A Practical Guide to Engine Mounts for the 2006-2010 Subaru Legacy
Experiencing engine vibration or clunking noises? It might be time to inspect your engine mounts.
- Symptoms of failure include increased vibration at idle, clunking noises, and visible engine movement.
- The 2006-2010 Legacy has two main engine mounts and a transmission mount that should also be inspected.
- Aftermarket brands like Anchor, DEA, and Westar are budget-friendly but may offer less vibration damping than OEM parts.
- Ignoring a failed engine mount can lead to damage to other components like hoses, wires, and the exhaust system.
Signs of a Failing Engine Mount
When an engine mount fails on your Legacy, the symptoms are hard to ignore. The rubber that isolates the engine from the chassis degrades, allowing for excessive movement and vibration. You are the best judge of how your car normally feels and sounds, so pay attention to any new or worsening symptoms.
Common Failure Symptoms:
🎬 Watch this video to identify symptoms of a bad mount.- Increased Vibration: A noticeable increase in vibration felt in the steering wheel, floor, or seats, especially when idling in gear. This happens because the worn rubber can no longer absorb the engine's vibrations.
- Clunking or Knocking Noises: Loud clunks or thuds during acceleration, braking, or when shifting between drive and reverse. This sound is often the engine itself moving and hitting other components in the engine bay.
- Engine Movement: You might notice the engine lurch or jerk when you start the car or turn it off. In some cases, you can physically see the engine move an inch or two when revving it with the hood open.
- A Rougher Ride: If gear changes feel jolting or less smooth than before, it could be a sign that a failing mount is allowing the powertrain to shift excessively.
Choosing the Right Aftermarket Engine Mount
When replacing engine mounts on your Legacy, you have a choice between Original Equipment Manufacturer (OEM) parts and aftermarket options. For a daily driver, the goal is usually to restore the original ride quality.
- OEM Mounts: These are identical to the parts your Subaru was built with. They are typically made from a softer rubber compound designed to provide the best vibration absorption for a comfortable ride. The downside is a higher cost.
- Aftermarket Mounts: Brands like Anchor, DEA, and Westar offer direct-fit replacements at a more budget-friendly price. Forum discussions and user reviews on these brands are mixed; some users report they are perfectly adequate for daily driving, while others claim they fail prematurely or are made from harder rubber that increases cabin vibration compared to OEM. These brands are generally considered economy or standard-grade options. If you're looking for a cost-effective solution and can tolerate a potential slight increase in vibration, they are a viable choice.
Pro Tip: The 2006-2010 Legacy uses two main engine mounts, one on each side, which are often fluid-filled. There is also a transmission mount that helps stabilize the powertrain. It's often a good idea to inspect the transmission mount when you replace the engine mounts, as it experiences similar wear.
Cost of Replacing Engine Mounts
The cost to replace engine mounts can vary based on whether you do the work yourself or take it to a shop. The parts themselves are relatively affordable.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (per mount) | $57 - $96 |
| New OEM (per mount) | $130 - $250 |
| Shop Labor | $100 - $350 |
Note: Prices are estimates and can vary based on location and supplier. Labor costs depend on the shop's hourly rate.
Frequently Asked Questions (FAQ)
How many engine mounts does my 2006-2010 Legacy have?
This generation of Subaru Legacy typically has two main engine mounts (left and right) and one transmission mount. Some models may also have a pitch stop mount on top of the engine to control fore-aft movement, though this is less common on the 5th generation (2010+).
Can I install engine mounts myself? 🎬 Follow this step-by-step guide to replace your motor mounts.
Yes, this is a feasible DIY project for someone with mechanical experience. It requires safely supporting the engine with a jack and a block of wood or an engine hoist. You will need to unbolt the old mounts from the subframe and engine brackets, lift the engine slightly, and install the new ones. Access to some bolts can be tight.
Are the left and right engine mounts the same?
No, the left and right engine mounts are typically different parts with unique part numbers. It is crucial to order the correct mount for each side of the vehicle to ensure proper fitment.
What happens if I don't replace a bad engine mount?
Continuing to drive with a broken engine mount can cause further damage. The excessive engine movement can put stress on hoses, wiring, and exhaust components. In severe cases, it can damage the engine or transmission itself.
Are there any recalls for engine mounts on this Legacy?
As of early 2026, there are no specific recalls issued by the NHTSA for engine mounts on the 2006-2010 Subaru Legacy. Recalls for this vehicle range have been related to issues like airbag inflators, CVT cooling hoses, and control arms from a specific aftermarket supplier.
