if its a front wheel drive vehicle then it could be the axels
Worn Ball Joint
I would have your exaust pipe looked at, it might be loose, or might even be missing a bracket.
Could be a worn out shock or wheel bearings. Is it 4 wheel drive?
Vibration is necessary because it creates a disturbance in the medium (such as air) which then propagates as a wave. This disturbance causes molecules in the medium to oscillate back and forth, transferring energy and producing a sound wave. Without the initial vibration, there would be no energy to propagate the wave and create sound.
Is it accompanied by a shuddering or vibration? You could likely have bad brake rotors.
It may be your catalytic converter. Ours did the same thing with an automatic transmission. We sometimes thought it was the transmission, then we received a recall on the converter. Took it in to be replaced, and no more rattling.
The rapid back and forth of air or other matter is the sounds vibration (vibration is the anwser).
Check your muffler pipes.
Check pLugs and wires and the vibration my be from brake pads or warped rotors
It would be different pich
bad transfer case
