Engine mount replacement costs $643–$798 in RepairPal’s national estimate, before taxes and fees. Your price depends on which mount failed, its design and access, and whether the estimate covers one mount or several. Ask for the position and part number before comparing totals; a single-mount price cannot price a complete set.
The useful comparison is a mount-by-mount worksheet, followed by a check that the proposed repair addresses your actual vibration. A manufacturer bulletin can change that plan, particularly when installation position or settling is part of the complaint.
How much does engine mount replacement cost?
Use published estimates as a starting point, then compare the exact vehicle and repair scope. RepairPal’s estimate, last updated September 3, 2026, separates $328–$481 labor from $316–$317 parts and excludes location-specific differences, taxes, fees and related repairs.
YourMechanic’s engine or transmission mount page provides these vehicle examples, checked October 2, 2026:
| Vehicle named by source | Parts (USD) | Labor (USD) | Published estimate (USD) |
|---|---|---|---|
| 2010 Dodge Charger | $212.92 | $481.76 | $695 |
| 2012 Audi A3 | $329.94 | $788.34 | $1,118 |
| 2015 BMW 335i | $280.95 | $715.35 | $996 |
| 2015 Ford F-150 | $940.55 | $656.95 | $1,598 |
The page labels the service engine or transmission mount replacement and does not identify mount positions or quantities in these rows. Its rounded estimate can differ slightly from the sum of displayed cents. These are source examples, not Accelerate’s prices or interchangeable bids for your car.
Does the quote cover one engine mount or all of them?
The written quantity and positions should settle that question. Ask the shop to replace a line reading only “motor mounts” with the actual locations, part numbers and individual findings.
Use this worksheet when one estimate is for a single mount and another is for a set:
| Estimate field | What to write down | Why it helps |
|---|---|---|
| Position and quantity | Each engine, transmission or torque-support mount proposed | Establishes whether both bids cover the same work |
| Finding at each position | Damage, fluid loss, movement or application-specific test result | Connects each purchase to a reason |
| Part choice | Manufacturer, part number and design | Makes substitution visible |
| Labor scope | Access work, support, installation and final checks | Explains what the labor buys |
| Additional mounts | Required by procedure, failed independently, or elective | Separates necessary work from a convenience choice |
| Total due (USD) | Parts, labor, diagnosis, hardware, tax and fees | Lets you compare an actual bill |
Choose a single-mount repair when the diagnosis identifies one failed position and the applicable procedure supports that scope. Choose a paired or broader repair when findings or manufacturer instructions support the added positions. Request both versions of the estimate when the additional work is elective.
Why do hydraulic and active engine mounts cost differently?
Their design does more than hold the engine in place. AutoZone’s mount explanation distinguishes rubber-and-metal mounts, fluid-filled hydraulic designs and electronic active mounts that adjust damping. Hydraulic designs add complexity; access also changes replacement labor.
Ask whether a lower-priced option preserves the original design and connections. For a car bought for a quiet cabin, price the repair against that goal. A mount that fits the bolt holes still needs to be suitable for the application and the comfort you expect.
When comparing parts, request the actual part number rather than accepting “premium” as a specification. Ask who supplies the part, what the written parts-and-labor coverage is, and how an unresolved vibration will be evaluated after installation.
Can vibration at idle prove the engine mount is bad?
Vibration is a reason to investigate, not enough information to order a mount. AutoZone warns that a misfiring cylinder can also produce severe engine vibration. If a warning light accompanies the shaking, the check-engine-light guide explains the separate diagnostic path.
Describe when you feel it: cold or warm, stopped or moving, in Drive or Neutral, with air conditioning on or off, and before or after another repair. Bring that record to the inspection. Have the technician explain how the finding connects to your complaint before you approve replacement.
There is a useful vehicle-specific example. GM bulletin 17-NA-166, September 2019, covers specified Cadillac, Chevrolet and GMC trucks/SUVs with listed engine codes and model years. It describes an idle-in-Drive concern without diagnostic trouble codes, requires vibration-frequency analysis, and separates earlier-build updated-mount replacement from later-build shimming procedures. The earlier-build procedure includes both engine mounts and settling the mounts.
That bulletin does not diagnose every Silverado or every rough idle. Ask whether your VIN, engine and build date fall within a current applicable procedure. It shows why “it shakes, replace one mount” can miss the actual repair scope.
Is replacing engine mounts worth it on an older car?
Compare the confirmed repair with the car’s wider condition and your ownership plan. A mount estimate by itself says little about whether the engine, transmission and body are otherwise worth keeping.
Before deciding, ask for the minimum supported repair, any procedure-required companion work, and a separate price for elective work. Add other known near-term repairs to your budget. Paying for a correctly scoped repair can make sense on a useful car; paying for a set without an explanation gives you little basis for the decision.
Common questions
Are motor mounts and engine mounts the same thing?
Yes. AutoZone uses those terms for the same component category. Ask separately about transmission mounts when the estimate includes them.
Should I order the cheapest mount myself?
Get the exact application and part recommendation first. Also ask how customer-supplied parts affect the shop’s written coverage and responsibility if the vibration remains.
Can I safely wait a month?
An inspection should determine urgency. YourMechanic warns prolonged driving with broken mounts can damage axle shafts and the transmission. Ask whether your particular finding requires parking the car or permits travel to the appointment.
Will a mount replacement fix every vibration?
The promised outcome should match the diagnosed complaint. Ask how the shop will reproduce and check that complaint after the work, particularly when more than one vibration is present.
What if the car started shaking after mounts were replaced?
Return with the invoice and describe the change. Request a check of part application and installation against the manufacturer’s procedure before purchasing another set.
Bottom line: Compare the exact mount positions, parts and diagnosis first; approve a single mount or a set according to the findings and vehicle procedure, then have the original complaint checked again.
