier offers a reasonable warranty (e.g., 1-2 years) and a clear return policy in case of defects.
**Final Verdict:** For most 2002-2014 Ford Expedition owners experiencing engine mount issues, this 3-piece set is a practical and cost-effective solution. Prioritize quality, proper installation, and compatibility to maximize benefits and minimize risks. If unsure, consult a Ford specialist or Expedition forum for additional insights.
