i have a rattle when my bonnie idles and if i take the belt off i can turn the pully back and forth before it turns the rotors in the supercharger.i know i need a coupler but when i called the dealer they say the sc is not servicable and they don't have couplers for sale!heres my question.where can i get one and is it in the nose cone,if it is will i need to get sc oil for it too?
First of all, GM also sells the nosedrive assembly by itself for about $700.
Secondly, cramming a rag under the snout of a 94 will accomplish nothing. The whole SC must be removed from the engine to get the ND off. 96+ Bonnevilles can remove the ND on the car, 92-95 cannot. But it'* still a fairly easy job.
