Hi… I was told that I need engine mounts replaced. One front, one side. How much work is involded?

Was told that I need engine mounts replaced. 1vfrobt, 1 side. Is it better yo do all mounts or just the 2.

My car has 180000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Mounts are rubber based products and thus have a decidedly fixed lifetime. Failures and deficiencies in these parts can cause vibration within the vehicle and also result in mis-positioning of the drive axles causing premature wear-out of the axles. Technically then, the best strategy is to replace all three mounts, if even one is bad, as the remaining mounts are clearly going to be well used at minimum. With regard to the work involved and the cost, you can obtain a detailed, written quote for your year, make and model, by using YourMechanic’s motor mount replacement service page.

How to Identify and Fix Common car Problems ?

What Happens if I Don`t Change my Motor Mounts? If an engine mount breaks off from an engine, there will no longer be effective support. Damaged components can create a safety hazard for yourself and other motorists if other components break or fly off due to engine mount wear.
In principle, yes you can. However, when a mount starts to fail it puts more load on the others. Since they`re the same age as the failed mount and are now working harder, they`re likely to fail soon too. So while the car is in the air and the engine supported, it probably makes sense to replace them all.
If you fail to replace your engine mounts when they are breaking, your entire car might suffer damage. With the heavy engine shifting under the hood, it can knock into other vehicle components. Naturally, this also causes unreasonable wear and tear on the engine and transmission.
As motor mounts deteriorate and give your engine wiggle room to move, you may hear strange noises under the hood. Thumping or clunking could be impact sounds from the engine making contact with other components during acceleration.
A failing motor mount can lead to serious engine damage and will also greatly impact the performance of the vehicle. It is very unsafe to drive with a broken motor mount. If you feel a lot of vibration in the vehicle while you are driving, there`s a good chance it`s the motor mount.
Motor mount replacement is a big job, though, so be wary of any mechanic or dealer that is offering to do the job for a price that seems too good to be true.
Typically, one motor mount fails before the others. As an engine revs, it wants to rotate in the same direction as the crankshaft. That tends to stretch one motor mount and compress the others. Usually, the mount that stretches is the one that fails first, Mazor said.
Positioning the mount incorrectly also can make it impossible to line up bolt holes, or you could experience unusual driveline conditions such as a heavy banging when you go over bumps caused by the driveshaft`s slip yoke slamming into the transmission`s tailshaft.
Even with these steps, you will not be able to extend the life of the engine mount significantly. In summary, engine mounts last between 5 to 7 years. Symptoms of bad engine mounts include excess vibration, impact noises (thud/clunk), and misalignment of the engine.
Mounts can be visually inspected for cracked, loose or broken brackets, loose or missing bolts, collapsed rubber or fluid leaks (hydro-mounts). A pry bar can be used to check for separated or broken mounts.
Broken engine mounts are no longer capable of absorbing the vibration from the engine; typically meaning the rubber guards are ineffective. The vibration is very noticeable inside the car, especially from the passenger`s seat. However, the steering wheel and dash are also likely to shake.
So if one of your engine mounts is broken or badly worn out, you`ll feel the normal vibrations of the engine much more strongly. And you`ll notice it most at idle, when you don`t have all the other wonderful road noises and vibrations to distract you.
As mentioned, a failed motor mount may make a clunking or banging noise and/or you may feel the engine shift and you might hear the fan hitting the shroud on a rear-wheel drive vehicle with a broken mount.
Typical vehicles have between three and four motor mounts depending on their size and the stability of their engine. Certain cars may have four mounts due to how the engine is positioned relative to its other car body components and vice versa. Again, your car`s manual will likely contain these details.
For a motor mount that is right on top of the engine it may only take 30 minutes for a mechanic to swap out the old mount and replace it with a new one. If the motor mount is buried in the engine bay, you may be looking a two or more hours to gain access. That translates to a labor cost of $100-$450 per mount.
Here are some of the common reasons for rough idle: Motor mounts: It`s the job of the motor and transmission mounts to dampen vibration. When they break, you`ll feel excessive vibration, especially at idle. You can diagnose this yourself by putting your car in neutral.
A torque wrench is the tool of choice for tensioning the engine mount fasteners. For the final adjustment (after alignment and load equalization have been done), use two wrenches/spanners: one to hold the adjusting nut steady and the other to tighten the lock nut. This will ensure proper tension between the nuts.
Signs of a Broken or Loose Motor Mount

Over time, it`s fairly common for the engine mounts to weaken. In some severe cases, a mount can even snap. If any of the motor mounts aren`t securely keeping the engine in place, it will cause problems and it can make the vehicle very dangerous to drive.

