Question about Dodge Charger
Harmonic balancers can cause heavy vibrations also motor mounts (which think it is. Chrysler was famous for it in those years) oil will leak down from the valve covers and soften the rubber and the torque from the engine will snap the mounts and shift the engine. Easy way to check the mounts is to open the hood, start the engine and put into drive. Hold your foot firmly on the brake pedal and slowly give it the gas. If the mount is broken the engine will raise up on the left side. Then put the car in reverse and do the same thing, if the other mount is broken the engine will raise on the right side. If the balancer and mounts are OK then you might have a cracked flywheel. To check remove the retaining bolts on the transmission torque converter push the converter away from the flywheel and start engine if vibration is gone the flywheel is cracked.

The harmonic balancers entire job is to keep the engine at a perfect idle at any speed.
as the engine vibrates due to faulty harmonic balancer.
if it misfirs and vibrates together then its fuel pump problem.if you are getting white or black smoke at the engine with vibrating that means its crank shaft sensor problem .
but nothing like that then its harmonic balancer for sure.check out properly.
pleaske do rate the solution.keep updated.

It is unlikely that your problem is caused by internal parts, if anything broke internally, you would know right away. The harmonic balancer does bolt to the crankshaft, and therefore could be a source of vibration.
The best way to know is to take the belts off, and start the engine and rev it a little bit, if you still have vibration, then pull the balancer off, and again start the engine and rev it a little bit.
Caution: The water pump requires a belt to operate, and therefore do not prolong these tests, keep an eye on the engine temp.
You might want to look at your spark plugs and wires. A grounded wire will cause the engine to run rough.Pull the plugs and check for cracks or shorts. replace them if you can afford it. Its difficult to see a bad wire, if you can afford to replace them, do it.

The power impulses of an engine result in torsional
vibration in the crankshaft. A vibration damper mounted
on the front of the crankshaft controls this vibration . If this torsional vibration were not controlled,
the crankshaft might actually break at certain speeds.
Most types of vibration dampers resemble a
miniature clutch. A friction facing is mounted between
the hub face and a small damper flywheel. The damper
flywheel is mounted on the hub face with bolts that go
through rubber cones in the flywheel. These cones
permit limited circumferential movement between the
crankshaft and damper flywheel. That reduces the
effects of the torsional vibration in the crankshaft.
Several other types of vibration dampers are used;however, they all operate in essentially the same way

Inspect your engine while it's running. Listen for any sucking or hissing sounds, which might indicate that an air hose or vacuum hose is loose or disconnected. If you find loose or disconnected hoses, reattach them and see if that solves your problem.
Listen to see if your engine is missing. An engine that is missing can cause a vibration because one or more of the cylinders are not firing. If you believe that you detect a miss from the engine, pull out a few spark plugs and look at their condition. If they are very dirty and worn, change them and see if this stops your engine from missing
Inspect your ignition wires. See if they are cracked from the heat of the engine. Make sure that they are tightly connected to the spark plugs and to the distributor. A good way to see if they are defective is to put the car in gear, and while your foot is mashing the brake, rev the car and see if it starts missing. This is a good way to put a "load" on the engine to see if the wires hold up.
Check from underneath the engine and look at your engine mounts. These are the thick rubber blocks that are between the chassis and the engine. Sometimes they are filled with hydraulic liquid. If so, make sure it isn't leaking. Check your mounts by inserting a crowbar between the engine and the chassis. Put pressure on it, moving the engine away from the chassis. If you see that the motor mounts are cracked or damaged, you may want to take your vehicle to an automotive technician to have your motor mounts replaced
Check your harmonic balancer. Harmonic vibrations can lead to a variety of mechanical failures. Harmonic vibrations are specific and usually have a repeated type of vibration which ebbs and rises. One indication of your harmonic balancer being worn is if you detect a leak from your front main seal. If the above steps don't fix your problem, take your car to a professional and have them check the harmonic balancer.

Either you have a warped pulley, or your vibration damper may have low fluid.

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.
