Default a growling supercharger

I was wondering if anyone was selling a rebuilt front snout with new bearings complete. mine is making a slight noise and I believe the bearing might be going bad. would an additive to the oil help it, I dont believe in using nothing but the GM supercharger, but I was just wondering if there was any type of additive to maybe help just last a while I shop for a new supercharger for my 93 SSEI bonne.

Thanks for your help!

I'm not sure, but there is no play, but I think it does leak a lil oil in the front nose because I did have to put oil in it, and thank you for all your advises. I would replace the coupler with a zzperformance one anyhow if i were to find a rebuilt front nose. Thank you!

As already asked, is the supercharger only noisy at idle? If so, it'* a $36 coupler, but if it'* got over 85000 miles, you might as well rebuild the snout. If it'* over 100,000 miles, might as well rebuild the whole thing. It'* not an expensive operation, and can be done in a day.

Use a stethescope to help isolate the problem. Don't forget that on your 93, the Alternator bracket is attached to the nosedrive of the SC. This has fooled a few into thinking the SC is on the way out, when in fact it'* simply the failure-prone rear bearing of the alternator whining and growling in protest.

Consider pulling the belts one at a time to verify which belt path it'* on. Just don't run without the SC belt for too long, as it drives the water pump, too
