My wife mentioned that there was a vibration in her ML-320. I took it for a test drive and realized that the vibration was the drive shaft flopping around. The front rubber bushing or whatever it is let loose about a mile from home, making it much easier to spot.

What exactly is that part called? It looks like it centers the rear drive shaft into the rear of the transfer case. Is it a matter of pulling apart the U-joint and replacing, or is there more to it?

Thanks in advance.
