Sounds like the nose cone bearing are failing. Apparently you can get the replacement bearing and take the nose piece off and take it to a machine shop who will remove and replace the bearing. Just have to buy a new gasket and put it on. If the rest of the supercharger is making noise, then yes you need the whole thing reman'd. Otherwise save a grand and just do the nose cone. Do a search in usenet (use google groups) for nose cone bearing.... You will find a lot of tips and part numbers, etc. Also look on thrasher-ep for the supercharger teardown.. lots of pics. Apparently the supercharger compressor part lasts way longer than the nose cone.

Thanks, Matt. Found a lot of good info. May try to rebuild the nose cone.
I'm familiar with alt.autos.gm, but what is thrasher-ep?

Thanks! That picture of the inside of the nose piece was especially helpful.
I just ordered the kit $25 from Magnuson Products. Since my car is a 95 Park Ave ultra the seal and bearing identified in the Mavin Mller article aren't necessarily correct. Has anyone else posted the correct ones? BTW, I tried to look up the CR 7965 Seal Marvin gives in the Chicago Rawhide online catalog, but couldn't find it.
I'll post whatever I find out on the subject.
