How Much Does It Cost To Replace a Motor Mount?
Motor mount replacement is one of those repairs that catches a lot of drivers off guard — it's not something most people think about until the symptoms become impossible to ignore. The cost varies widely depending on your vehicle, how many mounts need replacing, and where you have the work done.
What a Motor Mount Actually Does
A motor mount (also called an engine mount) connects the engine to the vehicle's frame or subframe. Most vehicles have two to four mounts, and their job is twofold: they hold the engine in place, and they absorb the vibration the engine produces so it doesn't transfer directly into the cabin.
Mounts are typically made with a combination of metal brackets and rubber inserts. The rubber is what does the dampening work — and it's what eventually breaks down. Some vehicles use hydraulic mounts, which are fluid-filled for even better vibration control. These are more expensive to replace than standard rubber mounts.
When a mount fails, the engine can shift under load, causing noticeable clunking, vibration, or a rough feel during acceleration, braking, or gear changes. In severe cases, a broken mount can allow the engine to move enough to damage surrounding components.
What Motor Mount Replacement Typically Costs
Across most vehicles and repair shops in the U.S., motor mount replacement generally runs between $200 and $600 per mount, including parts and labor. That range shifts considerably based on several factors.
| Factor | Lower End | Higher End |
|---|---|---|
| Mount type | Standard rubber | Hydraulic or active mount |
| Vehicle type | Common domestic sedan | Luxury, import, or performance |
| Mount location | Easy access, top of engine | Buried under other components |
| Labor rate | Independent shop | Dealership service center |
| Number of mounts | One failing mount | Multiple worn at once |
On simpler vehicles — a standard four-cylinder commuter car, for example — a single mount might cost $150–$300 in parts and labor at an independent shop. On a European luxury vehicle or a truck with a large engine, the same job can run $500–$900 or more per mount, especially if access requires removing other components first.
Why Labor Cost Is Often the Bigger Factor 🔧
Parts for a basic rubber mount can cost as little as $30–$80. The labor is often where the bill climbs. Some mounts are straightforward to swap out — accessible from the top, minimal disassembly required. Others sit in tight spots that require lifting and supporting the engine with a jack while the mount is removed, which adds significant time to the job.
Hydraulic mounts — common on many front-wheel-drive vehicles and some luxury cars — cost more in parts ($100–$300 each) and can take longer to install correctly.
Dealer labor rates typically run higher than independent shops, sometimes significantly so. A job quoted at $350 at an independent shop might be $550 or more at a dealership, using OEM parts.
DIY Motor Mount Replacement: Is It Worth It?
Technically, motor mount replacement is within reach for experienced home mechanics. The parts are widely available, and on some vehicles the job is relatively uncomplicated. But it does require:
- Safely lifting and supporting the vehicle
- Supporting the engine while the old mount is removed (typically with a floor jack and a block of wood under the oil pan)
- Torquing the new mount to specification
On vehicles where the mount is buried or where the engine needs to be raised significantly to access it, the job becomes considerably more complex. A mistake — particularly failing to properly support the engine — can cause serious damage.
The DIY savings can be real (sometimes $150–$300 in labor), but it depends entirely on your mechanical experience and which mount on which vehicle you're dealing with.
Variables That Shape Your Specific Cost
No two motor mount jobs cost exactly the same. The biggest factors at play:
- Number of mounts failing. If one rubber mount has cracked, others on the same vehicle have likely experienced similar wear. Some shops recommend replacing mounts in pairs or sets when mileage and condition warrant it.
- Vehicle age and access. Older vehicles sometimes have corroded or seized hardware that adds labor time.
- Transmission mounts. These are related but separate components. If you're hearing similar symptoms but the engine mounts check out fine, the transmission mount may be the culprit — or both may need attention at the same time.
- OEM vs. aftermarket parts. Aftermarket mounts are typically less expensive. Some are comparable in quality; others may not last as long or dampen vibration as effectively as the factory part.
- Regional labor rates. Shop rates in major metro areas can run $130–$180 per hour. In smaller markets, $80–$110 per hour is more common.
What the Range Looks Like in Practice
A straightforward single-mount replacement on a mainstream sedan at an independent shop: $200–$400.
Multiple mounts on a larger SUV or truck, at a dealership, using OEM parts: $800–$1,500+.
A hydraulic mount on a European import, at a specialist shop: $500–$900 for that mount alone.
These aren't quotes — they're the general shape of what drivers encounter. Your vehicle's year, make, model, which mount is failing, your local labor market, and the shop you choose all determine where your actual number falls. 🚗
