Super Charger Rattle
I have an '04 SE SC 4x4. lately on start-up i get a rattle that comes from the super charger. It does not last long and during normal driving/idling i cannot hear it. I poked around on the forum and the net and from what i am finding the issue is most likely a coupler that is worn in the unit. My X has just about 104,000 miles on it. I had the water pump, timing belt, tensioner, water pump, plugs, wires, thermostat, etc done at 96,000. It runs great other than the rattle at the moment.
I will be taking it to my local mechanic to have repaired before it gets worse. He did ask me if i was getting any whining or grinding noise which i am not. so my questions are:
1. is there a better coupler than the stock one that i should use for better reliability, etc? If so where should i get it?
2. Is there anything else i should replace in the unit while its on the bench getting worked on?
3. What oil should i use in the unit?
4. any idea on cost to do it? i know its subjective depending on what going on inside the unit but a ballpark would be good. just trying to get an idea of what to expect.
Any input wold be great. if i am not asking something i should be please let me know as well.
