Is the shaking felt in the steering wheel or in the seat of your pants? Is the engine running rough causing it to shake and have lack of power? Is the Service Engine Soon light on? Please reply with a bit more informaiton if you can.

Which one? The cv or half shaft??
ANSWER by , February 12, 2014
the simple visual chekup,....go in front of the car, lay down and look under the car, if the transmission oil pan is below the sub frame or (engine crate)....u need mainly bottom engine and transmission mounts....this situation creates shaking and vibration of the front end.....also if the mounts have been bad for along time it can create damage to the transmission differential, by the transmission hanging low on the engine side motor mount,.... meaning the axle hang to low now and rubs against the engine sub frame.

could be a bad engine/transmission mount, but mote likely a cv joint is failing, i would suggest replacing both drive axles with quality replacements, new rather than rebiult if your wallet allows is the better investment

Car would shake between 30mph & 50mph. Previously put new tires, balanced twice, rotated 3 times and still shook. I changed the driver side half shaft. thought that was it, but still shakes, between 30mph through 50mph then as smooth as butter. What if I change passenger and it still shakes. This is driving me crazy. CV Joints fine.
