I have an 04 automatic vibe. and anytime i go past 40 miles an hour and let it coast my two front wheels start singing to me it sounds like those glass cups when u rub ur finger on the rim.Any ideas what it could be ?

yea im usually backing out my house or school parking lot thats when it happens everyone can hear it , could it be the exhasut and im taking it in as soon as my alero is back from the shop ill post when i know

o yea im sorry its automatic, and yea it shuold be only a few thuosand miles on it, once i put it into drive its fine and drives well, just reverse is it worth bringing into the shop?

i got a 2005 vibe and anytime i throw it into reverse it sounds as if a rocket is taking off and the car is shaking violently loud any ideas on what could cause this? i got to walk 10 miles to school if this is serious =/
