02 avalanche whining only when accelerating

Asked by Ireland92 Nov 19, 2020 at 01:07 PM about the 2002 Chevrolet Avalanche 1500 4WD

Question type: Maintenance & Repair

When started it sounds like the alternator is dry on the inside, little bit of noise,
no whining or squealing. Only when accelerating to certain RPM'S it'll whine.
Once above set RPM(S) the whining stops. No problems with accelerating tho,
or shifting.
