Engine Mount Replacement Cost for Hood Shaking at Idle in 2024

You're sitting at a red light, and you notice the hood is vibrating. Maybe it's a subtle shake, maybe it's enough to rattle your coffee in the cup holder. Either way, something feels off and after some Googling, you've landed on engine mount replacement as the likely fix. The big question now is simple: how much is this going to cost you in 2024? Knowing the real numbers upfront helps you budget, avoid being overcharged at the shop, and decide whether the repair is something you can tackle yourself.

What Causes the Hood to Shake at Idle?

Your engine naturally produces vibrations as it runs. Engine mounts rubber and metal components bolted between the engine and the car's frame absorb those vibrations. When a mount wears out, cracks, or collapses, the engine's movement transfers directly to the body of the car. That's what you're feeling under the hood.

At idle, the engine sits at its lowest RPM, and the vibration frequency is low and rhythmic. A healthy mount dampens this. A failing one lets it pass through. The result is a shaking hood, a vibrating steering wheel, and sometimes a noticeable clunk when you shift from Park to Drive.

If you're not sure whether it's actually the mount causing the problem, our guide on how to diagnose a bad engine mount causing hood vibration walks through the visual and physical checks you can do at home.

How Much Does Engine Mount Replacement Cost in 2024?

Here's a realistic breakdown of what you can expect to pay this year:

Budget range (aftermarket parts, simple layout): $150–$350 total
Average range (OEM or quality aftermarket, most passenger cars): $350–$700 total
Higher end (luxury vehicles, V6/V8 engines, difficult access): $700–$1,200+

The parts alone typically run between $50 and $350 per mount, depending on whether you choose aftermarket or OEM. Labor is where costs climb. A straightforward mount swap might take 1–2 hours of labor. But some vehicles especially those with transverse-mounted engines where the mount sits deep in the bay can require 3–5 hours of shop time.

According to RepairPal's estimator, the national average for engine mount replacement sits around $400–$600 as of 2024.

Single Mount vs. Multiple Mounts

Most cars have between 3 and 5 engine and transmission mounts. You rarely need to replace all of them at once. A mechanic will typically identify which specific mount has failed. Replacing one mount costs significantly less than replacing a full set but if one has gone bad, the others may not be far behind, especially on higher-mileage vehicles.

What Affects the Price?

Several factors push the cost up or down:

Vehicle make and model. A mount for a Honda Civic costs far less than one for a BMW 5 Series. European and luxury vehicles often have hydraulic or electronically controlled mounts that run $200–$400 each for the part alone.
Mount type. Basic rubber mounts are cheap. Hydraulic mounts filled with fluid to absorb extra vibration cost more and are common in V6 and V8 engines.
Labor rates in your area. Shop labor ranges from $80/hour in rural areas to $150+/hour in major cities. Independent shops are usually cheaper than dealerships.
How many mounts need replacing. If the mechanic finds that two or three mounts are worn, the total climbs though you save on labor by doing them in one visit.
Accessibility. Some mounts sit right on top and take an hour. Others are buried behind subframes or require lifting the engine, adding hours to the job.

Not sure if it's the engine mount or the transmission mount causing your shake? Our comparison of engine mounts vs. transmission mounts and which causes hood shake can help narrow it down before you spend money at the shop.

Should You Replace It Yourself?

If you're comfortable working on cars and have basic tools a jack, jack stands, a socket set, and a torque wrench replacing an accessible engine mount is a realistic weekend job. You'll save $100–$400 in labor costs.

But here's the catch: you need to safely support the engine while you remove the old mount. A floor jack with a block of wood under the oil pan works, but you have to be careful. Dropping an engine even an inch can damage wiring, hoses, or the oil pan.

DIY is a good option for straightforward mounts on common cars. If the mount is hydraulic, if it's buried deep in the bay, or if you're not confident in your ability to safely support the engine, pay a professional.

Common Mistakes People Make

Ignoring the problem for too long. A bad engine mount doesn't fix itself. Over time, the extra movement stresses exhaust components, wiring harnesses, and the remaining mounts. What starts as a $400 repair can snowball into $1,000+ if connected parts get damaged.
Replacing the wrong part. Hood vibration can also come from worn motor mounts, misfires, a bad idle air control valve, or even loose heat shields. Get a proper diagnosis first not every vibration at idle means a bad mount.
Choosing the cheapest aftermarket part. A $25 engine mount from an unknown brand may fit, but cheap rubber breaks down faster. You could be doing the same job again in 12 months. Spend a little more on a reputable brand.
Only replacing one when multiple mounts are worn. If one mount failed at 100,000 miles, the others are just as old. Ask the mechanic to inspect all of them.
Not checking after installation. After replacement, the engine should sit level. If the shake persists, something else is wrong or the new mount is defective.

Is It Safe to Keep Driving With a Shaking Hood?

In most cases, a worn engine mount won't leave you stranded immediately. But "safe" is relative. The extra engine movement can stress your exhaust system, cause coolant hoses to rub against sharp edges, and accelerate wear on other mounts. In rare cases, a completely separated mount can let the engine shift enough to contact the frame or damage the axle.

How to Save Money on Engine Mount Replacement

Get quotes from at least three shops. Include one dealership, one independent mechanic, and one mobile mechanic if available in your area.
Buy your own parts (carefully). Some shops will install parts you provide, though they may not warranty the labor on customer-supplied parts. Make sure you're buying the right mount for your exact year, make, model, and engine size.
Check for TSBs or recalls. Some vehicles have known mount issues. A technical service bulletin may mean the dealer covers part of the cost. The NHTSA recall lookup is a free tool to check.
Bundle the repair. If you're already doing transmission work or suspension work, adding a mount replacement during the same visit can reduce labor overlap.

What to Ask the Shop Before Approving the Repair

"Is this an OEM or aftermarket part?" Know exactly what you're paying for.
"How many hours of labor are quoted?" Compare against the estimates you've researched.
"Will you inspect the other mounts while you're in there?" A good mechanic will check, but ask to be sure.
"Is there a warranty on the part and labor?" Reputable shops offer at least 12 months/12,000 miles.

Quick Checklist Before You Commit

✅ Confirm the vibration is actually from a failing mount not an engine misfire, loose heat shield, or vacuum leak
✅ Get a written estimate with parts and labor broken out separately
✅ Compare at least two shop quotes in your area
✅ Ask if the mechanic inspected all mounts, not just the obvious one
✅ Choose OEM or quality aftermarket parts avoid the cheapest option
✅ Request a warranty on both parts and labor before approving the work
✅ After the repair, test drive and verify the shake is gone at idle, in gear, and during acceleration

Bottom line: Expect to pay $300–$700 for most engine mount replacements in 2024. The longer you wait, the more you risk damaging other components turning a straightforward fix into a much bigger bill. Get a proper diagnosis, compare your options, and don't let a shop rush you into replacing parts you haven't verified are actually bad.
