I got a drive shaft at a junkyard for a Chrysler Cordoba. You know the one with the fine Corinthian leather? Mine had fine Corinthian vinyl. So I paid this guy to install it. He said he was s mechanic. About 3 weeks later I'm driving down Goodwood Blvd with a hot chick. We had been drinking. Heavily. As soon as I turned onto Tara Blvd the drive shaft fell out. I wanted to murder the so called mechanic. Very slowly.
Why? A driveshaft isn't easy to break. Guess I misunderstood our conversation. Now I'm worried about the bearing. You shouldn't need to replace the shaft.
Get used. They shouldn't go bad unless its at the point of connection, which you should be able to see.
Got a used one. 4 bolts and was good to go. U joints came with it. Drives much better without the vibration.
