Question about 2006 Chevrolet Trailblazer
Altenator bearings are whinning - how do I change altenator?
Don' t be so quick to think that it is the bearings. If the noise gets louder with acceleration try the alternator tensioner first. Mine was doing the same thing. Whining noise at start up and louder upon acceleration. Replaced alternator tensioner and the noise is gone. Hope this helps
