I think what you mean is that the belt is squealing. All you need to do is tighten the alternator belt tension via the idler nut and toothed rail. Take the airbox out for easier access and loosen the idler bolt with a 19mm socket on the left side and a 13mm on the right. Once the tension on the bolt closest to you is loose, loosen the mounting bolt on the other side (13mm nut and 13mm bolt) just enough to tension the alternator with the toothed nut. Once you have it tightened, tighten the mounting bolts again, install the airbox and you're good. Start to finish should be about 15-20 minutes.

OK, so I just had the alternator bushings replace by the mechanic, and less than a week later, it is starting to squeal -- begins at 4k revs in first gear.

What is the driveway fix? I am going to try some silicone spray, but any other tips out there?

Thanks in advance for any help!
