I can hear it when my wife comes up the gravel driveway from about 600 feet away. I don' t hear it when she drives onto our long asphalt driveway though. Any spots on the prius that are prone to this before I start to dig in? Thanks.
Bounce up and down on each corner of the car with all your weight and try to make it make the noise...
probably the lower control arm mine have started clunking too a little bit on a dirt road I can hear it. A real low clunk clunk.
