Loud Vibrating Sound under the chassis - could be the suspension...
i think i may have a problem with the rear suspension under the chassis (or still dont know if it is the problem)... everytime i drive
upto 80-90k/ph i can hear a loud grinding and vibrating "woom" noise under the car...other than the backfire and muffler sound,
this woom is much louder when i run the highway...it's coming from the back of the car...i dont know if it's the bearing that holds
the wheels to the axle or any part of the wishbone or the sway bars...i need help, i gotta find out what it is so i can take care of
wheel bearing maybe? i dont really know what sound "woom" makes online
the "woom" is like the sound of the loose bearing grinding with the drum inside the wheel...kinda like the sound of a Ducati when idle but a bit louder and scarier...
