May you require any information to add, please let me know.

Answer
Yassin,

It sounds like you have replaced all of the normal parts that could cause this.  One thing that may be your problem would be a bent tire rim.  Even though they look good, you should have them checked for roundness.  

I would suggest that you have the front end aligned at a reputable shop, and see if they can find the problem, that you may have missed.  Some shops have a tire balancer that can spin the wheel while it is mounted on the car.  This way, any vibration, or balancing problems can be found.  It could, also be a worn steering box.
