2010 Prius 140k + miles. Knocking sound coming from right wheel well while driving. Cannot hear it if windows are up. When window is down and a barrier is next to vehicle can hear knocking/clicking sound. I took it in to Toyota to diagnose and they said they could not hear anything and that they found to metal things in glove compartment and seperates them. Geez are they serious?! No foreign objects in tire. Replace front wheel hub assembly?
Welcome to the forum, Chris. Before you spend a lot of money, perhaps you would want to do a regular tire rotation. If the wheel still makes noise in its new location you have a defect in the tire.
I’d also advocate taking the tire off and performing your own inspection . This way you can see if there is a foreign object there, pads are thin, rotors are warped, etc. Good luck and keep us posted .