Engine mounts are made of a hard rubber material which allows them to absorb these vibrations. When a motor mount is damaged or broken, not only will you feel excess vibration in the car, other parts in the engine can get misaligned and ultimately break since the engine is not in its precise location.
Motor mounts are made to hold your engine in place and absorb vibration. If your engine is shaking in place, it`s probably a sign of bad motor mounts. In extreme cases, the excessive vibration can be felt when sitting in the vehicle, particularly from the passenger side.
Engine misfire could be caused by worn or broken motor mounts that raise the motor on one side while the vehicle is accelerating. The stress on the engine control wiring harness can cause breaks in the injector or sensor wires, which then causes drivability concerns such as poor fuel economy and engine misfires.
Broken engine mounts are no longer capable of absorbing the vibration from the engine; typically meaning the rubber guards are ineffective. The vibration is very noticeable inside the car, especially from the passenger`s seat. However, the steering wheel and dash are also likely to shake.
The rubber or liquid-filled portion of the motor mount helps absorb vibrations from the engine. As such, when one or more motor mounts fail, vibrations from the engine may travel through the chassis and into the cabin of the vehicle.

Engine and Transmission mounts have collapsed. Do they have to be replaced immediately? How much for both? TBC….
ANSWER : If the engine mounts are faulty, the drive axles will operate at the wrong angle eventually causing premature wear-out of the axles so it is important to get the mounts replaced. If you would please refer to YourMechanic’s motor mount service page you can obtain the requested price quote. Brake pads generally cannot be replaced without either resurfacing the brake rotors or replacing the rotors if they are not restorable. If you do not follow this procedure the brake pads will wear irregularly, wear out early and you may get brake pedal pulsation and vibration from rotor thickness variation. To request brake service and cost info, please use YourMechanic’s brake pad/rotor service page. With regard to your air suspension, repairing a leak is typically straightforward but, as noted, the status of the whole system, whether you need a new dryer, and so forth will have to also be determined. If you request an air suspension diagnostic the mechanic can just deal with what you have in one trip and estimate for you, on site, all the repairs that are necessary. Of course, if the simple leak repair resolves everything, there will not be a need for further estimating. If you schedule the aforeforementioned mentioned services, the responding certified mechanic will get this taken care of for you.

When should I replace a motor mount on a 2004 kia optima?
ANSWER : Hello. The motor mounts on vehicles in general should be inspected every 50,000 miles. I’ve seen motor mounts become excessively worn on vehicles with as low as 30,000 miles so it wouldn’t be a surprise if yours are due for replacement at 60,000 miles. The main part of motor mounts and made of rubber and sometimes the rubber what the teary rate quicker than average depending on the types of elements its exposed to (heat,cold,vibrations,and rough driving are elements in which a motor mount will be exposed). I would say the book time for the motor mount replacement is about an hour and a half. I will get a quote sent to you regarding the labor cost.
To replace the crankshaft position sensor yes you will have to remove the motor mount, power steering pump and the timing belt. The crankshaft position sensor should be a 2.5 to 3.5 hour job. Technicians here at Yourmechanic could provide the repairs for you if requested.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

How do you replace the rear & side engine mounts without lifting out the engine? & how do you lift the engine out?
ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page.

Hey Allen. I just rebuilt (?) the engine on my 06 Acura TL. Now the engine line went on. They told me the engine? can blow up if I
ANSWER : Hi there. I think it may be a good idea to find a new mechanic. Fortunately, our mobile mechanics are able to complete most diagnostic inspections and complete a lot of repairs services at your location, and on your schedule. In what you are describing above, the current issue seems to be with your EVAP system, which is designed to relieve pressure in the fuel tank and also collect harmful vapors before they escape into the air. Now, in regards to the car "blowing up"; that’s a bit dramatic, but it is important to have your issues repaired if it’s related to the EVAP system. Here is what I would recommend. Set up an appointment to have one of our mobile mechanics come to your location to complete a check engine light inspection – (click here to set up an appointment). This will allow them to download the stored error codes that cause the light to illuminate and determine what parts need repair or replacement. Then, they’ll be better prepared to provide you with a repair estimate and complete the repairs in most cases for you.
