- Symptoms of bad mounts include heavy vibration at idle, clunking noises on acceleration, and visible engine movement.
- It is strongly recommended to replace engine mounts and the transmission mount as a complete set for a durable repair.
- Aftermarket brands like Anchor, DEA, and Westar are affordable standard replacements, but OEM may offer greater longevity.
- Ensure you buy the correct part for your specific year and drivetrain (2WD vs. 4WD), as fitments can differ.
Symptoms of a Failing Engine Mount
When an engine mount wears out, the signs are hard to ignore. 🎬 Watch this video to see common signs of mount failure. The rubber cracks and hardens from age and heat, or the internal hydraulic fluid can leak out, causing the mount to collapse. Watch for these common symptoms in your Navigator:
- Excessive Vibration: This is the most common sign. You'll feel a noticeable vibration in the steering wheel, floor, or seats, especially when the vehicle is idling in gear at a stoplight.
- Clunking or Thumping Noises: Loud clunks, bangs, or thumps from the engine bay are a serious red flag. These sounds are often heard when you accelerate, brake, or shift from Drive to Reverse as the engine moves excessively and hits other components.
- Engine Movement: A healthy engine should have very little movement. If you have an assistant put the vehicle in gear with the brake held firmly, and you see the engine lurch or lift more than an inch or two when the gas is lightly pressed, a mount has likely failed.
- Visible Damage: Sometimes, you can see the problem. Look for deep cracks, 🎬 Learn how to locate and inspect your engine mounts. separated rubber, or signs of fluid leakage from the mounts themselves.
Don't Ignore a Bad Mount
Continuing to drive with a broken engine mount can cause serious problems. The excessive engine movement can damage other components like cooling hoses, exhaust manifolds, and transmission linkages. In severe cases, it can become a significant safety risk.
Choosing the Right Aftermarket Engine Mount
When replacing your Navigator's engine mounts, you'll find several aftermarket options. While OEM (Original Equipment Manufacturer) mounts from Ford are available, aftermarket parts offer comparable quality for a lower price. The key is to choose a reputable brand. The brands available in our inventory (Anchor, DEA, Westar, Pioneer) are generally considered standard-grade replacements.
Here's an honest breakdown:
- Standard Replacement (Anchor, DEA, Westar): These brands are widely available and offer a cost-effective solution. They are designed to meet original specifications and will restore your vehicle's ride quality. However, online forums show mixed reviews regarding their long-term durability compared to OEM. Some users report success, while others have experienced premature failure. For a daily-driven vehicle, they are a practical choice that balances cost and function.
- Pioneer: This brand also falls into the standard replacement category. Some user feedback suggests that fit and finish can be inconsistent, sometimes requiring extra work during installation.
Pro Tip: Replace in Sets
Your Navigator has at least two engine mounts and one transmission mount. When one fails, the others have been subjected to the same age and stress. It's highly recommended to replace all mounts at the same time to ensure proper engine alignment and prevent the new mount from failing prematurely due to stress from old, worn mounts.

Frequently Asked Questions
How many engine mounts does my 1998-2007 Navigator have?
Your Navigator has a three-point mounting system: a left engine mount, a right engine mount, and a rear transmission mount that supports the back of the powertrain. All three work together to keep the engine and transmission secure.
Are the mounts different for 2WD and 4WD models?
Yes, in some cases, the part numbers for 2WD and 4WD models can be different, especially for the transmission mount. It is critical to use your vehicle's specific information (year, engine, and drivetrain) to ensure you order the correct-fitting parts.
Are there any recalls for Navigator engine mounts?
My search found no specific engine mount recalls for the 1998-2007 Lincoln Navigator. Recalls for loose engine mount fasteners were issued for much newer 2020-2021 models, but these do not apply to the first or second-generation Navigators.
Can I replace just one broken mount?
While you can replace just the one failed mount, it is not recommended. The remaining old mounts are likely worn and will put extra stress on the new part, leading to a shorter lifespan. Replacing them as a set is the best practice for a lasting repair.
