hey guys i was wondering if anyone can help me. When i drive down the road and press the gas i get a presistant humming noise, and when i let off it goes away. i just put on new cross drilled and slotted rotors and pads. it sounds like its comin from the back but why would it go away after i let off the gas if it was my brakes. Do yall think it could be my main belt? Or a sway bar? Please help. Its so annoying


Thanks

 

sounds like a rear end/axle bearing issue to me
