loud bang under the car

It could be your front disc brake pads moving into position, this = usually happen right after you start moving forward but in your case = this may happen on the right side after ten minutes.

hello again...I am clarifying the problem I seem to be having with my Toyota Camry...after ten minutes of driving, every single time, I hear a loud bang coming from underneath the car - sounds like the right side...it sounds like a rock hitting the car...it only happens once every time I drive...any ideas?...much appreciate it...thanks

Try moving your car forward then brake, select reverse and move then brake. If you can reproduce the noise this way it maybe a suspension/braking component which an observer (outside the car) maybe able to get a line on.

As mentioned before, the exhaust system maybe hitting the floor when the motor moves in its mounts,...worth checking out.

Also a loose baffle in the muffler can make a VERY loud noise if its forced to move under exhaust-gas pressure once the muffler is up to full operating temp.
