Huge engine vibration

The engine vibrates hard and when I asked the dealer they said it was a factory problem with the harmonic balance. I took it to my mechanic who looked it over and said it was the motor mounts. who is correct? I don't see any issues regarding the harm. bal. anyone have any ideas?

What is the make and model and year? When does the vibration happen? Certain speed or tach reading?

    1997 ford escort lx-4 door automatic the vibration starts when in park and at a stop light

    This is most likely the harmonic balancer. It could be the torque converter though

I don't think so.They seem to be on top of the situation more than the dealer for 1 thing.For vibration,I don't really think a compression test would show anything.That would be more of a loss of power issue.If that shop did not think the other 2 mounts were bad enough to require replacement,the answer is probably somewhere else.If this is an automatic,when do you put it in neutral?At lights or long stops?I would like to know the answer for that please.It could just be the age of the car and normal wear and tear is causing it but if the vibration is bad enough to post here,there could be something.I have a 1995 Escort wagon with 135k miles and it shakes a little bit.Anyhow,just comment here and I will get an aoto link back here to see what you said.

SOURCE: I've changed my engine mounts 3 times on my 2004 A4 cabreolet and they fail within miles(start to vibrate & then within a week, severe knocking) the 2nd time, also changed the ****** mount, 3r

Engine mounts do not go bad in five miles. Sounds like you're treating a symptom and not the cause of a more serious issue. Are you sure all cylinders are firing correctly? That the severe knocking is not coming from your engine internals? Have you checked the steel around the engine mounting points for cracks or other damage? And just in case, if the mounts you are using are poly, are you lubing them before installation?

SOURCE: FRONT END VIBRATION

The dealer is not going to replace something if they can not prove to the company the part is defective. The company won't pay the warranty claim.
A bent axle was my next guess. A garage could find out by using the same dial indicator used to check for a bent rim.
The dial gauge is placed against the shaft and the wheel is turned, if the axle is bent the dial will move.
I don't know what Road Forced balanced means, but most balancing machines duplicate road speed of about 30MPH. So a tire or wheel can balance ok on a machine but still have a vibration at speeds above 30 or 40mph. The easiest way to make sure is move the front tires to the back and see if the vibration travels too.
If you are describing the problem correctly, it almost has to be in the transmission, the axles, or the wheels. There is a slight chance a strut or strut mount could be faulty and allowing a small bounce to be amplified.

SOURCE: engine vibrates when car is in gear

have you done any other work, trans mount, recheck all bolts, exhaust has its flex pipe? I may be wrong but front and rear mounts are sloted are they set properly, also top side mount have two big washers or insolators on each side are there missing? this will cause a vibration. good luck

How to replace a Dorman Harmonic Balancer on a 2001 Chevy venture van


What is a Harmonic Balancer?
The Harmonic Balancer, or vibration damper, is a component connected directly to the front of the engine on the crankshaft. Its sole purpose is to reduce torsional vibrations created by the engine as the cylinders fire.

What causes Harmonic Balancer failure?
There are a variety of possible causes for balancer failure. Most common among these are heat stress, wear from road salt, oil leak, or ozone attacking the rubber components, damage inflicted by road debris, crankshaft failure, stress from integrated drive pulleys, and stress caused by loads from other devices such as power steering pump, AC compressor, alternator, air pump, and water pump.

Why is the crank pulley dampered?


No, you do not want to replace the crank pulley with a solid one. The hub is also know as a Harmonic Balancer. The explosions that happen inside of your engine cause vibrations or harmonics, the balancer greatly reduces these vibrations. Without the ruber insulating ring the harmonics can cause part failure at certain frequencies.

What damage does harmonic balance that is bad do


The harmonic balancer is basically a vibration dampened for the engine to eliminate engine vibration. The problem is that sometimes the actual ribbed pulley part on the balancer will separate from the rubber insert and slop around causing the belt the slop around with it. In turn the belt can fray or break. I would say its totally legit what they are saying. Just make sure you always ask to see the part after any work is done. Good luck

If the harmonic balancer wobbles when the engine is running, it could cause a vibration. A typical balancer has a rubber seal between the balancer and the belt drive pulley. The rubber seal may have deteriorated.

Hi guys, I come to you with an issue on my 1985 Buick LeSabre collectors 5.0 V8. Well, the issue is that it the engine will shake the car when trying to stop. Could it be the engine harmonic balancer? Or...


Is the vibration only occurring when you turn the vehicle off? If so, it is not the harmonic balancer. The way they work is tp stop the vibrations of your engine from causing crank shaft failure. When this device is not working to its full potential, the vehicle vibrates and sounds awful as soon as you start the engine.

2004 GMC Safari Motor Vibrates


exhaust resonance is unlikely
vibration is caused by something spinning that is out of balance
it can also be from a misfire or a mechanical problem
considering the mechanical problems
harmonic balancer - replaced delete reference unless loose bolt
loose clutch pressure plate --no information as to auto or manual--possible
cracked flex plate--no information as to auto or manual ---possible
failing cam shaft lobes --cam nobes wearing off causing valve timing problems --very possible
faulty hydraulic lifters --pumping up and holding a valve off the seat -possible
hydraulic follower failure --excessive valve clearance altering valve timing --very possible
ignition timing too far advanced -- tune up should have checked that but is a possibility
failed water pump bearings --noisy but a possibility
viscous fan hub ( if not electric fans )-- a distinct possibility--bearing failure and fan running off center-off balance
injectors --- any injector squirting but not the same amount as the others will cause a harmonic unbalance --possible
except for the cam shaft as mentioned , the engine has done 30.000 miles so any fault in the rebuild would be shown up before that mileage was done
drive line problems ---unlikely as you state it vibrates when stationary and that confines it back to the engine and transmission
only parts spinning are the engine parts and the input shafts , torque converter or clutch

Hi,

vibrations over 55 mph are usually balance related (tire balance, drive shaft balance, motors)

vibrations at lower speeds are usually mechanical (bent rims, out of round tires, bad tie rods)
Therefore the suggestion for checking the harmonic balancer is perfect in your case.

Thanks
