The center carrier went bad on my 2006 awd Pacifica..I have a parts car so I decided to swap out the whole drive line..in doing so I messed up the part where the rear drive shaft slides onto the front of the rearend (pinion I'm calling it)..there is a rubber coupler there with six bolts in it but that's not what I messed up..there a bushing there where a u joint would normally be,I think it presses into the back of the drive shaft best I can tell..don't know what it's actually called..does anyone know where I can get this part?

 

Welcome to the forum. Not sure of the specific answer to your question, but if it were me, I'd try to find a shop that specializes in driveshafts and take the thing over there for an opinion. Most large cities have places that are driveshaft specialists.

Failing that, try posting your question up in the Pacifica forum further down the front page.
