We have replace upper bushing and i ve made a alignment check with a specialist.
We have checked pad, caliper permute wheel pad...
Now in acceleration, pulling is disappeared...but there still a very little bit pulling at constant speed. And a very important pulling to the left on braking....
But i ve discovered something when i remove wheel an pad, the left hub is a little bit more hard to turn.
When i drive a long time, when everything is hot the pulling increase.
The pulling is very present on brake....more the car/wheel is hot, more the pulling increase..
After a long travel, the center of the wheel is very hot (both side). and it become noisy a "tchip tchip" like a bird

My conclusion is that my front wheel bearing are out of order....
Is someone has had this kind of problem?
The essential question is "is it possible that a very important pulling to one direction when braking is due to a bad front wheel bearing?"
Thanks for your help
