So tonight I was driving my car and when I got to about 110/120 MPH this really weird humming noise kicked on.....at first I thought it might have been the rev buzzer or whatever it is but it wasn't like a beep it was more of a hum...My car is an 07 STI and my boyfriend thinks it might be my differential... Should I take mu car in or should I have nothing to worry about???? HELP ME PLEASE!!!!!!!

 

I am in South America,Chile. My New Sti Limited 2007 with 200 kilometers, have a noise in front differential at 160-180 kms/hr, check in Dealer and say no special things, maybe....mass bearing....... I haved WRX 2006 no noise at 160-180......????

These cars use to "hum" around that speed due to the side mirrors. Maybe that's the same cause.

By the way, why were you going 110/120? Go 100. No humming.

 

I find once I pass 135mph ish the noise goes away

or you can put a small piece of electrical tape along the gap between the mirror and the mirror mount (where it pivots, on the bottom)

 

:armee_smilies122:

That's because you already went past the sound barrier.

 

Driving past the speed limit is bad mkay...

 

lol at the tape idea. Try folding your mirrors in then go 110+ (on closed course only) and see if it hums. If not then consider getting bling carbon fiber side mirrors. :couch2:

 

umm...slow down.

Problem solved. YWIA.
