I've notice when I tap the gas pedal slightly and release my foot off the gas pedal I hear a sound that goes CLUNK... near my passenger side front wheel. It also occurs if I have the car parked and push the car a bit back n let go it makes that sound. What could it be? I sometimes hear a whinning sound coming out from that side of the vehicle on the freeway.

I wasn't sure if it's the drive axle or something. Anyone experience this?
