If you notice unusual vibrations while driving or clunking noises from the engine bay, it could be a sign that your engine mounts are wearing out.
Wondering what it’ll cost to fix the issue?
Well, you might have to shell out around $110 to $650 for a new engine mount.
If you don’t, it may put extra strain on surrounding components and lead to more costly bills, something no driver wants to deal with.
Let’s take a closer look at the average engine mount replacement cost, the common symptoms of a failing mount, and why it’s best to have an experienced mechanic handle the repair.

How Much Does an Engine Mount Replacement Cost?
Let’s find out the average cost of an engine mount or motor mount repair service:
A. Range
Although it’s difficult to pin down an accurate estimate, expect to spend roughly $110 to $650 for a new engine mount.
This includes:
- Replacement parts: $10 to $200
- Labor: $100 to $450
B. Factors Affecting Cost
The motor mount replacement cost varies by vehicle model and the labor costs in your area.
Other factors influencing the price include:
- Engine configuration: In tightly packed engine compartments, technicians may need to remove components, such as the air box or battery tray, to reach motor mounts near the firewall. This can increase the labor cost and time.
- Number of mounts: Cars with transverse engines, which are common in front-wheel-drive vehicles, typically use three to four mounts. Meanwhile, rear-wheel-drive vehicles with longitudinal engines have two motor mounts and a transmission mount. Vehicles with multiple engine mounts may cost more to repair if several of them need replacement.
Larger engines such as V6, V8, or diesel engines put greater stress on mounts, which can lead to faster wear and higher replacement costs over time.
- Type of engine mount: Basic rubber mounts are generally the most affordable. On the other hand, electronically controlled or hydraulic mounts used in modern vehicles are more expensive due to their complex design.
- Parts quality: Original equipment manufacturer parts (OEM mounts) are often more expensive but ensure a precise fit. Meanwhile, aftermarket replacement parts may be more affordable but vary in quality.
- Additional repairs: In some cases, related issues, such as oil leaks, a faulty transmission mount, or worn suspension components, may need to be addressed for the new engine mounts to function properly.
Addressing these problems can also increase the overall repair cost. For instance, replacing suspension system parts, such as a control arm, can cost you an additional $360 to $750.
That’s why you should contact a professional at the first sign of engine mount issues.
5 Surefire Signs You Need an Engine Mount Replacement
Some common symptoms of a failing engine mount include:
- Excessive noise: Worn motor mounts can cause knocking or clunking noises from the engine bay. When mounts fail, the engine can experience excessive movement and knock against nearby components. These sounds are often most noticeable during engine start or shutdown.
- Increased vibrations: Engine mounts hold the engine in place and reduce vibration. When they wear out due to weakened rubber, bonding failure, or fluid leaks, their ability to absorb vibration decreases. This can cause noticeable engine vibrations and cabin noise.
- Rough ride: A worn engine mount can cause a noticeable jolt or thump when shifting gears, as the engine and transmission may move excessively. This can become more noticeable at higher speeds as the engine works harder, making the ride feel less smooth than usual.
- Engine misalignment: Engine mounts keep the engine securely aligned within the engine bay. When they become worn or damaged, the engine may shift, tilt, or sag out of position. If you notice this, have the vehicle inspected by a qualified mechanic.
- Visible wear: Corrosion, cracks, warping, or flaking of the rubber mount indicates excessive wear. Such damage reduces its ability to absorb vibrations and maintain engine stability. If these signs appear, the mounts should be inspected and replaced promptly.
Now, let’s move on to the real question:
Can You Drive with a Bad Engine Mount?
No, it’s not advisable to drive with a failing engine mount. Engine mounts stabilize the engine, and when one fails, the engine can move more than intended.
Over time, this extra engine movement can strain connected components and reduce overall driving comfort. That’s why you should inspect and get a motor mount replacement done early to prevent further complications.
Engine mounts carry the weight of the engine every mile you drive. But even the strongest support has its limits.
How Long Do Engine Mounts Last?
Engine mounts typically last about 5 to 7 years. However, aggressive driving, high-torque engines, poor road conditions, and fluid leaks can shorten its lifespan. For this reason, it’s a good idea to have them inspected during routine maintenance or whenever other work is being done on the vehicle.
Regular inspections help maintain engine stability and smoother vehicle operation.
Now, before you roll up your sleeves to fix engine mount issues, it’s essential to understand the process.
How to Replace an Engine Mount: A General Know-How
To swap out an engine mount, you should properly support the engine and remove mounting components, which can be difficult without the right tools and experience.
Hiring a professional helps ensure the job is done safely and prevents potential damage to the engine or surrounding parts.
Here’s what they’ll do:
- Park the vehicle on a level surface, engage the parking brake, and disconnect the battery. They’ll then raise the vehicle with a jack if necessary and secure it with jack stands.
- Place a floor jack with a wooden block under the engine or oil pan to support its weight. This prevents the engine from shifting when the mechanic removes the mount.
- Locate the faulty engine mount and remove any components, such as the battery tray, engine covers, or brackets, that block access to it. They’ll loosen and remove the mounting bolts connecting the mount to the engine and chassis.
- Position the new engine mount in place and secure it with the mounting bolts. The mechanic will tighten the bolts to the manufacturer’s recommended torque specifications.
- Lower the engine back into position, remove the jack, and reinstall any removed components. They’ll start the vehicle and check for unusual vibrations or movement.
