help 30 driveshaft

[fitz318is]

When my car is weighted with people and/or luggage, I get a vibration from under the car when accelerating. My car has hr sports(29664), bilsteins sports, st sways with 15 inch wheels et22. It is not a wheel vibration, its from under the car and is audable.

Mech says the symptoms point to a drive shaft which is big money.

Any one that has changed the center support bearing, what type of vibration does it feel like?

I have my driveshaft out right now for a CSB change. The vibrations went from minor, shaking the mirror, to quite severe where it felt like there was a jackhammer in the back seat. According to the driveline shop I am using to press in the new CSB, the major source of CSB failures is worn or failing universal joints so make sure you check yours carefully when you have the driveshaft out of the car.
