I'm starting to research what is involved with this repair. The car has a scary sounding rattle at cold start up but noise abates while driving.

From what I gather a partial rebuild of the pulley end of SC could solve the immediate problem but there are many parts that will eventually need attention. Full rebuild would involve the rear needle bearings (doesn't sound easy), front bearings and clutch. With all this, it sounds like any partial rebuild is short sighted and you might as well put in a factory rebuilt and be done with it.

Prices seem all over the lot. A local rebuilder has them at $1400, $2250 for a brand new OEM. My regular parts guy claims he has OEM from Mercedes for $1500. Front end rebuild kits on ebay with coupler and bearings are about $60.


Has anyone successfully done a partial/full rebuild of what I believe is a Eaton M62 supercharger?
