When my car is in park, and turned off, I hear a clicking noise. So I went front of my car while its turned off, and kinda jerked the car back and forth, I hear a clicking clunking noise from my driver side tire only.
When the vehicle is in Park and handbrakes are not secure, rocking the vehicle would definitely result in crocking noises from the drive axles. Clicking noise after turning off engine are mostly from the exhaust system. They tend to click as they are cooling off. And is normal.
