What engine mounts do
Engine mounts hold the engine and transmission in place and absorb vibration. Most are made of rubber bonded to metal brackets, and some are filled with fluid or controlled electronically to reduce vibration further. A typical car has several mounts, including one or more that support the transmission.
Signs of a worn mount
- Strong vibration at idle, felt in the steering wheel, seat or floor.
- A clunk or thump when shifting into drive or reverse, or when accelerating and braking.
- The engine visibly moving or rocking when someone revs it with the hood open.
- Cracked, collapsed or oil-soaked rubber on the mount.
- Fluid leaking from a fluid-filled mount.
Why the cost varies
The price depends on which mount has failed and how hard it is to reach. Some mounts are on top of the engine and come off in minutes. Others are underneath and require supporting the engine with a jack while the mount is removed. Fluid-filled and electronic mounts cost more than solid rubber ones.
Why it matters
A failed mount lets the engine move more than it should. That puts stress on the other mounts, the exhaust system, hoses, wiring and axles. On front-wheel-drive cars, excess engine movement can contribute to CV axle and exhaust problems. Replacing a worn mount early prevents those knock-on repairs.
One mount or all?
If one mount has failed and the others are the same age, they may be close behind. Ask the shop to inspect all of them and show you the condition of each. Replacing only the failed one is fine if the others are in good shape.
Can you do it yourself?
Some top-mounted mounts are an easy job with basic tools. Mounts that require supporting the engine are best left to a shop with the right equipment, because a slipping engine can cause injury and damage.
Questions to ask the shop
- Which mount has failed, and can you show me?
- What is the condition of the other mounts?
- Is the replacement mount solid rubber, fluid-filled or electronic, and does it match the original?
How the job is done
- The mechanic checks each mount by watching engine movement while someone shifts between drive and reverse with the brake held.
- The engine or transmission is supported with a jack or an engine support bar.
- The bolts holding the mount to the frame and the engine are removed, and the old mount comes out.
- The new mount goes in, and the engine is lowered so it settles naturally before the bolts are tightened to specification.
- On cars with electronic or vacuum-controlled mounts, connectors or hoses are reattached.
- The car is road tested for vibration and clunks.
Frequently asked questions
Can I drive with a broken engine mount? For a short time, but the extra engine movement strains other mounts, hoses, the exhaust and axles. A completely failed mount can let the engine shift excessively.
Why does my car vibrate more in drive than in neutral? Worn mounts often transmit more vibration when the engine is under load in gear. This is a classic sign of a failing mount.
How long do engine mounts last? It varies with driving conditions and heat. Oil leaks onto rubber mounts can make them soften and fail sooner.
Do transmission mounts count as engine mounts? They are part of the same system and are often checked and priced together.
Is your quote fair?
Compare your written quote with the national range above. A quote well above $798 is not automatically wrong, because some vehicles need more parts or more hours, but it is worth asking the shop to explain the difference. Ask for the quote to be split into parts and labor, and for the parts to be listed by name and brand. If the labor portion is far above $481, ask how many hours the shop is charging and what makes your car take longer. Getting a second written quote for the same parts is the simplest way to check a price.
What happens if you wait
A broken mount lets the engine rock more than it should. The extra movement strains the remaining mounts, which then wear faster. It can also stretch or crack hoses, pull on wiring, stress exhaust connections and, on front-wheel-drive cars, put uneven load on the CV axles. In extreme cases, the engine can shift enough to damage the radiator fan or other parts.
You may feel more vibration at idle, hear clunks when shifting between drive and reverse, or feel a jolt when accelerating or lifting off the gas.
Replacing one mount or all of them
Most cars have three or four mounts, including the transmission mount. If one has failed because of age, the others may be close behind, since they experience the same heat and wear. Replacing all of them at once can save labor if they are accessible from the same position. If only one failed due to an oil leak or an impact, replacing just that one is reasonable. Ask the shop to show you the condition of each mount.
Fixing the cause
Oil and coolant leaks soften rubber mounts. If a leak is dripping onto a mount, fix the leak at the same time, or the new mount will fail early.
Choosing mounts
Ask whether the quote uses original-equipment or aftermarket mounts. Some aftermarket mounts are stiffer and transmit more vibration into the cabin.
