the coupler definitely ratles at a idle or moderate load,the bearing make a light grinding sound uder moderate to heavy acceleration or going up a steep hill,i have allready changed all the idler pulley'* which helped allot for noise at an idle.

have you ever heard of something GM dealerships can put in the superchrger as an apparent liquid additive that stops the bearing noise??? a local automtive parts store owner said he had this done ,and it had to be done at the dearship only ?? im skeptical

Not sure about liquid additives. But if you have bearing noise due to poor bearings, you might as well replace them. The noise will probably always be there. Fresh SC oil would help most IMO.

I see you got your info you needed

Brad there are a couple of members in the Toronto area that have to do there'* also. Depending on where you live, they may chime in and maybe we can make it a weekend event.


I can't remember who they were, but anyway let us know where you live?

There is no liquid in the world capable of fixing a bad bearing. Bearings are made of metal. Liquid is not.

I live clost to T.O and need to do my coupler and bearing...But I am limited to NO funds now. Unfortunetly it is the end of the semester I am broke and I just spent my last bit of money on go fast parts for my buick (Go Figure). I am also wondering how long my SC will last with the same symptoms it has been going on like this for about 50 000 miles.
