Motor mount replacement typically costs between $300 and $1,200 per mount, depending on which mount has failed, your vehicle's make and model, and whether you go to a dealership or independent shop

A motor mount is a rubber-and-metal assembly that holds your engine in place and absorbs vibration as it runs. When one fails, you'll feel severe shaking through the steering wheel, floor, or gear shift—especially when you accelerate or shift into gear. The cost to replace it includes both the part itself and the labor to remove and install it, which can be anywhere from one to four hours depending on the mount's location.

The wide range in price reflects real differences in how hard each mount is to reach. A front mount on some vehicles takes 45 minutes; a rear mount on others requires removing the transmission. Your vehicle's age and complexity matter too. A 2005 Honda Civic will cost less to repair than a 2020 luxury sedan with the same problem.

Key Takeaways

  • Motor mount replacement costs $300 to $1,200 per mount, with labor typically running $150 to $400 and the part itself $100 to $800 depending on location and vehicle type.
  • Dealerships charge 20 to 40 percent more than independent shops for the same work, but may have faster access to OEM parts and warranty coverage.
  • Severe engine vibration, clunking sounds when shifting, or visible cracks in the rubber are signs a mount has failed and needs replacement soon.
  • Delaying replacement can damage the transmission, radiator hoses, or engine bay components as the engine shifts excessively under load.

What a motor mount actually does and why it fails

Your engine produces constant vibration as pistons fire and move up and down thousands of times per minute. Without motor mounts, that vibration would transfer directly to the frame and cabin, making the car unbearable to drive. The mounts are designed to flex and absorb that energy.

Each mount is made of rubber bonded to metal brackets. The rubber degrades over time from heat, oil exposure, and constant flexing—typically after 5 to 10 years or 80,000 to 150,000 miles. Once the rubber cracks or separates from the metal, the mount can no longer hold the engine steady. The engine shifts excessively during acceleration and gear changes, and you feel it as violent shaking.

Most vehicles have three to four motor mounts: front, rear, and one or two on the sides. Usually only one fails at a time, though if your car is older or has very high mileage, multiple mounts may be near the end of their life. A mechanic can inspect all of them while replacing the bad one and tell you which others are at risk.

Dealership versus independent shop pricing

A dealership will charge you more for the same job—typically 20 to 40 percent more than an independent shop. A dealership might quote $800 to $1,200 for a single mount replacement; an independent shop might quote $500 to $900 for identical work on the same vehicle.

The difference comes down to overhead and parts sourcing. Dealerships have higher rent, more administrative staff, and use OEM (original equipment manufacturer) parts, which cost more than aftermarket equivalents. Independent shops often use quality aftermarket parts and have lower overhead, so they pass savings to you.

The trade-off is warranty and convenience. Dealerships typically warranty their work for 12 months or 12,000 miles; independent shops vary widely, so ask before you commit. Dealerships also have factory service bulletins and specialized diagnostic equipment for your specific vehicle, which can matter if the problem is unusual. For a straightforward motor mount replacement on a common vehicle, an independent shop is usually the better value.

Labor time and part cost breakdown

The total bill splits into two parts: the mount itself and the time to install it. On most vehicles, the part costs $100 to $400 if it's an aftermarket mount, or $200 to $800 if it's OEM. Labor typically runs $150 to $400 depending on how long the job takes.

A front motor mount on a sedan might take 1 to 1.5 hours of labor. A rear mount on an SUV or truck can take 3 to 4 hours because the mechanic may need to remove the transmission crossmember, transmission, or other components to access it. Some vehicles require engine removal entirely, which pushes labor into the $600 to $1,000 range on its own.

Ask your mechanic for a labor estimate before they start work. Most shops charge a flat rate based on the vehicle's year, make, and model—they look it up in a labor guide and quote you that time multiplied by their hourly rate. Hourly rates at independent shops typically range from $75 to $150; dealerships charge $120 to $200 per hour. If the job takes longer than estimated, ask whether you'll be charged extra or if the shop will absorb the overage.

