In my case the noise is very very loud when turning right. Once the noise starts, you can hear it over speed bumps as well. The only strange thing is that is occurs more after the car has been running for a while.
It is important to note that although the noise is three going forward it is very loud while turning. Like the above post, yes the noise can be heard while the weight of the car is shifting; in my case under braking.
A week ago I took the latest built Focus, new car off the truck, for a ride and it behaves very differently; no noises what so ever. I took the car to see if I can reproduce the noises same as mine on the exact same curbs and nothing, very quiet. Also all new cars have the new sat nav os installed already.
