2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic 9100 miles
when ever I am exellerating I hear a grinding noise. Its worst in hot weather. Its always starts grinding exactly when it hits 1500 rpm, and gets worse as rpms get higher. And I cant hear it below 1499 rpm. It doesnt get worse with speed, only when rpms are raised when moving. I put in in park and reved it up and didnt hear it at all. So I can be cruising at 60 and cant hear it unless the rpms are above 1500. Any ideas?
have the same problem?
