    Hi
    I would need to be there and feel the vibration to have any chance of figuring out what the cause is. When does it do this at idle? What is the make, model and year and engine type and size

Check for the drive joint phasing and angle setting of the center bearing
mostly with center bearing , the drive shaft has to be split and the flange removed for the bearing replacement
the flange can be put back on in any position and that will throw out the s joint phasing
Take it to a drive line specialist shop and ash them to check the phasing and angles to eliminate the vibration
The vibration could have been from a bad joint and the new joint was not properly installed which will also vibrate
If you are not familiar with the term phasing It is when the joints are in direct line with each other when placed on a flat surface and allows the differentiating speeds of the crosses as they pass through the 90 degrees to cancel each other out and stop the vibration
the drive line specialist will know and explain it better as he will have the drive shaft to show you on

You done everything else. Only thing really left is balancing the drive shaft. Should have been done way before you replace the engine and transmission mounts.

SOURCE: Noise and Vibration

I replaced the lower passenger side engine mount and the vibration is still there but a bit less vibration. The lower passenger mount was worn out. I was told by the Dodge service dept that it takes 5 hours to change the main hidden engine mount which is mid way up the passenger side of the engine. That main hidden mount cost 75.00

To get to it you would have to remove the wheel, inner fender plastic work, windshield washer fluid tank, and etc.

SOURCE: vibration on the engine, change motor mount all

Check the idle control system, also check if all the injectors are working. Provided you already changed the spark plugs.

SOURCE: 2001 Impala,

Has to be a drive axle,most likely an inner joint,should be able to feel the play if one is bad (jacked up to let the wheel spin freely).
Also. If the front suspension is weak,or lowered, the CV axle will bottom out in the inner plunge cup and make a terrible vibration.

Testimonial: "You Called it !! Both axles were worn out at inner joint left boot blownout dry barings, right axle needle barings gone,baring floating around inside"

SOURCE: my 2003 honda crv vibrates

Without driving the vehicle, it is hard to say for sure. However, there is a Technical Service Bulletin (TSB) that is published by Honda that involves your transmission limiter tabs (part of the rear transmission mount) causing a vibration while accelerating.
The TSB number is 04-070. I can send you a complete copy of the TSB if you want to post an email address. Or you can also probably get your local dealer to print you out a copy if you don't want your email address posted online. (recommended)

2009 I4 Ford Fusion has terrible vibration throughout the steering wheel and front seats a lot of maintenance has already been done

The vibration might be caused by anything connected to the road wheels. If it only happens when the car is in one of drive modes it could be something between the transmission and the tyres. Start at the wheels and work in towards the gearbox. Try this checklist.
**Note** Apply these checks to ALL 4 wheels.
-Tyres. Are they inflated correctly? Are they in good condition?
-Wheel Rims. Are they undamaged? Are ALL the wheel nuts tightened correctly?
-Tracking. Is the Toe in, camber and wheel alignment correct?
-Brakes. Are the pads and discs OK? Discs can warp and cause vibrations.
-Wheel Bearings. Worn bearings are noisy and can collapse.
-Drive Shafts. They usually need balancing when they are made.
-Suspension Mounts and Arms. Worn mounts and ball joints move creating noises. Are the springs and dampers working correctly?
The All Wheel Drive version will need the propeller shaft checked for balance and the rear differential and shafts should be checked and serviced as well.
If none of these give you the source of the problem your possibly looking at gearbox issues.

My Pontiac Torrent 2007 has a vibration at 60mph. Tires have been balanced and the front drive shaft and centre u-join. Not sure what to check next. Can you make a suggestion?

Gearbox mount might be worn, my car did the same thing at a certain speed.

First I changed differential oil and gearbox oil, helped a little but didn't solve it.

Then changed gearbox mounts and that worked for me. Not sure your problem is the same tho.

You hear any noises just before vibration starts?

Lancer vibrates at 90 to 100 ks at front at front left

bent rim, tires out of balance, worn cv axle, bad wheel bearing, warped brake rotor, bad tire. Change that wheel to the rear, and see if the vibration moves with the wheel. Depending on the vibration, could be a motor/transmisson mount.

I have a bad vibration between 35 mph and 70 mph however if I take my foot off the gas the vibration goes away - have changed fuel pump, filters and engine mounts and now the esp light comes on and goes...

vibrations can come from all manner of things, wheel imbalance thrown a weight or flat spot on tyre or damaged wall, suspension mounts, engine+gearbox mounts, anti roll bar mounts, wishbones lower mounts, drop links, steering rack and idlers, there can be others that you would not think can do this and these are clutch thrust bearing or plate spring. rear wheel drive prop shaft mounts, exhaust and mounts, automatics can be the torque converter out of balance. also can be worn bearings on the wheels. you would need to find were the location of the vibration starts and pin down its area this can help with another pair of ears in the vehicle.

I was advice to change the long shaft coupling some time ago. I realised there is some vibration when doing 90km. recently I was advice to change another coupling along the long shaft, which makes it...

Things that go wrong on this propshaft:
Centre bearing. A bearing mounted in a rubber housing in the centre of the vehicle. Inspect the rubber for cracking and tearing. Replace if worn. The bearing itself rarely wears out before the rubber mount.
Universal joints - there are 3, one at the differential in the rear of the car, one at the center bearing and one at the transmission in the front of the car. When worn you will hear a distinct metal "clunk" when taking up drive on pull-away. Check by gripping the shaft either side of the joint and twisting eah side in opposite directions. There should be absolutely no play in the joint. Replace if worn.
Whenever a joint is replaced it is nescesary to have the shaft balanced again.

could be a bearing failure so check for metal in the oil
normally with bearing failure you will have other indications like gears jumping out , growls , grinds difficulty in selection 2,3.4 and over drive

Vibration through car

If you don't have to be moving to get the vibration then it has to be either something is not balanced properly (torque converter may be bad, front pulley, engine flywheel cracked) or you have a bad mount, causing the vibration from making the engine or trans contact the car body in a place you can't see.
Hard to pinpoint without feeling it myself. I can say for sure it's not the cam belt, unless there's debris stuck to the inside of the cam gear causing the vibration.
