Subaru Legacy Engine Mounts: A Guide for 2011-2024 Models
Experiencing vibrations or clunking noises in your Legacy? Your engine mounts might be the culprit.
- Symptoms include heavy vibration at idle and clunking noises when accelerating.
- OEM mounts provide the best ride quality but are expensive; budget aftermarket mounts may increase cabin vibration.
- The 2011-2014 Legacy uses a front mount and two bellhousing mounts, not a top 'pitch stop' mount.
- While DIY replacement is possible, it requires safely lifting the engine.
Is Your Subaru Legacy Shaking or Making Noise?
A worn-out engine mount can make your normally smooth Subaru feel rough. Because the mounts are designed to hold the heavy engine and absorb its vibrations, you'll notice when they start to fail. The most common signs are an increase in vibration felt in the steering wheel and throughout the car, especially when idling or starting the engine. You might also hear clunking, thumping, or banging sounds when you accelerate, decelerate, or shift gears from drive to reverse. In some cases, you may even see the engine move or lift excessively if you have someone rev it while you watch under the hood.

While you can drive with a failing mount, it's not recommended for long. A completely failed mount puts extra stress on the other mounts, the transmission, and drivetrain components like your axles. This can lead to more expensive repairs down the road.
Choosing a New Aftermarket Engine Mount
When replacing engine mounts on your 2011-2024 Legacy, you have a choice between Original Equipment Manufacturer (OEM) and aftermarket parts. For this specific part, the quality difference can be significant.
- OEM Mounts: These are the same parts your Subaru came with from the factory. They are often fluid-filled (hydraulic) to provide the best vibration damping. The consensus among Subaru owners and mechanics is that OEM mounts offer the best performance and longevity, but they are also the most expensive option, sometimes costing over $200 per mount.
- Aftermarket Mounts: Aftermarket brands offer a much more affordable alternative. However, many budget-friendly options from brands like Anchor, DEA, and Westar are solid rubber and may not be hydraulic. This can result in noticeably more vibration in the cabin compared to the original parts. Forum discussions frequently mention that these economy brands may not last as long and can sometimes fail prematurely.
Pro Tip: For a daily driver, the ride quality provided by OEM mounts is generally considered worth the extra cost. If budget is the primary concern, an aftermarket mount will secure the engine, but be prepared for a potential increase in cabin vibration. 🎬 See this walkthrough for replacing Legacy front engine mounts. Some owners even opt for a good-condition used OEM mount over a new, cheap aftermarket one.

Frequently Asked Questions
How many engine mounts does a Subaru Legacy have?
The 2011-2014 Legacy models typically have a three-point mounting system: one mount at the front of the engine, and two mounts on either side of the transmission bellhousing, plus a transmission crossmember mount. Unlike some other Subarus, they do not use a top "pitch stop" mount that connects to the firewall. Later models follow a similar principle.
Can I replace just one engine mount?
Yes, you can replace just the one that has failed. However, if one mount has worn out due to age and mileage, the others are likely not far behind. It's often a good idea to inspect all mounts and consider replacing them as a set to save on future labor costs.
Is replacing an engine mount a DIY job?
For an experienced DIY mechanic, yes. The process involves safely supporting the engine with a floor jack and a block of wood, removing the old mount, and installing the new one. Access to some of the bolts can be tight, and it requires the right tools like long extensions and ratcheting wrenches. If you are not comfortable lifting and supporting your engine, it's best to leave this job to a professional.