Signs a motor mount has failed

The most obvious sign is severe engine vibration felt through the steering wheel, pedals, or floor, especially when you accelerate hard or shift from Park to Drive. You might also hear a loud clunk or thud when you shift gears, as the engine lurches forward or backward without the mount to control it.

Look under the hood for visible cracks in the rubber or separation between the rubber and metal bracket. If you can see daylight between the rubber and the metal, the mount is shot. Some mounts also leak fluid—the rubber can degrade to the point where it no longer seals, and engine oil or coolant seeps out.

Don't ignore these signs. A failed mount lets the engine move excessively, which can damage radiator hoses, transmission lines, or the fan shroud. In extreme cases, the engine can contact the frame or firewall, causing much costlier damage. Replacing a mount now costs $300 to $1,200; repairing engine bay damage from a neglected mount can cost thousands.

When to replace all mounts at once versus one at a time

If only one mount has failed and the others look intact, you can replace just that one. However, if your vehicle is over 100,000 miles and you're already paying for labor to access the engine bay, it's often worth replacing all mounts at the same time. The additional parts cost $300 to $1,500, but you avoid paying labor twice in the next few years.

Ask your mechanic to inspect all mounts while they have the engine area open. If two or more show cracks or separation, replacing them together makes financial sense. If only one is bad and the others are solid, do one now and monitor the others. Some shops will note the condition of the other mounts in writing so you have a record if they fail later.

This decision also depends on your vehicle's age and your plans. If you own a 15-year-old car you plan to keep for another five years, replacing all mounts now might be the last time you deal with this problem. If you're selling the car in a year, replacing just the failed mount is the economical choice.

How to reduce the cost

Get quotes from at least two independent shops before committing. Call ahead and describe the symptom—severe vibration when accelerating—so they can give you a ballpark estimate over the phone. Most shops will quote within a range, and you can compare apples to apples.

Ask whether the shop uses OEM or aftermarket parts and whether you have a choice. Aftermarket mounts are usually $100 to $200 cheaper than OEM and are often made by the same manufacturers that supply dealerships. Quality varies, so ask the shop which brand they use and whether they stand behind it.

If you're handy, you might be able to replace a motor mount yourself on some vehicles, though it's not a beginner job. You'll need a jack, jack stands, and sometimes special tools to support the engine safely while you remove the mount. The risk of dropping the engine or injuring yourself is real. Unless you have experience with engine work, the labor cost is worth paying to avoid that risk.

Frequently Asked Questions

Can I drive with a bad motor mount?

You can drive short distances, but the severe vibration will worsen over time and can damage other engine bay components. The longer you wait, the higher the risk of transmission damage or engine contact with the frame. Have it replaced within a week or two of noticing the symptoms.

Will a motor mount replacement affect my warranty?

No. Motor mount replacement is routine maintenance and won't void your vehicle's warranty. If the mount failed due to a defect in the bracket or engine itself, the manufacturer might cover the replacement, but that's rare. Ask the dealership if they'll cover it under warranty before you pay.

How long does a motor mount replacement take?

Most jobs take 1 to 4 hours depending on which mount has failed and your vehicle's design. A front mount on a sedan might be done in an hour; a rear mount on a truck could take most of a day. Ask the shop for a time estimate when you get the quote.

Is it worth replacing the mount at a dealership instead of an independent shop?

Only if you want OEM parts and a longer warranty, or if the independent shops in your area have poor reviews. For a straightforward motor mount replacement, an independent shop with good ratings will save you $200 to $400 and do the same quality work.

What happens if I ignore a bad motor mount?

The engine will shift more and more under load, potentially damaging radiator hoses, transmission cooler lines, or the fan shroud. In rare cases, the engine can contact the frame or firewall, which is expensive to repair. Replacing the mount now costs $300 to $1,200; ignoring it could lead to repairs costing thousands.
