new problem i was drive down the road and all the sudden i hear a really loud squeaking that started getting worse coming from middle of the car. i get home pull straight pipes and h pipe off and i turn the drive shaft my hand and the squeaking starts if i left up on it and turn it it stops its coming from a rubber thing that looks like a drive shaft support right in front of the second u joint where the to shafts connect what is it and how do i fix or replace it.

 

Yes it's a center support for the driveshaft. Below is a writeup on changing it.
