03 silverado 5.3 intermittent noise at 40mph!
Hi there! I am experiencing this audible whining noise when cruising at 40mph. Its especially noticeable on decel, but also comes in and out as the tranny downshifts. Also when goin over bumps at 40 you hear the whine intermit. If I try to take a passenger for a ride to show them what Im talkin about, it wont whine at all. Im thinkin maybe the carrier bearing or tranny but not sure. went from having a slight vibration to this whine noise after having the tires rotated and balanced also. Could use some help on this one, Thanks!!2003 Silverado LS 1500 Xcab 5.3 vortec 3.73 rear.
