Motor Mount Replacement Cost (2026): One Mount, All Mounts, by Car

Replacing one motor mount costs $200–$500 at a US independent shop in 2026, parts and labor, and replacing all the engine and transmission mounts in one visit runs $600–$1,500. Where you land depends on which mount failed (a bolt-on torque strut or a mount buried under the engine), whether it is a plain rubber, hydraulic or active mount, and how many are actually worn. Below: the price by job and by car, what the NHTSA complaint data shows, which symptoms can wait, and how to avoid paying for four mounts when one is bad.

What it costs

All figures: US independent shop, parts and labor, 2026. They are writer estimates pending review by our mechanic reviewer.

Labor runs roughly $90–$180 an hour across the US; shops on the coasts and dealer service departments sit at the top. Trucks, large SUVs, European cars and V6 or V8 engines with hydraulic mounts sit at or above the top of every row.

Cost by car

There is no trouble code for a motor mount, so the NHTSA evidence here is the complaint count by component. NHTSA files mounts under broad categories: ENGINE covers everything from oil leaks to engine failure, and STRUCTURE covers the body, frame and subframe. The counts below are all owner complaints in those two categories for model years 2008–2025. They show how often each model is reported, not how often its mounts break.

A complaint is an owner report, not a confirmed defect, and one complaint can list several components. Some of these models carry large engine-complaint counts for reasons that have nothing to do with mounts, so do not read the table as a mount failure ranking. Transverse V6 SUVs like the Explorer sit higher on price because the rear or lower mount is hard to reach. On trucks the mounts are simpler but heavier, and the engine has to be lifted further. If a shop quotes a mount on one of these models, ask whether a service bulletin under your VIN covers it; a bulletin can mean a revised part.

Signs you need it

• Clunk or bang when you shift into drive or reverse. The engine rocks until it hits the end of a torn mount. Often the first sign.
• A jolt when you step on or lift off the gas. Feels like the car was bumped from behind. Can be confused with a transmission problem; see car jerks when accelerating.
• More vibration at idle, especially in drive at a light. A collapsed mount passes engine shake straight into the cabin. If the engine itself is misfiring, that is a different job; start with car shakes at idle and rough idle.
• Rattle or knock over bumps from the engine bay. A loose engine hits the subframe; more on locating it in car rattling noise.
• The engine visibly lifts when revved in gear. Helper holds the brake hard, shifts into drive, and gives a short blip; you watch from the side, never in front.
• Oily stain or cracked, separated rubber at the mount. Hydraulic mounts leak their fluid when they fail.

Can you wait?

Yes, for a few weeks, with a mild clunk on shifting or extra vibration at idle. The engine is still held, and the repair can be booked. Drive gently: no hard launches, no towing.

Short trips only if the engine rocks a lot, you feel a bang on every gear change, or more than one mount looks torn. Each hit loads the remaining mounts, the exhaust flex pipe and the axle joints.

No, stop driving if the engine lifts far enough to change how the shifter or throttle feels, a hose, belt or wiring harness is being pulled, you hear metal striking metal, or the car pulls oddly under power. A mount that has let go completely can let the engine shift enough to damage a coolant hose, the exhaust or a CV axle (CV axle replacement cost).

What drives the price

Which mount. Most engines sit on three or four mounts: one or two side mounts, a transmission mount and, on transverse engines, a torque strut or dog-bone. The top side mount and torque strut bolt on in an hour or less. Lower or rear mounts under the engine can need the subframe lowered or the exhaust dropped, and that is where 3–5 hours comes from.

The type of mount. Plain rubber mounts are the cheapest. Hydraulic mounts, filled with fluid to damp idle shake, cost more. Active mounts, switched by vacuum or electronics to cancel vibration, cost the most and must be connected correctly or a warning light comes on.

Parts quality. Factory (OEM) mounts cost more but match the original stiffness. Cheap aftermarket mounts are often softer or harder than stock, so the car either shakes more or wears out the new part fast. Stiffer performance mounts cut engine movement but pass more vibration into the cabin.

What gets replaced with it. Shops often suggest the torque strut or the transmission mount at the same time, since the engine is already supported. That is reasonable when those parts are visibly worn, not by default.

The thing that makes it expensive. An oil or coolant leak dripping onto a rubber mount softens it, and a new mount fails the same way. Fix the leak first (oil leak repair cost). And a mount left broken for months passes the damage on: a cracked flex pipe (exhaust leak repair cost), a torn axle boot, or a stretched shifter cable.

DIY or shop?

Doable at home on some cars. A top engine mount or a torque strut on a common four-cylinder is a driveway job with a floor jack, a block of wood under the oil pan, a good socket set and a torque wrench. Parts only, figure $40–$250 per mount.

Better left to a shop for any mount under the engine, anything that needs the subframe lowered, and hydraulic or active mounts on V6 and V8 engines. Supporting a 400-pound engine on a jack while you work under it is where people get hurt.

What goes wrong: jacking on the oil pan without a wood block and denting it, not loosening the other mounts so the new one bolts in under tension (it shakes from day one), missing a torque spec on a bolt that goes into the frame, and forgetting the vacuum line or connector on an active mount.

How to not overpay

• Ask the shop to show you which mount failed. A pry bar and a helper revving in gear make it obvious. You should see the torn rubber or the movement.
• Replace what is bad, not all four by habit. A full set only makes sense when more than one is cracked or collapsed.
• Get it in writing. Which mounts, OEM or aftermarket, hydraulic or rubber, labor hours, and the warranty on parts and labor.
• Rule out the engine first if the symptom is shaking. A misfire can feel like a bad mount. A diagnostic hour ($100–$180) is cheaper than a mount you did not need.
• Get a second quote on anything over $1,000. Full-set and hard-access jobs reach that easily.
• Tell the shop when it happens: on shifting, on the gas, at idle in drive, over bumps. Not sure a quote makes sense? Paste it into the AI mechanic chat with your car and what you feel.
