Motor mount replacement cost averages $643 to $798 according to RepairPal's national engine mount estimate, with labor at $328 to $481 and parts around $316. AutoZone puts labor at roughly $100 to $450 per mount depending on access. Insert-style polyurethane kits can cut the cost further because the mount shell stays in place. 

Repairs to motor mounts and engine mounts can look expensive on a quote, and the price can swing a long way between vehicles. That is because the cost of the mount itself is often small compared with the labor needed to support the engine and reach the mount. Here is how motor mount replacement cost breaks down, why it varies, and how to get the best value from our engine mount bushings. 

How Much Does It Cost to Replace Motor Mounts? 

RepairPal's national estimate, last updated September 3, 2026, puts the average engine mount replacement cost at $643 to $798 before taxes and fees. Labor makes up $328 to $481 of that total and parts about $316 to $317. AutoZone's guide notes that labor alone typically runs about $100 to $450 per mount, depending on how hard the mount is to reach.

Treat these figures as a planning guide for what motor mounts cost rather than a quote. Your engine, mount type, labor rate and the number of mounts being replaced all change the final number. 

Why Engine Mount Repair Cost Varies So Much 

The biggest factor in motor mount repair cost is access to the mount. AutoZone notes that a mount sitting on top of the engine may take about 30 minutes to swap, while one buried deep in the engine bay can take two hours or more. Some vehicles need subframe sections or other components removed before the mount can come out. 

Several other factors also move the final price up or down: 

  • Mount type: Hydraulic and active mounts cost more than simple rubber designs.
  • Number of mounts: Replacing a full set costs more than a single mount but saves repeat labor later.
  • Engine support: The engine must be safely supported with proper equipment while each mount is out.
  • Seized hardware: Corroded bolts on older vehicles add time to every mount. 

Ask your shop to list which mounts are being replaced and why. A quote for "motor mounts" should name each position, its part number and the reason it failed.

How Much Are Motor Mounts if You Use Insert Kits? 

Insert kits are one of the most cost-effective engine mount repairs available. Instead of replacing the complete mount, a polyurethane insert fills or replaces the worn cushion inside the existing mount shell, so the metal brackets stay on the vehicle. On applicable platforms our insert kits install in under an hour, often without removing the full mount. 

That keeps both parts and labor down, and the polyurethane insert controls engine movement better than the rubber it replaces. For vehicles where the mount shell is cracked or the brackets are damaged, our complete mount sets take up to about two hours to fit. Read more in our guide to motor mount inserts.

Should You Replace One Motor Mount or All of Them? 

Replace a single mount when diagnosis shows only one has failed and the others are in good condition. If the vehicle has high mileage and the mounts are all the same age, replacing the full set at once often makes more sense. The remaining old mounts carry more load once one fails, so they are rarely far behind. 

Whatever you choose, make sure the original complaint is rechecked afterward. Engine vibration can also come from misfires or other problems, so confirm the diagnosis first with our guide to bad motor mount symptoms.

Ways to Save on Motor Mount Replacement 

  • Choose inserts where they fit: Keep the existing shell and pay for less labor.
  • Get the diagnosis right: Confirm which mount has failed before paying for a full set.
  • Buy parts that last: Polyurethane outlasts rubber, so you avoid paying for the same labor twice.
  • Do it yourself safely: Many owners can fit insert kits at home with an engine support and basic tools. 

Our engine mount products carry warranties from 3 years up to limited lifetime, depending on the product, and installation guides are available for most of the range. 

FAQs

Looking for more information about motor mount replacement cost? Below we answer the most commonly asked questions

How much does it cost to replace motor mounts?

How much to replace motor mounts depends on the vehicle, but RepairPal's national estimate averages $643 to $798, including $328 to $481 in labor. Costs vary with access, mount type and how many mounts you replace.

How much is a motor mount?

AutoZone puts simple rubber or steel mounts at about $10 to $150 for the part. Hydraulic and active mounts cost more, starting from about $50 and rising to $200 and up.

Why is engine mount replacement cost so high?

Labor is the main reason, because the engine must be supported and some mounts are hard to reach. A mount buried in the engine bay can take two hours or more.

Is it worth replacing motor mounts on an older car?

Usually, yes, if the car is otherwise in good condition. Worn mounts can damage hoses, wiring and exhaust parts, and replacing them restores a smooth, quiet drive.

Are motor mount inserts cheaper than new mounts?

Inserts are often cheaper because the existing mount shell stays on the vehicle. On applicable platforms our insert kits install in under an hour.

Can I replace motor mounts myself?

Many owners can, provided the engine is supported with proper equipment and never with a jack alone. If you are unsure about supporting the engine safely, have a professional do the job.
