Is it expensive to replace motor mounts?
Replacing motor mounts is typically a moderate repair. In most cases, you should budget roughly $400 to $1,200 per mount, including parts and labor, though prices can be lower for older cars and higher for luxury or performance vehicles.
Understanding motor mounts and why they fail
Motor mounts secure the engine to the vehicle frame and dampen vibration. Over time, mounts can crack, wear out, or leak hydraulic fluid, allowing more engine movement and increasing vibration and noise. Common culprits include high mileage, aggressive driving, heat exposure, and manufacturing variations. Replacing worn mounts restores smooth operation and helps protect components connected to the engine and drivetrain.
Types of motor mounts
Car makers use different mounts depending on the engine layout and design. The most common types you’ll encounter include:
- Hydraulic engine mounts: Rubber with a fluid-filled chamber to absorb vibrations.
- Solid or rigid mounts: Denser materials that transmit more vibration but offer firmer support, often found in performance applications.
- Semi-elliptical or dual mounts: Additional damping for V6 or V8 engines and complex alignments.
- Transmission mounts: Secure the transmission to the chassis and work in tandem with engine mounts.
Not all vehicles use the same arrangement; some cars have multiple engine mounts (up to four) and several related mounts (transmission, subframe, or torque rod mounts).
Cost to replace motor mounts
Prices depend on how many mounts are replaced, the type of mounts, and labor rates. The following ranges provide a practical guide.
- Parts: Expect $50 to $350 per mount for aftermarket parts; OEM or specialty mounts can cost more.
- Labor: Shop labor often ranges from $100 to $300 per mount, depending on complexity and regional rates.
- Total per mount: In many cars, a single mount replacement runs about $400 to $1,200 total (parts plus labor).
- Multi-mount jobs: Replacing two or more mounts at once is common; total job costs can range from $600 to $2,500 or more, depending on vehicle and location.
Premium brands and vehicles with challenging access—such as luxury or performance cars—tend to be at the upper end of these ranges, sometimes exceeding $2,000 for a full set on a high-end model.
Factors that influence price
The final price is shaped by several factors beyond the number of mounts. Consider the following:
- Number and location of mounts to replace (some cars have 2, 3, or 4 mounts across different locations).
- Mount type and material (hydraulic mounts cost more than rubber-only mounts; performance mounts may be pricier).
- Vehicle make, model, and engine layout (some engines require more labor or specialized tools).
- Labor rate in your area and whether the work is done at a dealership, independent shop, or by a mobile mechanic.
- OEM vs aftermarket parts; OEM parts tend to be more expensive but maintain factory characteristics and warranty.
- Additional tasks that may be required (transmission mount inspection, subframe bolts, exhaust clearance, or coolant lines).
Understanding these factors helps you form a realistic budget and compare quotes.
DIY vs professional replacement
Replacing motor mounts is doable for a capable DIYer with a full set of tools, a stable workspace, and a good manual. However, it can be labor-intensive, require engine support jacks, and may affect alignment sensors or belts. If you’re not confident, a professional shop can ensure the job is done safely and correctly, often with guarantees on parts and labor.
- DIY considerations: Access to a garage or driveway, proper safety equipment, and an appropriate tool set (jack stands, engine hoist or support, wrenches, torque specs).
- Professional advantages: Warranty on parts and labor, proper torque specs, and handling of any incidental issues discovered during replacement.
Before deciding, obtain multiple quotes and ask for itemized estimates that separate parts, labor, and any disposal or shop fees.
Symptoms that you may need motor mount replacement
Look for signs such as increased engine shake at idle, excessive engine movement when accelerating or braking, thick clunking or banging noises from the engine bay, or vibrations felt through the cabin, especially when the engine shifts under load.
Summary
Motor mounts are a critical buffer between the engine and the chassis. Replacement costs vary widely but typically fall in the mid to high hundreds per mount, influenced by mounting location, type, vehicle, and labor rates. If you notice vibration or unusual noises, have a mechanic inspect the mounts early to prevent further damage and avoid surprise costs. Getting several quotes can help you balance reliability, performance, and price.
