    SORRY I JUST COULD NOT RESIST, TAKE THE ALT. BELT OFF TO SEE IF NOISE STOPS
    IT SOUNDS LIKE ALT. HAS A DIFFERENT LOAD ON IT AND THAT COULD BE THE TROUBLE.
    OLD BATTERY COULD HAVE DAMAGED ALTERNATOR. CHECK CHARGING VOLTS AT BATT.
    SHOULD BE ABOUT 14V WITH ENG. AT IDLE.

    The whining does not start until you get up to 30 mph

    DON'T SEE ANY CONNECTION TO ALT. TRY THIS IF YOU CAN FIND A SAFE PLACE
    GET UP TO SPEED THAT NOISE STARTS, SHIFT TO NET. AND TURN OFF ENG. TO SEE IF NOISE STOPS.
    JUST BE CAREFUL BEST DONE ON STRAIGHT ROAD WITH NO SUDDEN STOPS. THAT WILL TELL IF NOISE
    IS IN ENG. COMPARTMENT OR DRIVE TRAIN. ALSO LOOK TO SEE IF ANYTHING ALTERED DUE TO BATT. SWAP
    AS RAM AIR AT 30 MPH MAY BE MAKING NIOSE FROM SOMETHING SHIFTED OUT OF PLACE. SOUNDS CRAZY BUT I HAVE
    HAD IT HAPPEN BEFOR!

    Yeah , I wonder where that came from!!!!!! .....Never mind , best laugh I had all day! But that's moot (that'll be ten cents please). WAY back to the noise thingy ..Does the noise start at 30 but when your slowing down it kinda hangs in there a little longer? Does it sound anything like being in a jet? I'm thinking poss. wheel bearing? BET Fred Flinstone didn't have these kind of problems with his car!

    I AGREE, THUS THE MORE REASON TO SHUT DOWN ENG. WHILE STILL MOVING.
    OUT HERE IN THE STICKS WE DO THAT TEST ALL THE TIME.

    I LIKE THAT MOOT THING!! I SAY IT ALL THE TIME NOW. WONDER WHAT THE POSTAL GUY FOUND OUT ON THE COROLLA?
