After work intended to address a whine from the drivetrain, repeat the original conditions in a safe place and check whether the symptom returns. Record whether it follows road speed, acceleration, or deceleration and which direction the sound seems to come from. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Note tire changes and recent axle or differential work; sound can travel through the body. If the issue remains, return to the evidence instead of swapping another part.
Quick educational note
