Matt, If the noise occurs only on L/H OR R/H curves then it's probably a bad rear wheel bearing which is only generally noticeable at speeds over 45MPH. A front bearing problem would be most noticeable between 30 & 40MPH JFYI.

The car is an automatic with 8,400 miles and seems to make a subtle high pitched humming when I'm exceeding 45mph or so, only on acceleration. When I take the foot off the gas, no noise. Tran fluid always reads normal when engine is warm. Radio is off so there's no interference issues. Any suggestions or thoughts would be much appreciated.
