Clicking sound coming from under the gas pedal

There is a clicking sound coming from under the gas pedal in my vehicle. Last week, I showed a master the front sets and he didn't see a problem, but he couldn't understand the sound either. There is no problem in gear shifts, there is no problem in car performance, but this sound started to come while the vehicle was walking in almost all gears. What do you think could be the problem? Could the steering box cause such a problem? or my luck. the sound comes from the front like a mechanical sound.
