Hi

You have swap a lot there to fix that problem! You did mention it vibrate on idle also. How much is your car driven? Have you change lambdas? My car did vibrate on idle but not just the steering wheel and it stopped when all lambdas were swap to new ones. Also many more things get better, like throttle response etc.

I didn't change that as it didn't come to my mind that the problem vibration in steering wheel would come from it ..

forget to mention also that the wheel bearing has been checked but its all good

do you think it may be the steering box have any screw lose or something which make it vibrate ?

what makes me crazy that it keep going and coming
today i drive the car and get know its fully no vibration when i was idle and rpm was at 500

STOP guessing, and take it to either the dealership or an independent for a proper diagnosis.
