supercharger on 1999 Mercedes-Benz C230

my supercharger is making noise like a bearing going bad and was wondering...is this rebuildable or do I have to replace it? and who in the Portland Oregon area rebuilds these?

I'd recommend finding a replacement unit. Call your favorite MBZ specialist or get into the Portland phone book, there are companies that supply or rebuild superchargers for Diesel trucks, they might be of some help.
Myself, first thing I'd do is find out where to get MBZ parts, look in the phone book or online. Unless you're in love with that particular compressor, think about an exchange unit.
Here's a directory link for you if you want to find a MBZ specialist:

our shop has replaced several C230K superchargers. the hot ticket is from www.psesuperchargers.com; it is an exchange reman unit. everything else is just a rebuild with new spray paint. yes, you do have to replace it as
it will begin to spew oil into the intercooler, which will get inside and ruin your air mass sensor. be sure to check the supercharger clutch as well and replace it
if you have any doubt. pse is about 1/2 the cost of MB as
long as your core is rebuildable.
