A little more help if you're unfamiliar with the realoem site.
Enter the last 7 of the vin, like Marcozandrini recommended. Go to rear axle, and scroll down to rear axle carrier. For my car, it was part number 9 on the diagram.
From there you can get the part number.
I used the Myle HD bushing, and FCPeuro has a lifetime warranty on parts.
A little forewarning, this job is a major pain. BMW has a special press tool to get it in and out. I recommend an air hammer with a few different chisel heads. Be very careful not to hit the aluminum carrier.
You can pound the new one in and use a ball joint style press to get it in.
