I've been hearing a howling noise inside the vehicle which seems to only happen between 45-70 kph. My mechanic has check the wheel bearings which is not the problem.
I've done some research any have found a TSB related to this issue.
• TSB #00063 -- SOME MINIVANS MAY EXHIBIT A HOWL SOUND WHEN DRIVING AT SPEEDS BETWEEN 45 AND 70 MPH AND THAT MAY BE MOST NOTICEABLE AT 58 - 60 MPH. *TT (NHTSA ID #615696, NOVEMBER 10 2000)
Does anyone have details for this TSB?
