I have a 2000 vw jetta 2.0 automatic, I wondering how you know if your dog bone (lower trans mount)bushings are no good.The mount moves whenyou rock the wheels back and forth but i'm not sure how much its suppose to move.My car vibrates pretty bad when i'm at a stop light. Also I'm having trouble with the front wobbling around 40 mph, my wheels were just balanced everything underneath feels tight.

 

If the bushings in the dogmount are cracked they need to be replaced. You can get a urathane set at ecstuning.compretty cheap. Your wheel vibration could be one of your cv joints which in turn usually destroys the wheel bearing.
