How was the alternator replaced in 92 on a 95 model? If that's where the noise is coming from then that is likely the problem. I would replace the bearings & brushes if needed.I used a stethoscope on the alternator and heard a smooth sound on the front part but heard more noises coming from the back half. Is this something I should be alarmed over? Alternator was replaced with stock one in 1992. Should I replace with comp?
