Ford Expedition Engine Mounts: A Guide for 2006-2018 Models
Feeling vibrations or hearing clunks? Your Expedition's engine mounts might be the cause.
- Vibrations at idle and clunking noises when shifting are the most common symptoms of failed engine mounts.
- Replacement is expensive primarily due to the high labor cost; the job is difficult due to tight access.
- Aftermarket brands like Anchor, DEA, and Westar are budget-friendly but may not last as long or ride as smoothly as OEM parts.
- Before replacing mounts for a vibration issue, rule out common engine problems, especially on the 5.4L V8.
Symptoms of a Failing Engine Mount
When an engine mount wears out, the signs are usually easy to notice. The rubber cracks or collapses, and on some hydraulic mounts, the internal fluid can leak out. Here’s what to look and listen for:
- Vibrations: You'll feel a strong vibration through the steering wheel, floor, or seats. It's often worst when the truck is in gear and you're stopped at a light.
- Clunking Noises: Loud clunks, bangs, or thuds when you shift from Park to Drive or Reverse are a classic sign. You might also hear them when you accelerate or brake hard as the engine shifts in its bay.
- Engine Movement: If you have a helper, you can check for this. With the hood open and the parking brake set firmly, have them briefly put the truck in Drive and then Reverse while holding the brake. If the engine lurches or jumps significantly, a mount has failed. 🎬 Watch: See these common failure symptoms in action.
- Leaking Fluid: Some Expedition mounts are hydraulic, meaning they are filled with a special fluid to dampen vibrations. When they fail, they can leak a dark, oily liquid that looks like a small oil leak on your garage floor. 🎬 See how a leaking hydraulic mount looks under the vehicle.
Rule Out Other Issues First
Especially on the 2006-2014 models with the 5.4L 3V Triton V8, other problems can cause vibrations that feel like a bad mount. Issues with timing components, like phasers or tensioners, are common and can create a rough idle. It's wise to make sure your engine is running smoothly before blaming the mounts.
Choosing the Right Aftermarket Mount
When replacing engine mounts, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. For a critical part like this, OEM mounts are generally considered the best for a perfect fit and the longest life. However, they are also the most expensive.
The aftermarket brands available—Anchor, DEA, and Westar—are economy-tier options. They meet the basic requirement of fitting the vehicle and will solve the immediate problem of a broken mount. However, based on mechanic and owner experiences, they may use harder rubber compounds that don't absorb vibration as well as OEM, and they generally don't last as long. Pioneer is another economy brand, sometimes seen as a slight step up if available.
- Tier 1 (Best Quality): OEM (Ford/Motorcraft) - Best vibration control and longest life.
- Tier 2 (Economy): Anchor, DEA, Westar, Pioneer - A budget-friendly fix that will get you back on the road, but may not feel as smooth or last as many miles as the original.
| Item | Estimated Cost |
|---|---|
| New OEM Engine Mounts (Pair) | $200 - $350 |
| New Aftermarket Engine Mounts (Pair) | $65 - $110 |
| Shop Labor | $550 - $850 |
| Total Aftermarket Replacement (Installed) | $615 - $960 |
| Total OEM Replacement (Installed) | $750 - $1,200 |
Note: Labor is the biggest part of the cost. The job is time-consuming due to tight access, especially on the driver's side.
Frequently Asked Questions
How many engine mounts does a Ford Expedition have?
A Ford Expedition has two main engine mounts (left and right) and one transmission mount. The transmission mount supports the rear of the transmission and also absorbs vibration. If your engine mounts are bad, it's very likely the transmission mount is also worn and should be inspected or replaced at the same time.
Should I replace both engine mounts at the same time?
Yes. It is highly recommended to replace engine mounts in pairs. If one has failed due to age and mileage, the other is not far behind. Replacing only one will put extra stress on the new part and the old one, and you may still have vibration issues.
Is the replacement something I can do myself (DIY)?
This is an advanced repair. It requires safely supporting the engine from above or below with special equipment, like an engine support bar or a floor jack with a wood block. Access to the bolts is very tight, and the job can be frustrating without the right tools and experience. For most owners, this job is best left to a professional mechanic.
🎬 Watch: A DIY walkthrough for replacing mounts in tight spaces.I found no recalls for this part. Is that right?
Correct. As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Ford or the NHTSA for engine mount failure on the 2006-2018 Ford Expedition. Failure of this part is typically considered normal wear and tear.
