I have a very strong belevie that one of my pully bearings is going bad. I was wondering if any one konws of one that may comonly go bad like this. the sound I hear is the cerpantine belt sliping. so I titend it and put some belt dressing on it and that did nothing. so I deffinatly thing that it could be a pully resisting the belt. the other day I had the car on and it wasnt making the noise but the second I turned on my lights it started so I turned them off and it stopped a little. i turned them back on and it started making noise again. so I think it could be the one on the alternator but I dont know.
my car is a 1991 sentra SE-R and it has a bout 100,000 on it. so if you know anything please let me know. thank you
